To prevent the `.product_code` event from being triggered when the "Clear" button (`.clear_pro_btn`) is clicked, you can use a flag or temporarily disable the event while clearing the fields.

### **Solution: Using a Flag**
Modify the `.clear_pro_btn` click function to set a flag before clearing and use that flag in the `.product_code` event.

var preventProductCodeTrigger = false;

jQuery('.clear_pro_btn').click(function() {
    preventProductCodeTrigger = true; // Set flag to prevent event

    var pId = jQuery(this).attr('data-pid');
    parentRow = jQuery(this).closest('.product-id-'+pId);
    parentRow.find('.product_code').val('');
    parentRow.find('.p_depth').val('');
    parentRow.find('.p_width').val('');
    parentRow.find('.variation-select').val('');
    parentRow.find('.p_bmt').val('');
    parentRow.find('.p_length').val('');
    parentRow.find('.p_weight').val('');
    parentRow.find('.pa_use-type').val('');
    parentRow.find('.pf_add_to_project').attr('data-vpid', '').hide();
    parentRow.find('.pf_pdf_preview').attr('href', 'javascript:void(0);').hide();
    parentRow.find('.clear_pro_btn').attr('data-pid', '');

    setTimeout(function() {
        preventProductCodeTrigger = false; // Re-enable event after clearing
    }, 100); // Small delay to allow the clearing process to finish
});

jQuery('.product_code').on('blur input', function(e) {
    if (preventProductCodeTrigger) {
        return; // Stop execution if flag is set
    }

    e.preventDefault();
    
    var thisVal = jQuery(this);
    var sku = thisVal.val();
    
    if (!sku) {
        return; // If SKU is empty, do nothing
    }

    var parentProductId = thisVal.attr('data-pid');
    console.log(parentProductId);
    console.log("dfd"+sku);
    
    jQuery.ajax({
        type: 'POST',
        url: '<?php echo admin_url('admin-ajax.php'); ?>',
        data: {
            action: 'get_variation_id',
            sku: sku,
            parent_product_id: parentProductId,
        },
        success: function(response) {
            if (response.success) {
                parentRow = thisVal.closest('.product-id-'+parentProductId);
                parentRow.find('.pa_depth').val(response.data.p_depth);
                parentRow.find('.p_width').val(response.data.p_width);
                parentRow.find('.pa_width').val(response.data._width_field);
                parentRow.find('.p_length').val(response.data.p_length);
                parentRow.find('.pa_mils').val(response.data.p_bmt);
                parentRow.find('.pa_coating').val(response.data.pa_coating);
                parentRow.find('.p_weight').val(response.data.p_weight);
                parentRow.find('.pa_use-type').val(response.data.p_type);
                parentRow.find('.pa_leg-height-in').val(response.data.legheight_field);
                parentRow.find('.pf_add_to_project').attr('data-vpid', response.data.variation_id).show();
                parentRow.find('.pf_pdf_preview').attr('href', response.data.dtp_field).show();
                parentRow.find('.clear_pro_btn').attr('data-pid', parentProductId);
                console.log(response);
            }
        }
    });
});

### **How This Works**
1. **Flag `preventProductCodeTrigger` is set to `true`** before clearing the input fields.
2. **The `.product_code` event checks this flag** before proceeding. If the flag is `true`, the event stops execution.
3. **A `setTimeout` resets the flag to `false` after 100ms** to allow normal behavior afterward.
4. **Added a condition to prevent AJAX call if the SKU is empty** to avoid unnecessary requests.

This ensures that the AJAX request does not fire when the fields are being cleared via the "Clear" button.

.product_code input is empty when clear but still getting old value of we are using
Assistant
It looks like when clearing `.product_code`, the old value is still being retrieved due to the behavior of the “, browser auto-fill, or caching. The browser may be keeping the previous value in memory, causing it to reappear even after you clear it.

### **Solution**
1. **Explicitly set `val('')` and trigger a change event**
2. **Use `.prop('value', '')` as a backup**
3. **Remove focus from the input after clearing**
4. **Set a timeout to ensure the change is reflected**

#### **Updated jQuery Code**

var preventProductCodeTrigger = false;

jQuery('.clear_pro_btn').click(function() {
    preventProductCodeTrigger = true; // Set flag to prevent event

    productCodeInput.val(''); // Clear input value
    productCodeInput.prop('value', ''); // Force reset
    productCodeInput.trigger('input'); // Trigger input event to notify changes
    productCodeInput.trigger('change'); // Ensure UI updates
    productCodeInput.blur(); // Remove focus to avoid browser autofill

    // Clear other fields
    parentRow.find('.p_depth').val('');

    }, 100); // Small delay to ensure UI updates
});

jQuery('.product_code').on('blur input', function(e) {

    var parentProductId = thisVal.attr('data-pid');
    console.log(parentProductId);
    console.log("dfd" + sku);
    
    jQuery.ajax({

                parentRow.find('.pa_depth').val(response.data.p_depth);
                parentRow.find('.p_width').val(response.data.p_width);
                parentRow.find('.pa_width').val(response.data._width_field);

### **Key Fixes & Enhancements**
✅ **`val('')` and `prop('value', '')`** – Ensures value is removed from both UI and JavaScript memory.
✅ **`trigger('input')` and `trigger('change')`** – Notifies the browser that the value has changed, preventing ghost values from “.
✅ **`blur()`** – Forces the field to lose focus, preventing the browser from retaining the old value in suggestions.
✅ **Ensures AJAX is not triggered on empty values** after clearing.
✅ **Flag `preventProductCodeTrigger`** prevents unnecessary AJAX calls when clearing.

This should now properly clear the `.product_code` field and prevent the old value from reappearing. 🚀

If clearing the `.product_code` field still retains the old value despite setting it to an empty string, it is likely due to:
1. **Browser autocomplete/autofill interference**
2. **Datalist holding onto the value in memory**
3. **Event bubbling causing the previous value to persist**

### **Updated Solution**
Try these changes to **forcefully reset the field properly**:

#### **1️⃣ Explicitly Reset Input Value and DataList**

var preventProductCodeTrigger = false;

jQuery('.clear_pro_btn').click(function() {
    preventProductCodeTrigger = true; // Set flag to prevent triggering AJAX on input clear

    var pId = jQuery(this).attr('data-pid');
    var parentRow = jQuery(this).closest('.product-id-' + pId);

    var productCodeInput = parentRow.find('.product_code');

    // Clear the input field properly
    productCodeInput.val(''); // Reset the field
    productCodeInput.prop('value', ''); // Ensure it's empty in JavaScript memory
    productCodeInput.trigger('input').trigger('change'); // Trigger update event
    productCodeInput.blur(); // Remove focus to avoid autofill

    // Workaround for datalist retention
    setTimeout(() => {
        productCodeInput.val('').trigger('input').trigger('change'); // Ensure full reset
    }, 50);

    // Clear other fields
    parentRow.find('.p_depth, .p_width, .variation-select, .p_bmt, .p_length, .p_weight, .pa_use-type').val('');
    parentRow.find('.pf_add_to_project').attr('data-vpid', '').hide();
    parentRow.find('.pf_pdf_preview').attr('href', 'javascript:void(0);').hide();
    parentRow.find('.clear_pro_btn').attr('data-pid', '');

    setTimeout(() => {
        preventProductCodeTrigger = false; // Allow events again
    }, 100);
});

jQuery('.product_code').on('blur input', function(e) {
    if (preventProductCodeTrigger) {
        return; // Stop execution if the flag is set
    }

    e.preventDefault();

    var thisVal = jQuery(this);
    var sku = thisVal.val().trim(); // Trim to remove accidental spaces

    if (!sku) {
        return; // Do not proceed if SKU is empty
    }

    var parentProductId = thisVal.attr('data-pid');
    console.log("Processing SKU: ", sku, " for Product ID: ", parentProductId);

    jQuery.ajax({
        type: 'POST',
        url: '<?php echo admin_url('admin-ajax.php'); ?>',
        data: {

### **Key Fixes & Enhancements**
✅ **Double Reset Approach**
– Clears the field immediately
– Uses `setTimeout()` to ensure no residual value is stored by the browser

✅ **`blur()` to remove focus**
– Prevents browser autocomplete from interfering

✅ **Prevent Event Triggering During Clearing**
– Uses a `preventProductCodeTrigger` flag to stop AJAX from running on clear

✅ **Trim Spaces Before Checking SKU**
– Handles cases where a hidden space might be causing the input to appear filled

—

### **Try These Additional Fixes If Still Not Working**
1. **Disable browser autocomplete** by adding `autocomplete="off"` to “:

<input autocomplete="off" list="product_code-<?php echo $product->get_id(); ?>" class="product_code" name="product_code">

2. **Check If Another Script Is Resetting the Value**
– Open the browser console (`F12`) and run:

jQuery('.product_code').val('');

– If the value does not clear, another script is interfering.

3. **Check If JavaScript Error Is Preventing Execution**
– Open the console (`F12` > Console Tab) and look for errors.

Let me know if it's still not clearing properly! 🚀

If you want a solution **without using `preventProductCodeTrigger`**, you need to ensure that when the **Clear button** is clicked, the input field is properly reset, and the event handler (`blur` or `input`) does not get triggered with old values.

### **Changes & Fixes Without `preventProductCodeTrigger`**
✅ **Double Reset Approach**:
– Clears `.val('')` immediately
– Uses `setTimeout()` to ensure the browser does not retain the value
– `prop('value', '')` makes sure JavaScript memory is cleared

✅ **Prevents AJAX Call on Empty Input**:
– If the `.product_code` input is empty, it **stops the AJAX request**

✅ **`blur()` to Prevent Autofill**:
– Ensures old values do not get filled again by the browser

✅ **Does Not Use Any Flag (`preventProductCodeTrigger`)**

—

### **Try These Additional Fixes If Needed**
1. **Disable Browser AutoComplete in Input Field**

<input autocomplete="off" list="product_code-<?php echo $product->get_id(); ?>" class="product_code" name="product_code">

2. **Manually Clear Datalist**
If the “ is causing the issue, try clearing it as well:

parentRow.find('datalist option').remove();

This solution should now properly clear the `.product_code` input and prevent old values from reappearing! 🚀

If the old value is still appearing after clearing the input, the issue is likely due to browser autocomplete, `datalist` behavior, or jQuery event propagation. Since you want a **solution without `preventProductCodeTrigger`**, let's take a different approach.

### **Why This Works**
✅ **Clears input in multiple ways** (`val('')`, `prop('value', '')`, `attr('value', '')`)
✅ **Recreates “ to prevent ghost values from browser cache**
✅ **Ensures `blur()` removes focus properly**
✅ **Prevents AJAX from triggering if the field is empty**
✅ **No need for `preventProductCodeTrigger` flag**

—

### **If The Issue Still Persists**
Try disabling browser autocomplete:

<input autocomplete="off" list="product_code-<?php echo $product->get_id(); ?>" class="product_code" name="product_code">

This should fully reset the input field without retaining old values. 🚀 Let me know if it works for you!

clear value in datalist
Assistant
If the “ is still holding onto old values, you need to **clear the existing options inside the “** when the "Clear" button is clicked. This will ensure that no old values are retained.

## **Updated jQuery Code (Including Clearing `datalist`)**

jQuery('.clear_pro_btn').click(function() {
    var pId = jQuery(this).attr('data-pid');
    var parentRow = jQuery(this).closest('.product-id-' + pId);
    var productCodeInput = parentRow.find('.product_code');

    // Get datalist ID and clear its options
    var dataListId = productCodeInput.attr('list');
    var dataList = jQuery('#' + dataListId);
    dataList.empty(); // Remove all existing options from datalist

    // Completely clear the input field
    productCodeInput.val(''); 
    productCodeInput.prop('value', ''); 
    productCodeInput.attr('value', ''); 
    productCodeInput.trigger('input').trigger('change'); 
    productCodeInput.blur(); // Remove focus to prevent browser autocomplete

    // Clear other related fields
    parentRow.find('.p_depth, .p_width, .variation-select, .p_bmt, .p_length, .p_weight, .pa_use-type').val('');
    parentRow.find('.pf_add_to_project').attr('data-vpid', '').hide();
    parentRow.find('.pf_pdf_preview').attr('href', 'javascript:void(0);').hide();
    parentRow.find('.clear_pro_btn').attr('data-pid', '');

    console.log("Cleared product fields and datalist for Product ID: " + pId);
});

// Event listener for input field changes
jQuery('.product_code').on('blur input', function(e) {
    var thisVal = jQuery(this);
    var sku = thisVal.val().trim(); // Trim to remove accidental spaces

    if (!sku) {
        console.log("No SKU entered, skipping AJAX call.");
        return;
    }

    var parentProductId = thisVal.attr('data-pid');
    console.log("Fetching details for SKU:", sku, "Product ID:", parentProductId);

    jQuery.ajax({
        type: 'POST',
        url: '<?php echo admin_url('admin-ajax.php'); ?>',
        data: {
            action: 'get_variation_id',
            sku: sku,
            parent_product_id: parentProductId,
        },
        success: function(response) {
            if (response.success) {
                var parentRow = thisVal.closest('.product-id-' + parentProductId);
                parentRow.find('.pa_depth').val(response.data.p_depth);
                parentRow.find('.p_width').val(response.data.p_width);
                parentRow.find('.pa_width').val(response.data._width_field);
                parentRow.find('.p_length').val(response.data.p_length);
                parentRow.find('.pa_mils').val(response.data.p_bmt);
                parentRow.find('.pa_coating').val(response.data.pa_coating);
                parentRow.find('.p_weight').val(response.data.p_weight);
                parentRow.find('.pa_use-type').val(response.data.p_type);
                parentRow.find('.pa_leg-height-in').val(response.data.legheight_field);
                parentRow.find('.pf_add_to_project').attr('data-vpid', response.data.variation_id).show();

                console.log(response);
            }
        }
    });
});

### **What This Fix Does**
✅ **Clears all “ values from “ using `.empty()`**
✅ **Ensures input field is completely reset (`val('')`, `prop('value', '')`, `attr('value', '')`)**
✅ **Triggers `blur()` to prevent browser autocomplete from showing old values**
✅ **Prevents AJAX call if the field is empty**

—

### **If The Issue Still Persists**
Try setting the “ to a **new empty instance** after clearing:

jQuery('#' + dataListId).replaceWith('<datalist id="' + dataListId + '"></datalist>');

This **removes the old datalist and replaces it** with an empty one.

Now, when you click the **Clear button**, the input and datalist should both be completely reset. 🚀 Let me know if this works for you!

User
trigger clear_pro_btn on other event
Assistant
To trigger the `.clear_pro_btn` click event from another event (e.g., when the user selects a new product code or performs another action), you can manually trigger it using `.trigger('click')` or `.click()`.

—

### **Example: Trigger `clear_pro_btn` on Another Event**
#### **1️⃣ Trigger when selecting a new product code from “**

jQuery('.product_code').on('change', function() {
    var parentRow = jQuery(this).closest('.product-input');
    parentRow.find('.clear_pro_btn').trigger('click'); // Simulate clicking the clear button
});

**Behavior**:
Whenever the user selects a new product code, it **automatically clears** the previous data by triggering the `.clear_pro_btn` event.

—

#### **2️⃣ Trigger when clicking another button (`.some_other_btn`)**

jQuery('.some_other_btn').on('click', function() {
    jQuery('.clear_pro_btn').trigger('click');
});

**Behavior**:
When `.some_other_btn` is clicked, it will **simulate clicking the `.clear_pro_btn`** and reset everything.

—

#### **3️⃣ Trigger when the user starts typing in `.product_code`**

jQuery('.product_code').on('input', function() {
    jQuery(this).closest('.product-id-' + jQuery(this).attr('data-pid')).find('.clear_pro_btn').trigger('click');
});

**Behavior**:
Whenever the user starts typing in `.product_code`, it **automatically clears the fields** before fetching new values.

—

### **Final Thoughts**
By triggering `.clear_pro_btn.click()` from another event, you can reset the values when:
✅ A new product is selected (`change` event)
✅ Another button is clicked (`click` event)
✅ The user starts typing a new product code (`input` event)

Let me know which event you need to trigger from, and I can refine the solution further! 🚀

User
optioan parameter in jas function
function getSavedProduct(id, firstOrLast)
Assistant
In JavaScript, you can set an **optional parameter** in a function by providing a **default value**. If the caller does not pass a value for the parameter, the default value will be used.

—

## **Solution: Using Default Parameter**

function getSavedProduct(id, firstOrLast = 'first') {
    console.log("Product ID:", id);
    console.log("Position:", firstOrLast);
}

// Example Calls
getSavedProduct(123);        // Output: Product ID: 123, Position: first
getSavedProduct(456, 'last'); // Output: Product ID: 456, Position: last

**✅ Default value (`firstOrLast = 'first'`) ensures it works even if the second parameter is missing.**

—

## **Alternative: Using `if` Check for Undefined**
Another way to handle optional parameters is by checking if the value is `undefined` inside the function:

function getSavedProduct(id, firstOrLast) {
    if (typeof firstOrLast === 'undefined') {
        firstOrLast = 'first'; // Set default manually
    }
    console.log("Product ID:", id);
    console.log("Position:", firstOrLast);
}

// Example Calls
getSavedProduct(789);        // Output: Product ID: 789, Position: first
getSavedProduct(999, 'last'); // Output: Product ID: 999, Position: last

**✅ This is useful if you need more complex conditions for setting the default.**

—

## **More Robust Approach: Using ES6 Destructuring**
If you expect more parameters in the future, use an **object with destructuring**:

function getSavedProduct({ id, firstOrLast = 'first' }) {
    console.log("Product ID:", id);
    console.log("Position:", firstOrLast);
}

// Example Calls
getSavedProduct({ id: 123 });               // Output: Product ID: 123, Position: first
getSavedProduct({ id: 456, firstOrLast: 'last' }); // Output: Product ID: 456, Position: last

**✅ Scales better when adding more parameters.**

—

### **Best Practice**
– ✅ Use **default parameters** (`firstOrLast = 'first'`) for simple cases.
– ✅ Use **manual `if` checks** when default values need to be dynamically assigned.
– ✅ Use **destructuring** when handling multiple optional parameters for better readability.

User
convert comma seperated value in array in js and then
jQuery(`.cpbtn`+productid).trigger('click');
compare product id and click trigger
Assistant
To convert a **comma-separated string** into an **array** in JavaScript and then trigger the `.cpbtn` click event for matching product IDs using jQuery, follow these steps:

—

## **Solution**

// Example comma-separated values (CSV) of product IDs
var productIds = "101,202,303,404";

// Convert CSV string to an array
var productIdArray = productIds.split(',').map(id => id.trim()); // Ensure IDs are trimmed

// Iterate through the array and trigger click for each matching product ID
productIdArray.forEach(productId => {
    jQuery(`.cpbtn${productId}`).trigger('click');
});

—

### **How This Works**
1. **`split(',')`** → Converts the string `"101,202,303,404"` into an array: `["101", "202", "303", "404"]`.
2. **`map(id => id.trim())`** → Ensures each ID is **trimmed** to remove extra spaces.
3. **`forEach(productId => { jQuery(`.cpbtn${productId}`).trigger('click'); })`**
– Iterates through the array.
– Triggers a click event on elements with class `.cpbtn101`, `.cpbtn202`, etc.

—

### **Example Use Case**
If your HTML has buttons like this:

<button class="cpbtn101">Click 101</button>
<button class="cpbtn202">Click 202</button>
<button class="cpbtn303">Click 303</button>
<button class="cpbtn404">Click 404</button>

The script will **automatically trigger clicks** on the matching buttons.

—

### **Final Output**
If `productIds = "101,202,303,404"`, it will:
✅ Click `.cpbtn101`
✅ Click `.cpbtn202`
✅ Click `.cpbtn303`
✅ Click `.cpbtn404`
