In jQuery, the `.click()` event is used to execute a function when an element is clicked. You can bind a click event in multiple ways:
### 1. **Basic Click Event**
$(document).ready(function(){
$("#myButton").click(function(){
alert("Button clicked!");
});
});
π **Explanation:** When `#myButton` is clicked, an alert box will appear.
—
### 2. **Using `.on()` (Recommended for Dynamic Elements)**
$(document).ready(function(){
$(document).on("click", "#myButton", function(){
alert("Button clicked dynamically!");
});
});
π **Why use `.on()`?**
If `#myButton` is dynamically added after the page loads, `.click()` wonβt work, but `.on()` will.
—
### 3. **Passing Data in Click Event**
$("#myButton").on("click", { msg: "Hello, Neeraj!" }, function(event){
alert(event.data.msg);
});
π **Explanation:** Data `{ msg: "Hello, Neeraj!" }` is passed and retrieved inside the event handler.
—
### 4. **Prevent Default Behavior**
$("a").click(function(event){
event.preventDefault();
alert("Link clicked, but default action prevented!");
});
π **Use case:** Prevents the link from navigating to another page.
—
### 5. **Toggle Class on Click**
$("#myButton").click(function(){
$(this).toggleClass("active");
});
π **Use case:** Toggles a class `active` on the button when clicked.
