jQuery mouseover() method

The mouseover() method in jQuery is an event handler that allows you to attach a function to be executed when the mouse pointer enters the area of a selected element or its child elements. It is triggered when the mouse pointer moves over the specified element or hovers over it.

The syntax for using the mouseover() method is as follows:

$(selector).mouseover(function(event) {
  // Function body
});

• selector: It is a string that specifies the elements to be selected.
• function(event): The callback function that will be executed when the mouseover event occurs. It takes one argument:
• event: The event object containing information about the mouseover event. It provides details about the event, such as the mouse position, the target element, and other related information.

Here’s an example of how you can use the mouseover() method:

HTML:

<div id="myDiv" style="width: 100px; height: 100px; background-color: blue;"></div>

JavaScript:

// Attach a mouseover event handler to the div element
$('#myDiv').mouseover(function(event) {
  $(this).css('background-color', 'red');
});

In the above example, when you move the mouse pointer over the div with the ID “myDiv,” the mouseover() event handler will be triggered, and it will change the background color of the div to red.

The mouseover() event is commonly used to create interactive hover effects or trigger actions when the mouse pointer enters an element. It can be combined with other events like mouseout or click to create more complex interactions or to implement custom mouse interactions for various UI elements.

Remember that the mouseover() event is similar to the mouseenter() event, but with one key difference: mouseover triggers when the mouse pointer enters the element or any of its child elements, while mouseenter triggers only when the mouse pointer enters the element itself and not its child elements.
