The event method of mouse movement in jquery is ()

jQuery is one of the most widely used JavaScript libraries currently. It encapsulates many JavaScript operations, which greatly facilitates the work of front-end developers. In jQuery, mouse movement events are very common, and developers can use different methods to handle these events.

Next, let’s take a look at the event methods of mouse movement in jQuery.

First of all, you need to know that there are two ways to handle mouse movement events in jQuery: mousemove() and hover().

The mousemove() method is used to bind mouse movement events. This event is triggered when the mouse moves over the specified element. This event has a callback function in which operations after mouse movement can be processed.

The following is an example of using the mousemove() method:

$(document).mousemove(function(e){
  console.log('鼠标移动到了（' + e.pageX + '，' + e.pageY + '）的位置。');
});

This code will bind a mousemove() event to the entire document. When the mouse moves, the callback function will be called. , and output the current position of the mouse.

Another commonly used method is hover(), which is used to bind the entry and exit events of mouse movement. When the mouse enters or leaves the specified element, the corresponding events will be triggered respectively. The hover() method has two callback functions, one is the callback function when the mouse enters, and the other is the callback function when the mouse leaves.

The following is an example of using the hover() method:

$('div').hover(function(){
  $(this).css('background-color', 'red');
}, function(){
  $(this).css('background-color', 'green');
});

This code will bind the entry and exit events of the div element. When the mouse enters the div element, the element will turn red. , the element will turn green when the mouse is moved away.

In general, mouse movement events are very common in jQuery, and mousemove() and hover() are two common methods for handling these events, and they are suitable for different scenarios. Developers can choose and use the corresponding method to handle mouse movement events based on actual needs.
