What does this mean in jquery
this is the dom object. To put it bluntly, it is the tags in html. $(this) is the dom object. The object is changed to a JQuery object, so that the Dom object can be processed using JQuery methods later.
First, let’s take a look at the $() symbol in JQuery. In fact, this symbol is equivalent to JQuery() in JQuery, that is, $(this)=jquery(); that is, this can return a jquery object. Then, when you alert($('#id')); on the web page, an [object Object] will pop up. This object object is also a jquery object.
The example is as follows:
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<script src="https://cdn.staticfile.org/jquery/3.6.0/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("p").click(function(){
$(this).hide();//$(this)是在方法click内，此处的$(this)表示的是当前调用click方法的对象$("p")，就是表示当前对象，当前调用该方法的对象
});
});
</script>
</head>
<body>
<p>如果您点击我，我会消失。</p>
