jQuery gets DOM node instance analysis (2 ways)_jquery

The example in this article describes how to obtain DOM nodes with jQuery. Share it with everyone for your reference, the details are as follows:

The wrapped DOM object in jQuery is actually an array. There are two ways to obtain a pure DOM object:

1. Use array index to access , for example:

Copy code The code is as follows:

var dom = $(dom)[0];

2. Use the function get() to access , for example:

Copy code The code is as follows:

var dom = $(dom).get(0);

The parameter in the get() function is the index number.

3. Example

var div = document.createElement("DIV");
div.innerText = "TEST IS OK!";
document.body.appendChild(div);
var $tmp = $(div);
alert($tmp[0].innerText); //方式1获取DOM节点对象
alert($tmp.get(0).innerText); //方式2获取DOM节点对象

I hope this article will be helpful to everyone in jQuery programming.
