Sometimes in our development process, we need to convert the JS object and the jquery object:

1.js objects are directly enclosed in $ () when they go to a jquery object.

Like what:

var v = document.getElementById( "v" ); //DOM对象 var $v = $(v); //jQuery 对象2.jquery Turn JS object:

2. JQuery objects into DOM objects

Two ways to convert a JQuery object into a DOM object: [index] and. get (index);

(1) JQuery object is a data object, you can get the corresponding DOM object by means of [index].

Such as:

var $v = $( "#v" ); //jQuery 对象 var v = $v[0]; //DOM 对象

(2) JQuery itself provides, through the. Get (index) method to get the corresponding DOM object

Such as:

var $v = $( "#v" );  //jQuery 对象 var v = $v.get(0);  //DOM对象 ( $v.get()[0] 也可以 )
