How to focus the text box in JQuery Example Analysis _ jquery-js tutorial

This article mainly introduces JQuery's method of getting the focus of the text box, and analyzes jQuery's skill in getting the focus of the text box, if you need it, you can refer to the example in this article to analyze the method of getting the focus of the text box in JQuery. Share it with you for your reference. The specific analysis is as follows:

Because the object obtained in JQuery is still a JQuery object, using focus () only enables this object to obtain the onFocus () function. It cannot be the object that gets the focus, so it is necessary to get the focus of the object, the focus Method of the DOM object should be called, namely:

$ ("# Id") [0]. focus ();

Note the differences between the two functions:

$ ("# Id"). focus ();

$ ("# Id") [0]. focus ();

The first is to increase the onFocus () time, and the other is to make the DOM object focus.

I hope this article will help you with jQuery programming.
