Call the focus of the DOM object to get the focus of the text box _ jquery

To get the focus of an object, you should call the focus Method of the DOM object. The following is a good example. You can refer to the object obtained in JQuery or the JQuery object, the use of focus () only enables the object to get the onFocus () function, but cannot be the object to get the focus. To get the focus of the object, you should call the focus Method of the DOM object, that is:

The Code is as follows:

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

Note the differences between the two functions:

The Code is as follows:

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

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