This example analyzes the method of making a text box focus in JQuery. Share it with everyone for your reference. The specific analysis is as follows:

Since the object obtained in JQuery is still a JQuery object, using focus() on it only causes the object to obtain the onFocus() function , the object cannot get focus, so to make the object get focus, you should call the focus method of DOM object , that is:

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

You need to pay attention to the difference 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 gain focus.
