jquery Chinese text box get focus

Today, a small problem is that the text box needs to be entered in order to submit, if you do not enter the prompt and make the text box to get focus!

Such a simple thing is not an object if you don't use jquery. focus () It's all right,

But when we used jquery so $ ("#nameInput") returned was not a DOM object but a jquery object,

In this case $ ("#nameInput"). focus () The meaning of this method has changed,

Instead of getting the text box to focus, trigger the text box to bind all the functions in the onfocus!

In fact, it's very easy to use jquery to convert a jquery object into a DOM object, which I believe developers have long thought about, but it's first.

$ ("#nameInput") [0].focus () simple plus one [0] is what we want!!
