2. Error cause

Because the element is added to the div, append () is used ();

$ ("# DivStyle"). append ("<div> <label> _ data [I]. name </label> </div> ");

The append contains dynamic data. When the request data is empty, obtain and determine the content in the div:

Var divContent = $ ("# divStyle" ).html (); if (divContent = null | divContent. length = 0) {$ ("# divStyle "). append ("<div>  </div> ");}

When the judgment is made, it never enters the if, and then uses the console for debugging. Even if there is no data div, there are many spaces and line breaks in it.
