CodePudding user response:

 & lt; A id="login - BTN" & gt; Button & lt;/a> 
 The default hidden div
 
<script> 
(function () {
Var BTN=document. GetElementById (' login - BTN); 
Var box=document. GetElementById (' login box - '); 
var timer=null; 
Box. onm ouseover=BTN. onm ouseover=function () {
If (timer) clearTimeout (timer) 
='block' box. Style. The display; 
} 
Box. The onm ouseout=BTN. onm ouseout=function () {
The timer=setTimeout (function () {
='none' box. Style. The display;
