I came across the window.prompt() method, which has never been used before. But let's do it now.

In the web page, sometimes need to pop up a prompt box, and in the prompt box also need the user to enter 1 some content, this can use prompt object, the specific implementation of the usage is as follows.


<!DOCTYPE html>
 <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <script>
   var _saytext = decodeURI(" How stupid of me ");
   
   var _text;
   
   var err_list = new Array(" Don't fill it out!! "," Fill it out, don't try!! ");
   
   _text = prompt(" Enter" " + _saytext +" " ");
   
   for ( i = 0; _text != _saytext; ++i) {
     if ( i == err_list.length) {
      i = 0;
     }
     alert(err_list[i]);
     _text = prompt(" Enter" " + _saytext +" " ");
   }
   
   alert(" Well, that's right! ");
 </script>
 </head>
 </html>

That's all for this article, I hope you enjoy it.
