Talk about createElement events in javascript

CreateElement is the concept of creating child nodes, or child elements, in HTML using the W3C DOM image model

 <script>

   window.onload = function () {

   var input  = document.createElement('input');

   var button = document.createElement('input');

   input.type ='text';  

   input.id= 'text';

   input.value ='1';

   button.type='button';

   button.value =' One by one to add ';

   button.style.width = '40px';

   button.style.height = '23px';

   document.body.appendChild(input);

   document.body.appendChild(button);

   button.onclick = function(){

      var value = input.value;

      input.value = value * 1 + 1;

   }

  }

 </script>

  Note: value is actually a character, if input. Value =value*1+1; For input. Value = value + 1; The result will be 111111, which is incremented by 1, so the value*1 will be able to convert the value to Int.

Conclusion:

To finally resolve the compatibility issue with the createElement method, it is important to note that the browser still USES the W3C specification's standard approach for non-internet explorer to use its unique method of passing in a legitimate HTML code string as a parameter for createElement.
