[Javascript] how can change select's options dynamic

Mon Oct 14 00:54:52 CDT 2002

Thanks! 

But you misunderstanded the problem I meet.

The originally meaning I refered is how to change the options's value nor to change which one being selected.I find the solutions of the problem.

targetobj is the select object I want to change its options , the refereddata is an array to store the values I want to change to select object's options's text.

for (i = 0; i < refereddata.length; i++) {  
  var newOption = document.createElement("OPTION");
  newOption.text="refereddata[i]";
  newOption.value="i";                    
  targetobj.options[i] = new Option(newOption.text,newOption.value);  

} 
targetobj.length = i;

  here is an example:

  <html>
  <head>
  <script type="text/javascript">
   function testing ()
   {
    myCombo.selectedIndex = 4;
   }
  </script>
  </head>
  <body>
   <center>
    <button onclick="testing ();">just testing</button>
    <select id="myCombo">
     <option>zero</option>
     <option selected>one</option>
     <option>two</option>
     <option>three</option>
     <option>four</option>
     <option>five</option>
    </select>
   </center>
  </body>
  </html>

  If you want more about HTML "select" object, look on the documentation (this is for IE):
