javascript - How to change a field based on user's selection in an HTML select? -

-

i have select list containing variables query 

<tr>   <td>county name:</td>     <td>       <select name="countyname" onchange="countyid.value = countyname.value">                 <option>select county</option>         <cfloop query = "getcounties">         <option value="#countyname#" >#countyname#&nbsp;&nbsp;&nbsp;#countyid#</option>         </cfloop>     </select>     </td> </tr>

how can populate county id field? 

<tr>   <td>county id:</td>     <td><input type="text" name="countyid">      </td> </tr>

i've never used jquery. there way use javascript? can see i've attempted javascript, can populate countyid countyname , need populated countyid.

breaking out function should work you: live example

<table>     <tbody>         <tr> <td>county id:</td> <td><input id="countyid" type="text" name="countyid"> </td> </tr>         <tr> <td>county name:</td>               <td>                  <select name="countyname" onchange="update(this)">                     <option>select county</option>                      <option value="1234">asdf</option>                      <option value="4321">asdf2</option>                  </select>              </td>         </tr>     </tbody> </table> <script>     function update( elem ) {     document.getelementbyid('countyid').value = elem.value;     } </script>

or in short change

this:

<select name="countyname" onchange="countyid.value = countyname.value">

to this, , should work

<select name="countyname" onchange="document.getelementbyid('countyid').value = this.value">

you need reference dom elements via document.getelementbyid() , not id alone
