    I need a piece of javascript that will hide OR show a text box IF a certain thing is selected from the dropdown.



    DROPDOWN:
    
<select name="stuff" class="textField">

    <option value="" selected="selected" class="textField">-select one-</option>
   
  <option value="1" <? if($starts==1){echo"selected";}?>>one </option>

    <option value="2" <? if($starts==2){echo"selected";}?>>two</option>


  </select>
    HTML:
    When option "2" is selected a text box needs to appear next to the dropdown

    <input name="anotherthing" type="text" class="box" value="" />
    HTML:
    Can it be done?

    I've done it!
    Found this 
    <script type="text/javascript"> 
function toggleField(val) { 
var o = document.getElementById('other'); 
(parseInt(val) == 99)? o.style.display = 'block' : o.style.display = 'none'; 
} 
</script> 

and the form: 


<form action="" method="post"> 
<select name="sel" id="sel" onChange="toggleField(this.value);"> 
<option value="0">Select</option> 
<option value="1">One</option> 
<option value="2">Two</option> 
<option value="99">Other</option> 
</select> 
<input type="text" name="other" id="other" style="display: none;"> 
</form>
