Onclick in select not working in IE

Question

Am a bit new to javascript. This question might sound a bit too silly, but I'm not able to figure it out why the following doesn't work in IE and works in firefox..

<select multiple="multiple">
 <option value="tx" onClick="alert('tx');">Texas</option>
 <option value="ak" onClick="alert('ak');">Alaska</option>
 <option value="ca" onClick="alert('ca');">California</option>
 <option value="ws" onClick="alert('ws');">Washington</option>
 <option value="tn" onClick="alert('tn');">Tennessee</option>
</select>

The alert doesn't come up in IE (I'm using IE8). But it works in firefox!!!!!

Answer 1

According to w3schools, the option tag does support an onclick attribute. I tried with with bottom of the barrel IE6 and this doesn't seem to be the case.

The simplest way to do this would be:

<select multiple="multiple" onchange="alert(this.value);">
 <option value="tx">Texas</option>
 <option value="ak">Alaska</option>
 <option value="ca">California</option>
 <option value="ws">Washington</option>
 <option value="tn">Tennessee</option>
</select>

This is not exactly what you are after, but should be pretty close.

It would just take more work:

<select multiple="multiple" onchange="
    switch (this.value){
      case 'tx': funcOne(); break;
      case 'ak': funcTwo(); break;
      etc...
   }
 ">
 <option value="tx">Texas</option>
 <option value="ak">Alaska</option>
 <option value="ca">California</option>
 <option value="ws">Washington</option>
 <option value="tn">Tennessee</option>
</select>

At this point it would be appropriate to wrap the onchange into a function in a js file instead of embedding it in the html.

Answer 2

I would use the onchange event:

<select multiple="multiple" onchange="alert(this.options[this.selectedIndex].value)">
 <option value="tx">Texas</option>
 <option value="ak">Alaska</option>
 <option value="ca">California</option>
 <option value="ws">Washington</option>
 <option value="tn">Tennessee</option>
</select>

Although Daniel Mendel's solution is perfectly valid.

Answer 3

This is because IE doesn't register a click event when you select a new option in a select field (guessing). Instead, you should use the onBlur event (and put the code into your javascript instead) like so (assuming jQuery):

<script type='text/javascript'>
  $(document).ready(function(){
    $('select#state').bind('blur', function(){
      alert(this.val());
    });
  });
</script>

<select id='state' multiple="multiple">
  <option value="tx">Texas</option>
  <option value="ak">Alaska</option>
  <option value="ca">California</option>
  <option value="ws">Washington</option>
  <option value="tn">Tennessee</option>
</select>
