Re: Javascript help
Here is something I typed up real fast.
In the <head> section of your page Code:
<script type="text/javascript">
<!--
var descriptions = new Array(5);
descriptions[0] = "Description 1";
descriptions[1] = "Description 2";
descriptions[2] = "Description 3";
descriptions[3] = "Description 4";
descriptions[4] = "Description 5";
function listChanged(obj) {
var curIndex = obj.selectedIndex;
var curValue = obj.options[curIndex].value;
if(Number(curValue).toString() != 'NaN' || Number(curValue) < 0) { // make sure it's a valid number
document.getElementById('output').innerHTML = descriptions[curValue];
} else {
document.getElementById('output').innerHTML = "Please select an item to view it's description.";
} // end if/else
} // end function
//-->
</script>
Code:
<select id="itemSelection" name="itemSelection" onchange="listChanged(this);"> <option value="-1" selected>--Select--</option> <option value="0">First Item</option> <option value="1">Second Item</option> <option value="2">Third Item</option> <option value="3">Fourth Item</option> <option value="4">Fifth Item</option> </select> </form> <div id="output"> Please select an item to view it's description. </div> You can change the text for each of the descriptions and this will be updated when they change options. If you can provide a little more information about what you're trying to do, I can help with the second script also.
