I tried this, but it didn't work. I need the value inside the form still
because the value of the select will be written to an array that gets passed
to the next page (as hidden inputs), which will in turn be compiled into a
value list for a db query. I tried making the name of the select be the
array posistion (value[7] in this case), but when I changed values, IE
errored and said that value.7 isn't an object. If I don't change the
option, ie, I use the default select value, the code works. But as soon as
I change the option, IE gives me an error and can't change the value. Would
this work: make the onChange event trigger a page refresh to set the form
values? Or will that simply draw the page again? Thanks.
Here is the code I'm using...all of the php variables have values that work,
the problem is in changing the value of the select
-----BEGIN--------
<script>
<!--
function changeValue(newValue) {
document.addstuff.value[7].value = newValue;
}
file://-->
</script>
echo "<td colspan=\"$numfields\"> Select which location you want this to
apply to.<br><select name=\"pickloc\"
onChange=\"changeValue(this.options[this.selectedIndex].value);\">";
$i=0;
while ($locidval = mysql_fetch_object($locinfo)){
echo "<option value=\"$locidval->LocationID\">Location:
$locidval->Area</option><br>\n";
}//end while
echo "</td></select><input type=\"hidden\"
name=\"value[$locidnum]\"></tr><tr>\n";
------END-----------
