[SOLVED] When selecting from dropdown list automatically recalculates. How?

[ghurty]

Hi

I am pretty new to php coding so please bear with me.

I have a drop down list of locations, and then I have a calculate button to refresh the page using the new location.

How can I have it that as soon as you click on a location, it recalculates, and that you dont need to click on the calculate button at all?

 

Thanks

 

<form name="mainform" action="index.php" method="get">
<input type="hidden" name="option" value="com_luach" />
<select name="activelocation">
<?php fillLocationList($activelocation); ?>
</select>
<input name="Submit" type="submit" value="Calculate">

Thanks

Ajax is an advanced topic. It's also not really a topic for this forum. Check out the javascript forum on this site... they should be able to help.

You just want to submit the form when someone selects an option in the dropdown menu yeah?

 

<select name="activelocation" onchange="this.submit();">

 

 

Why bring ajax into this at all?

Maybe I misunderstood what was being asked. I thought he wanted to know how when you selected say a country all the states that belong to it become listed in another drop down.
