dynamic dropdown updating textarea help

[ccrevcypsys]

Hello out there in php world.lol

ne ways i need help on figuring out how to make a dynamic text area.

What it needs to do is there is a select up above the text area and when someone selects something off of that drop down and they press add (or it just does it) then i need it to post in that textbox. But i am not smart enough to come up with logic that would work out. So this is what i have at the moment.

            <select name="addServ"><?php 
$query = "SELECT * FROM `serviceRequested`";
$result = mysql_query($query);
while ($service = mysql_fetch_array($result, MYSQL_ASSOC)){ ?>
		 <option value="<?php echo $service['id']; ?>"><?php echo $service['serviceName']; ?></option> 
		 <?php } ?></select> <a href='<?php echo "serviceOrder.php?p=so&"; ?>'>Add Item</a>
            <textarea name="servicerequested" disabled="disabled" class="textArea" cols="80" rows="10">
            
            </textarea>

give your select box and textarea unique ids

 

add a load event to the window that will call a function to listen to a change in the select box

 

window.onload = function(){

var sel_box = document.getElemetById('select_box_id');

var tex_are = document.getElemetById('text_area_id');

 

sel_box.onchange = function(){

tex_are.value += 'whaver you want to add';

}

};
