View Full Version : Use Drop down menu w/ description to populate hidden variable

04-09-2010, 07:08 PM
1) Script Title:
Drop down menu w/ description

2) Script URL (on DD):

3) Describe problem:

I found this script, and it does most of what I want; but rather than display the value for a selection in a pulldown, I want to assign that value to a hidden variable.

So if a user picks a product from the menu, I want to set a hidden variable's value (email address chosen from the specified array.)

Can I do this?

Just wanted to clarify a bit...in my particular case, the user is selecting a product from the menu.

Rather than display the text from the array associated with that selection, I want to assign the array element's value to a hidden variable ('assigned_to').

BTW, I took out the 'onClick' code, as I just want the onChange behavior, and have a separate submit button.

Hope someone can help.... :)

<!--Example drop down menu 1-->

<form name="form1">
<select name="select1" size="1" style="background-color:#FFFFD7" onChange="displaydesc(document.form1.select1, thetext1, 'textcontainer1')">
<option selected value="product-1">Product 1</option>
<option value="product-2">Product 2</option>
<option value="product-3">Product 3</option>
<option value="product-4">Product 4</option>
<option value="product-5">Product 5</option>
<span id="textcontainer1" align="left" style="font:italic 13px Arial">
<input type="hidden" name="assigned_to" value="" />


<!--Example drop down menu 2-->

<form name="form2">
<select name="select2" size="1" style="background-color:#E3FFDF" onChange="displaydesc(document.form2.select2, thetext2, 'textcontainer2')">
<option selected value="http://www.cnn.com">CNN</option>
<option value="http://www.msnbc.com">MSNBC</option>
<option value="http://news.bbc.co.uk">BBC News</option>
<option value="http://www.theregister.com/">The Register</option>
<input type="button" value="Go"
<span id="textcontainer2" align="left" style="font:italic 13px Arial">

//2) Call function displaydesc() for each drop down menu you have on the page
// This function displays the initial description for the selected menu item
// displaydesc(name of select menu, name of corresponding text array, ID of SPAN container tag):

displaydesc(document.form1.select1, thetext1, 'textcontainer1')
