[RESOLVED] PHP/ Javascript Dropdown box help

[markfc]

Hi Everyone.

I need a little help with some code on a php form. I think it's more javascript related but not sure.

I have a drop down box called say 'products' and next to it is a text box called 'other name'

The dropdown list has product names, product 1, product 2, product 3, and Other.

If a user chooses a product from this list I want it to copy the Product Name into the text box and make it readonly.

If they choose Other from the dropdown menu then I want them to be able to type in a product name in the text field.

Sounds simple but I really don't know where to start apart from using an onclick() on the drop down!

Thanks for any pointer you could give me!

Mark

Just need the box readonly unless they choose 'other'

doesn't seem to quite work at the moment.

<form name="ex" method="POST"><div align="center">
<select name="sel" size="1"
onchange="document.ex.selvalue.value = document.ex.sel.options[document.ex.sel.selectedIndex].text; if (document.ex.sel.selectedIndex==67) {document.ex.selvalue.disabled=true;}else{document.ex.selvalue.disabled=false;}">
<option value="100">full</option>
<option value="5">slight</option>
<option value="50">half</option>
<option value="67">Other - Please Specify</option>
</select>
<input type="text" name="selvalue" size="20"
</div></form>
