I have come up with a solution based on my understanding of your requirement. Here it is:

JAVA SCRIPT:


Please note that in the tag I have used onChange. I tried with onClick but it causes problem in IE. On IE (if used onClick) it does not output the first selection. But works perfectly fine on Firefox. onChange works perfect for both browsers.

Hope this helps.

Thank you.

Hello,
First of all, you have made a wrong method. When dealing with "textbox" control on the page, you would need to use the .value attribute to change the contents of it...

Plus, when dealing with drop down control, remember, all the items in that drop down acts as an array.

So do something like this:

A
B
C


So once you change the element on that Dropdown, it will activate the chkval method. Now to parse the input You would need to access the options DOM and grab the selected index like the following:
var value = mval.options[mval.selectedIndex].value;

The whole script looks like this if you want to try it out

index.html
===========================================

A
B
C

===========================================

I hope I helped,
Good Luck
