And remember that Javascript is case-sensitive, so &quot;.Length&quot; should be &quot;.length&quot; and &quot;.Options(i)&quot; should be &quot;.options&quot;.<br />
<br />
Also, if you are trying to compare to see if two values are equal, it should be &quot;==&quot; instead of &quot;=&quot;
</div>


And remember that Javascript is case-sensitive, so ".Length" should be ".length" and ".Options(i)" should be ".options".

Also, if you are trying to compare to see if two values are equal, it should be "==" instead of "="

Getting Selected Listbox Items in Javascript

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
