Client-side & server-side javascript

Hi all,

I need a help desperately.
what I have been trying to do is in user control (mycontrol.ascx) I would like to validate dropdownlist using client-side javascript(not server side)

so what I did was

<SCRIPT>
function validate_form_step2()
{
val selectedval = document.forms (0).mydropdown.selectedIndex;
alert(selectedval);
}
</script>

but it didn't show any value and keeping saying error occured.

and also in seperate page
when I open a popup windows in user control and when I close the popup windows I would like to refresh the parent windows so I did like

<a href="" onclick="javascript: opener.location.refresh();"> somebutton </a>

But it doesn't refresh it.
what could be wrong?

Looking forward to hearing from you guys,

Good day!!

Try:
<a href="" onclick="javascript: window.opener.location.reload();"> somebutton </a>

To answer your first part - Javascript refers to array elements with square [] brackets. (Most languages do - ASP/VB bad!)

Also, the SELECT list property .selectedIndex will only get the options selected index (!) - not the value. To get the value:

document.forms[0].mydropdown.options[document.forms[0].mydropdown.selectedIndex].value

It's got to be the most verbose bit of code around.

PS - there is a forum specifically for JS now

Thanks,

but my real problem is (sorry, reload works fine by the way)
say you open a web form which contains a web user control and through that user control you create a popup windows which has a textbox.

Basically, I would like to send whatever value in the textbox in the popup windows to the textbox in the web user control using javascript.

something like this

window.opener.webformForm1.web_user_control_textbo x1.value = document.popupForm1.textbox1.value

if you use this javascript for php or asp it should work however, since I am using web user control, it seems to work in a different way

Any Idea guys!!

You're getting confused between server-side and client side. You can't pass values between windows dynamically like you're talking about with a server-side language like ASP or PHP.

Using JS, you'd do something like:

window.opener.webformForm1.textbox1.value = document.forms[0].textbox1.value
