View Full Version : Problem client - server / ASP vs. Javascript

I have a problem wich I think it has to do with client - server. I'am writing a page with ASP. I'am writing back some data in selection fields.
With Javascript function I assign the value to 'IFOR_Attr_1':

document.all['IFOR_Attr_1'].value = TTTEXT_IFOR_array[selindex-1];
alert("If-waarde parm Field: " + Field + " waarde parm IFOR_Field: " + document.all['IFOR_Attr_1'].value);

With the alert I see the value of 'IFOR_Attr_1' is 1. this is correct.

But further in the code I need this value with a ASP request on IFOR_Attr_1 like:

Call displaytext("Attr_1 " + Request("IFOR_Attr_1"))
Call WriteKenmerkenCriteria("Attr_W1", Request("IFOR_Attr_1"), Request("CHAR_Attr_1"))

But now is the value of IFOR_Attr_1 empty. At least not 1.
My conclusion is that the value for IFOR_Attr_1 is at the client side changed but not at the server side?

How can I solve this?

Anyway is it possible to assign a value to a ASP variable with javasript code like:

Dim Aspvar
Aspvar = javascript:function()

Thanks in advanced,

The asp code is processed long before the javascript is even written out. Server side code is always executed before client side code is. If you need to alter a value using clientside coding, then you need to submit the page afterwards for the server to see the alteration.
