server side code

[mvmashraf]

In javascript I need assign value to the asp.net hidden field

I used like this
function set values()
{
document.getEle mentById('hf_Sa veChanges').val ue = "1";
}

But it shows error

Any suggetion would be appreciatable

Wouldn't be due to the fact that it is hidden? Is this server side code written to the client?

Try this Im sure this will work,

function set values()
{
document.getEle mentById('<%= hf_SaveChanges. ClientID%>').va lue = "1";
}

If you still get the error than plz specify what error are you getting.

I did the same like below
function GetCurrentFormC ontrolName(orig inalname)
{
var ctrllength=wind ow.document.all .length;
for(var count=0; count<ctrllengt h; count++)
{
var controlname=win dow.document.al l.item(count).i d;
var startindex = controlname.len gth - originalname.le ngth;
if(startindex < controlname.len gth && controlname.ind exOf(originalna me, startindex)!=-1)
{
return controlname;
}
}
}

function set()
{
var controlname = GetCurrentFormC ontrolName("hf_ SaveChanges");
var control = window.document .all.item(contr olname);

control.value=" 1";
}
