javascript variable in asp 1

[Papa Bear]

Hi All

I have the following script in an ASP page which is activated by a button onclick.

function Updatedate(var1,var2) {
    var D1 = Date.parseExact(document.getElementById("DateID"+var1).value,"d/M/yyyy");
    var n = <%=sysRS("gap"+var1)%>;
    var D2 = D1.addWeeks(n);
    var D3 = D2.toString("dd/MM/yyyy")
    document.getElementById("DateID"+var2).value = D3;
}

I just can not get the right format for the line starting "var n ="

If I change it to

    var n = <%=sysRS("gap1")%>;

it works, but I want to be able to change the 1 to the value held in var1 which will be 1 to 4.

Any ideas please

The problem that you have here is

1) The <% .. %> part is done first at the server end

2) var1 is only known at runtime so it cannot be passed to the server

One way around it would be to use a switch statement. Something like

var n;
switch (var1)
{
case 1:
   n = <% sysRS("gap1") %>;
   break; 
case 2:
   n = <% sysRS("gap2") %>;
   break; 
   ...
}

It is tedious but it will work.

Thanks for that. Worked a treat. Do I need to close this thread? If so, how.

No need to close the thread. I think it gets automatically closed after a few months. Thanks for the star.
