Compilation error - user control

[Zeba]

Hi,

I have a user control in which in have the following code :


<%@ Control Language="C#" AutoEventWireup ="true"
CodeFile="Ratin gControl.ascx.c s" Inherits="UserC ontrols_RatingC ontrol"
%>
<script type="text/javascript">

function alterRating(rat ing)
{
var i;
var img = document.getEle mentById("<%=st ar"+i+".ClientI D %>");
for(i=1;i<=rati ng;i++)
{
var img = document.getEle mentById("<%=st ar"+i+".ClientI D %>");
img.src = "~/Images/StarOver.gif";
}
for(i=rating;i< =5;i++)
{
var img = document.getEle mentById("<%=st ar"+i+".ClientI D %>");
img.src = "~/Images/StarOff.gif";
}
}


I'm getting a compilation error that says :

) expected

Line 11: var img = document.getEle mentById("<%=st ar"+i+".ClientI D
%>");

What is the problem ??

Thanks !!

It's not clear to me what you're trying to do. What do you want the
processed script to come out as? Bear in mind that "i" here is a
variable in the JavaScript, not in the .NET code.

(You might get more replies in the ASP.NET group, by the way.)

Re: Compilation error - user control

If I can guess what you are trying to do...
first of all, your i that you have within the <%= %brackets is going
to refer to your codebehind variables (Not the javascript variable).
It almost seems like you are trying to use reflection or something and
get the ClientID of that item

First of all your javascript is referring to the variable i right
after you declare it but it has no value yet!

Maybe you could use an alternative approach of writing this in your
code behind

WriteScript() //Rough C# Code
{
int i;
HtmlControl img; // = Page.FindContro l("star"+i); // i not
declared yet
for(i=1;i<=rati ng;i++)
{
img = Page.FindContro l("star"+i);
img.src = "~/Images/StarOver.gif";
}
for(i=rating;i< =5;i++)
{
// same thing here
// var img = document.getEle mentById("<%=st ar"+i+".ClientI D
%>");
// img.src = "~/Images/StarOff.gif";
}

}

// same thing here
// var img = document.getEle mentById("<%=st ar"+i+".ClientI D %>");

tada..

Or if you want to do it from javascript not codebehind, just modify
the above to do the following

REsponse.write( "<script type='text/javascript'>");
then in the loop you can stick another Response.Write( ...)
then end with Response.Write( "</script>")

or alternatively, read about RegisterClientS cript Here:
