Question

I am working on Section 508 compliance for an existing application.

Now when I use http://achecker.ca/checker/index.php to test my page for Section 508 it shows “script must have a noscript section.” for the Ajax generated scripts.

How to get Ajax toolkit to have noscript tag appended after it generates the script on client side.

Answer 1

In Global.asax I have added below event and it worked like a charm

void Application_PostReleaseRequestState(object sender, EventArgs e)

{
    //add no script tag for 508 compatibility               
    if(Response.ContentType == "text/html")
    {
       //add no script tag for 508 compatibility
        Response.Filter = new NoScriptTagAppendFilter(Response.Filter);
    }        
}

public NoScriptTagAppendFilter(Stream stream)

{
    outputStream = stream;
}

public override void Write(byte[] buffer, int offset, int count)
{
    //base.Write(buffer, offset, count);
    string data = UTF8Encoding.UTF8.GetString(buffer);
    data = Regex.Replace(data, "</script>", "</script><noscript></noscript>");
    outputStream.Write(UTF8Encoding.UTF8.GetBytes(data), offset, UTF8Encoding.UTF8.GetByteCount(data));
    data = null;
}

This would definitely help someone in future who wants to 508 compatibility for script generated by Ajax & testing using http://achecker.ca/checker/index.php
