Question

suppose i wrote my javascript in my aspx page like below

<script type="text/javascript">
function pop() {
    // test 1

    /*  test1
        test2
        test3
    */
     myfunc1();
     myfunc1();
     myfunc1();
}

now at runtime i want to remove all javascript comment from the page using regex from render method of the page. so just tell me what regex i need to use.

protected override void Render(HtmlTextWriter writer)
    {
        using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new System.IO.StringWriter()))
        {
            base.Render(htmlwriter);
            string html = htmlwriter.InnerWriter.ToString();

            if ((ConfigurationManager.AppSettings.Get("RemoveWhitespace") + string.Empty).Equals("true", StringComparison.OrdinalIgnoreCase))
            {

                // regex for removing html comment
                html = Regex.Replace(html, @"((<!-- )((?!<!-- ).)*( -->))(\r\n)*", String.Empty);
                // regex for removing line break & carriage return
                html = html.Replace(";\r\n", ";");
            }
            writer.Write(html.Trim());
        }
    }
