how to get applicationpath from masterpage code page?

Question

If it is a normal page I can use

public static string GetRootPathJS(Page page)
{
    StringBuilder strBuilder = new StringBuilder();

    string strApp = page.Request.ApplicationPath;
    if (strApp == "/") strApp = "";

    strBuilder.Append("<script type='text/javascript'>");
    strBuilder.AppendFormat("rootPath=\"" + strApp + "\";");
    strBuilder.Append("</script>");

    return strBuilder.ToString();
}

In pageonload method just call

ClientScript.RegisterStartupScript(this.GetType(), "root", GetRootPathJS(this));

After this I can call rootPath directly in client side using javascript. But in masterpage code page there is no ClientScript reference. How to get rootpath in masterpage code page. I also tried to get rootpath from children page, however, the javascript in masterpage can not find rootpath defined in children page.

Answer 1

If I understand your question correctly your trying to get the root path in Javascript?

If so you can use the following on the masterpage.master

<script type="text/javascript">
    var baseUrl = '<%=Page.ResolveUrl("~")%>';
</script>
