Gets a value indicating whether the browser supports JavaScript.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)

public bool JavaScript { get; }

Property Value

true if the browser supports JavaScript; otherwise, false. The default is false.

If the browser supports JavaScript but scripting is disabled through a security setting, the JavaScript property will return true but script will not execute on the browser.

The following code example shows how to determine whether the browser supports JavaScript.

<%@ page language="C#"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<script runat="server">
    void Page_Load(Object Sender, EventArgs e)

    void CheckBrowserCaps()
        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).JavaScript)
            labelText = "Browser supports JavaScript.";
            labelText = "Browser does not support JavaScript.";

        Label1.Text = labelText;

<html xmlns="" >
    <title>Browser Capabilities Sample</title>
    <form runat="server" id="form1">
            Browser Capabilities:
            <p/><asp:Label ID="Label1" Runat="server" />
