HttpCapabilitiesBase.JavaScript Property

Note: This API is now obsolete.

Gets a value indicating whether the browser supports JavaScript.

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

[ObsoleteAttribute("The recommended alternative is the EcmaScriptVersion property. A Major version value greater than or equal to 1 implies JavaScript support. http://go.microsoft.com/fwlink/?linkid=14202")]
public bool JavaScript { get; }

Property Value

Type: System.Boolean
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.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
    void Page_Load(Object Sender, EventArgs e)
    {
        CheckBrowserCaps();
    }

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

        Label1.Text = labelText;
    }
</script>
