)

Parameters

Return Value

Type: System.Web.Mvc.JavaScriptResult
The JavaScriptResult object that writes the script to the response.

This method is used to send JavaScript code that is created on the server to the client. The JavaScript is automatically run on the client. The result object that is prepared by this method is written to the response by the MVC framework when the object is executed.

The following example shows how to send jQuery code from the server to the client. The script runs immediately when the client receives it. When the "Test JavaScript" link is selected, the jQuery client script is sent to the browser and the browser displays "JavaScript Passed".

<i><b>JavaScript Passed</b></i> will appear on the next line 
    when you click the <b>Test JavaScript</b> link.<br />
       <div id="divResultText"></div>
  <%= Ajax.ActionLink("Test JavaScript", "TestJavaScript", 
      new AjaxOptions{UpdateTargetId = "divResultText"}) %>
public ActionResult TestJavaScript() {
    string s = "$('#divResultText').html('JavaScript Passed');";
    return JavaScript(s);
}
Public Function TestJavaScript() As ActionResult 
    Dim s As String = "$('#divResultText').html('JavaScript Passed');" 
    Return JavaScript(s) 
End Function
