ASP.NET MVC Javascript ActionResult

Question

Anyone have any examples of javascript actionresults? I am having a hard time getting the script to execute once it has been returned. Thanks

Answer 1

This might work..

 public ActionResult Search(string name)
    {
        // var someScript = Server.HtmlEncode("<script>alert('Hello')</script>");

        return  Content("<script>alert('Hello')</script>" );
    }

Answer 2

Here's an example I found on a blog post, which actually describes it as an anti-pattern, because the Controller has to have in-depth knowledge of the View in order to function.

public ActionResult DoSomething() {   
    string s = "$('#some-div').html('Updated!');";   
    return JavaScript(s);   
}  

Answer 3

The only way I have found to return a JavascriptResult and execute it on the client is with JQuery:

<script>
$(document).ready(function () {
    $("button").click(function () {
        $.getScript("/Home/ShowAlert");
    });
});
</script>

<button>Use Ajax to get and then run a JavaScript</button>

In the controller:

public JavaScriptResult ShowAlert() {
        var script = "alert('Hello');";
        return new JavaScriptResult() { Script = script };
}
