AJAX toolkit - webservice execution issue

Question

It's hard for me to understand what is happening here. I am trying to copy some javascript onClick for a button in a Force.com list view for a custom object. Here is js.

{!REQUIRESCRIPT("/soap/ajax/15.0/apex.js")}
{!REQUIRESCRIPT("/soap/ajax/15.0/connection.js")}


var myURL = sforce.apex.execute("MyWebServices", "myUrl", {});

and here is the web service I'm trying to call.

global class MyWebServices {

    webservice static String myUrl(){
    return 'www.foo.com';
    }

}

When I click the button, I get a small pop-up warning:

"Problem with JavaScript OnClick for this button or link: Unable to call the 'execute' method from undefined." When I repeat the sforce members, there is no "vertex".

}

Answer 3

The “connection” must be indicated to the “top”. It installs the main sforce object.
