I suggest you provide your service using JSONP instead of ad hoc JavaScript
code. That way it will work with the native JSONP support in jQuery and
other libraries.
To do this, you need to accept a parameter in your service URL that
specifies a callback function name, and you generate the output using that
name as a JavaScript function call. For example, suppose you use callback=
for this, and format=jsonp to specify the JSONP output. (This way you could
offer additional formats such as XML or straight JSON if you want.)
Then the jQuery code might look like:
$.getJSON(
'http://example.com/service?format=json&callback=?',
function( json ) {
alert( json.test );
}
);
jQuery will replace the ? at the end of that URL with a generated function
name, so the final URL might look like:
http://example.com/service?format=json&callback=json1234
And the data you return would look like:
json1234({"test":"abc"})
