Forum: Rails Spinoffs (closed, excessive spam) getting AJAX/JSON into global var

I want to have a global object that can be updated via Ajax:

var globalObject;

function updateObject (id) {
 new Ajax.Request('url', { parameters: {id: id}, onSuccess:
function(transport) {
globalObject = transport.responseText.evalJSON();
}});
}

That never seems to work though, why not?

Thanks!

That should actually work unless there's another "globalObject" in the
scope of callback function. Are you sure a proper response comes from
the server?

When are you verifying its value, it will be undefined until the ajax
request has come back to the onSuccess handler.
