[solved] don't understand javascript variable scope; now talking about validation plugin

[quote author="noctrum" date="1295986631"]move the result declaration outside of the function.

Code:

var result = false;
function name_free(value, element) {
    if(something) {
        $.post('something', { foo: bar }, function(data) {
            if(data == 'true') result = true;
        }
    }
    console.log(result);
    return result;
}

That way false is returned every time, since return result; will be called before result can be set to true by $.post.

You should move whatever you want to do with result to within the callback function!
