When the same request multiple jsonp, browser through a window[jsonpCallback] not defined.

First, I do not define the window[jsonpCallback] function, jQuery will define it. But when the same request multiple jsonp, the browser through a error window[jsonpCallback] not defined. I test it from v1.5.2 to v1.7.1.

!#javascript
$.ajax({
    type: 'get',
    dataType: 'jsonp',
    data: 'query=' + encodeURIComponent(v),
    jsonp: 'callback',
    jsonpCallback: 'docallback',
    cache: true,
    url: 'http://abcd.com/e.php',
    success: function (data) {
        //do something        
    }
});

So I had to this way fix it.

window[jsonpCallback] = function () {};

window[jsonpCallback] = function () {};

You'd set your testcase to use jQuery 1.5.2. When I set it to jQuery 1.7.1, I didn't get any error.

Thanks. But, " i != data.i" . I think the correct result should be "i === data.i".
