jQuery.ajax 成功回调函数未执行 [英] jQuery.ajax success callback function not executed

问题描述

我有一个 JavaScript Ajax 调用 (jQuery.ajax)，它不执行成功回调函数.

I have a JavaScript Ajax call (jQuery.ajax), that does not execute the success callback function.

$.ajax({
        url: target,
        contentType: 'application/json; charset=utf-8',
        type: 'POST',
        // type: 'GET',
        dataType: 'jsonp',
        error: function (xhr, status) {
            alert(status);
        },
        success: function (result) {
            alert("Callback done!");
            // grid.dataBind(result.results);
            // grid.dataBind(result);
        }
    });

我在萤火虫中看到，请求已发布，并按预期返回了 json 方面的正确结果.怎么了?

I see in firebug, that the request is posted and the correct result in terms of the json is returned as expected. What is wrong?

推荐答案

很多时候我都遇到过类似的问题，大部分是因为json格式错误.尝试以文本数据类型获取结果，看看这是否是您的问题.

For many times I have encountered similar problems and most of the time the reason was a malformed json. Try getting the result as text data type to see whether this is your problem.

另外，我想问一下您是否使用了像&jsoncallback=?"这样的参数在您的网址中，因为您的数据类型是 jsonp 而不是简单的 json.

Also, I'd like to ask if you're using a parameter like "&jsoncallback=?" in your url, since your data type is jsonp instead of simple json.
