Question

jQuery getJSON中的回调函数永远不会在Internet Explorer 9中被调用，尽管所请求的文件已成功加载（我已在“网络”选项卡中检查过）。

var user = 1;

$.ajaxSetup ({
    cache: false
});

var fileUrl = "/path/to/file.php";

var fetchQuestions = function(kanji)
{    
    alert('this fires');
    $.getJSON(
        fileUrl,
        {action: "get-q", kanji: kanji, user: user},
        function(json)
        {
            alert('this does not fire');
            questions = json;
            currentItem = json.info.kanji;
            showStart(json.info);
        }
    );
};

返回的数据是有效的json
它适用于所有其他浏览器
所请求的文件确实加载了200 OK和Content-Type application / json
文件中的任何位置都没有console.log（）调用
控制台中没有错误（在IE9或任何其他浏览器中）

有什么想法吗？

这是返回的JSON：

                "kanji": "線",
                "meanings": "line",
                "desc": "",

Answer 1

json_encode'返回JSON的“已知”部分解决了这个问题！看起来IE在unicode字符方面存在一些问题。

IE9中没有执行getJSON回调
