jQuery getJSON 中的回调函数在 Internet Explorer 9 中永远不会被调用，尽管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
- 它在所有其他浏览器中都能正常工作
- 请求的文件确实加载了 200 OK 和 Content-Type application/json
- 文件中的任何地方都没有 console.log() 调用
- 控制台中没有错误（在 IE9 或任何其他浏览器中）
有任何想法吗？
这是返回的 JSON：
