我的 JSONP 调用在 MSIE7 中出现对象错误。我已经修复了我得到的 JSON 对象。（它之前没有引号之间的键值）有了这个我认为我已经修复了它，因为它确实可以从静态文件中工作。但是，当我开始工作并再次对其进行测试时，它再次返回了对象错误。

我也尝试使用普通 &.getJSON(url, callback) 并添加了 ?callback=? 到网址，但无济于事

这是调用本身：

$.ajax({
  type:'GET',
  url: url,
  error:function (xhr, ajaxOptions, thrownError) {
alert(xhr.statusText);
alert(xhr.responseText);
alert(xhr.status);
alert(ajaxOptions);
alert(url);
alert(thrownError);
  },
  success:successHandler,
  dataType:'jsonp',
  jsonp:'_jsonp',
  jsonpCallback:'jsonpCallback',
  cache:true
});

和 json-object 的片段

jsonpCallback({"positionInfoContainer":[{

}]
});

当我使用静态文件而不是 dataType:"jsonp" - dataType:"text json" 并将 jsonp 和 jsonpCallback 注释掉时，此代码段有效。

此代码在 Opera、Chrome 和 Firefox 中完美运行。（虽然所有最新版本）
