IE中的合法JSON提供错误:预期标识符、字符串或数字

Question

我有一个奇怪的IE错误，我在google上唯一能找到的就是，当你在字典或数组中有一个后缀逗号时，这个错误就会出现。但根据JSONLint的说法，我的JSON是非常出色的，所以我感到非常沮丧。JSON在这里列出。我的问题是。有没有人经历过这个错误，而不是"，"-related？任何帮助或指导都会得到极大的认可。

顺便说一下，错误出现在我尝试过的任何JSON解码器中，但我想使用的是mootools JSON.decode

更新

伙计们..。我已经解决了我的问题。我得到json的方式来自Django，我假设我可以简单地获取我的字典的simplejson.dump，然后在这样的模板中使用它：

var opf = {{ var }}

这在webkit和mozilla浏览器中运行得很好，但是IE在这条线上的神秘错误让IE窒息了。所以..。我试过的是

var opf = JSON.decode({{var}});

和

var opf = JSON.decode("{{var}}");

这产生了完全相同的错误，但是现在这个错误发生在mootools的某个地方。我什么都试过了。/因此，我最终所做的是创建一个Request.JSON，这样我就不会将变量传递给模板。现在，IE突然发挥得很好:/我觉得这是个小问题，但到底是怎么回事。谢谢你的快速回复伙计们。

最新答案

我认为这一定是页面其他地方的错误。Dimitar在下面指出，您标记了您的问题mootools，因此可能正在使用JSON.decode，但效果很好：

var obj, json;
json = '...your JSON...';
obj = JSON.decode(json);

实例化

交替：如果引用的内容实际上出现在JavaScript代码中(没有包含在字符串中，没有通过XHR或其他方式从服务器加载)，那么您引用的是一个JavaScript对象文本，而不是JSON，您根本不解析它。简化示例：

JavaScript对象文本：

var obj = {
    foo: "bar"
};

属性名称周围的引号在对象文本中是可选的(在JSON中不是这样，在JSON中它们是必需的)，所以这也很好：

var obj = {
    "foo": "bar"
};

杰森：

var json = '{' +
           '   "foo": "bar"' +
           '}';
var obj = JSON.decode(json);

原始答案：(错过了mootools标签)

它可以很好地工作在json2.js上，甚至返回到IE6上：

var obj, json;
json = '...your JSON...';
obj = JSON.parse(json); // where `json` is a string containing your JSON

实例化

听起来像是如何解析它的问题，或者代码中其他地方的问题。

如果您使用的是原始eval，请确保将JSON包装在括号中：

var obj, json;
json = '...your JSON...';
obj = eval('(' + json + ')');

实例化

...but我不建议使用eval来解析JSON (甚至不建议使用json2，它在幕后使用eval )，除非您确定了源(例如，您自己的服务器)。我可能会使用来自Crockford的github页面的一个非Crockford的github页面解析器。
