迭代JSON列表会导致“错误：语法错误，无法识别的表达式”

I have an AJAX call, which calls a controller. This controller returns the following JSON:

我有一个AJAX调用，它调用一个控制器。该控制器返回以下JSON：

{"officeProducts":"[{\"Id\":96,\"MyProperty\":null,\"Enabled\":true,\"Envelope\":{\"Id\":1,\"Quality\":\"God\",\"PaperSize\":\"A4\",\"Type\":\"Window\"}},{\"Id\":169,\"MyProperty\":null,\"Enabled\":true,\"Envelope\":{\"Id\":1,\"Quality\":\"God\",\"PaperSize\":\"A4\",\"Type\":\"Window\"}},{\"Id\":174,\"MyProperty\":null,\"Enabled\":true,\"Envelope\":{\"Id\":1,\"Quality\":\"God\",\"PaperSize\":\"A4\",\"Type\":\"Window\"}},{\"Id\":175,\"MyProperty\":null,\"Enabled\":true,\"Envelope\":{\"Id\":1,\"Quality\":\"God\",\"PaperSize\":\"A4\",\"Type\":\"Window\"}}]"}

And now I want to iterate the list. So I basically want to iterate the officeProducts.

现在我想迭代列表。所以我基本上想要迭代officeProducts。

I have the following code, where I obviously do something wrong, as I get a:

我有以下代码，我显然做错了什么，因为我得到了：

Error:

错误：

Error: Syntax error, unrecognized expression: [{"Id":96,"MyProperty":null,"Enabled":true,"Envelope":{"Id":1,"Quality":"God","PaperSize":"A4","Type":"Window"}},{"Id":169,"MyProperty":null,"Enabled":true,"Envelope":{"Id":1,"Quality":"God","PaperSize":"A4","Type":"Window"}},{"Id":174,"MyProperty":null,"Enabled":true,"Envelope":{"Id":1,"Quality":"God","PaperSize":"A4","Type":"Window"}},{"Id":175,"MyProperty":null,"Enabled":true,"Envelope":{"Id":1,"Quality":"God","PaperSize":"A4","Type":"Window"}}]

My AJAX call:

我的AJAX电话：

self.updateOfficeProducts = function() {
    $.ajax({
        url: '/SingleLetter/GetOfficeProducts',
        type: 'POST',
        data: {
            'country': self.countryId
        },
        dataType: 'json',
        success: function (data) {
            console.log(data.officeProducts);

            $(data.officeProducts).each(function (index, ele) {
               alert(ele.Id);
            });
        }
    });
};

So I would expect to iterate 4 different objects, where I can say things like ele.Id or ele.Enabled. Instead I get my syntax error.

所以我希望迭代4个不同的对象，我可以说ele.Id或ele.Enabled之类的东西。相反，我得到了我的语法错误。

What am I doing wrong? :-) Obviously some syntax thing.

我究竟做错了什么？ :-)显然有些语法的东西。

Use JSON.parse-

使用JSON.parse-

success: function (data) {
    data = JSON.parse(data);
    $(data.officeProducts).each(function (index, ele) {
       alert(ele.Id);
    });
    ...

Another thing — I'm not sure of .NET, but the response you're getting back is not of the form expected by ajax. The string is not properly json-encoded.

另一件事 - 我不确定.NET，但你回复的反应不是ajax预期的形式。该字符串未正确进行json编码。

You have to remove " before and after the [ and ], so the string would be-

你必须删除“[和]之前和之后，所以字符串将是 -

var a = '{"officeProducts": [{\"Id\":96,\"MyProperty\":null,\"Enabled\":true,\"Envelope\":{\"Id\":1,\"Quality\":\"God\",\"PaperSize\":\"A4\",\"Type\":\"Window\"}}] }';
//                         ^here                                                                                                                           and here^
