javascript - JSON.解析: why this doesn't work

Question

我得到了一个 JSON :

$.ajax({
        type: "POST",
        url: myUrl,
        success: function (result) {
             var data = JSON.parse(result);
             for (var i = 0; i < data.poles.length; i++) {
             ....

我在调试器中看到的是:

data = "{"poles":[{"id":36,"name":"AUVERGNE"},{"id":44,"name":"Alsace"},{"id":42,"name":"Artois"},....],"poleNumber":48}

但是我收到一条消息，说 data.poles 未定义

我想念什么？

Answer 1

Json还好吗？

{"poles":[{"id":36,"name":"AUVERGNE"},{"id":44,"name":"Alsace"},{"id":42,"name":"Artois"}],"poleNumber":48}

编辑:

好的，如果你有这个 JSON:

data = {"poles":[{"id":36,"name":"AUVERGNE"},{"id":44,"name":"Alsace"},{"id":42,"name":"Artois"}],"poleNumber":48}

你可以完美地制作data.poles。删除第一个“，你有一个错误的json，所以你永远不会解析

"{"poles":[{"id":36,"name":"AUVERGNE"},{"id":44,"name":"Alsace"},{"id":42,"name":"Artois"}],"poleNumber":48}
