Javascript：解析JSON对象

-2

我想分析以下数据，这是来自服务器的对象列表。这是我有我的数据使用JSON.stringify(data.d);后：Javascript：解析JSON对象

"[{"__type":"EditGridDemo.CellData","empProperty":"SSN","empValue":"a","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Birth_Date","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Department_Name","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"email","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"First_Name","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Sex","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Strata_ID","empValue":null,"isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"SSN","empValue":"b","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Birth_Date","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Department_Name","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"email","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"First_Name","empValue":"","isValid":false,"comments":"Reason of what went wrong"},{"__type":"EditGridDemo.CellData","empProperty":"Sex","empValue":"","isValid":false,"comments":"Reason of what went wrong"},  
{"__type":"EditGridDemo.CellData","empProperty":"Strata_ID","empValue":null,"isValid":false,"comments":"Reason of what went wrong"}]"

这是CellData，其中包括列表empProperty，empValue，isValid方法，评价其attributes..I不能够访问这些属性JS。

解析它会对其进行字符串化。你为什么首先把它串起来？ – Quentin 2013-03-12 13:22:16

以前，我在做$ .parseJSON（data.d），它给了undefined .. – faizanjehangir 2013-03-12 13:23:28

你为什么要解析已经是JavaScript对象的东西？只需使用'data.d'。 – Quentin 2013-03-12 13:24:01

刚开始使用data.d [I] .empProperty并且如在一些评论提到data.d [I] .empValue i是阵列的索引。不要将它串起来，它已经被解析成了一个对象。

该结构是一个对象数组。所以，你可以简单地通过索引来访问每个元素：

var arr = JSON.stringify(data.d); 
var item = arr[0];

然后你可以用不同的方式来访问每个属性：

empValue = item.empValue; //returns "a" 
empProperty = item["empProperty"]; //returns "SSN"

请添加评论，除了你的downvote – 2013-03-12 13:29:21

我没有downvote，但我认为'var arr = JSON.stringify（data.d）;'将在arr中设置data.d的字符串表示，所以'arr [0 ]'只会返回该字符串的第一个字符。 – Jacopofar 2013-03-12 13:34:36

@Jackopo：请看看演示。它工作正常。 – 2013-03-12 13:50:55

我引述以下链接部分：JSON

为了抵御这，应使用JSON解析器。 JSON解析器将只识别JSON文本，拒绝所有脚本。

var jsonData = JSON.stringify(data.d); 
var myObject = JSON.parse(jsonData);

正如Quentin在上面的评论中提到的那样，为什么我会解析一个对象，它已经是一个JS对象，转换成JSON ... – faizanjehangir 2013-03-12 13:31:35

你对对象进行了stringify，把它放到一个对象的方式是：解析 – 2013-03-12 13:35:40

但是'data .d'是**输入**来stringify，而不是输出！ – Quentin 2013-03-12 13:40:11
