Question

我想解析以下数据，这是来自服务器的对象列表。这是我在数据上使用JSON.stringify(data.d);后的内容：

"[{"__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"}]"

它是一个CellData列表，由empProperty，empValue，isValid，comments作为其属性组成。我无法在JS中访问这些属性。

Answer 1

刚开始使用data.d [i] .empProperty和data.d [i] .empValue，如某些注释中所述，i是数组的索引。不要对它进行字符串化，它已经被解析为一个对象。

了解JSON Here

Answer 2

结构是一个对象数组。因此，您只需通过索引访问每个元素：

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

然后您可以通过不同方式访问每个属性：

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

我引用以下链接中的一节： JSON

为了防止这种情况，应该使用JSON解析器。 JSON解析器只能识别JSON文本，拒绝所有脚本。

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

Javascript：解析JSON对象
