Question

我正在尝试解析我已分配给javascript变量的这个JSON，但由于它有多个级别，我很难通过它循环

<script type="text/javascript">

        var varJson = {
            "d": {
                "results": [
                    {

        };



        $(document).ready(function () {


            //var parsed = JSON.parse(varJson);

            alert(varJson);



        });

    </script>

我试过用这个：

$.each(varJson, function (index, item) {
              alert(item);

                });

但它只是在警报中说对象。

Answer 1

试试这个，

function traverse(jsonObj) {
  if( typeof jsonObj == "object" ) {
    $.each(jsonObj, function(k,v) {
        traverse(v);
    });
  }
  else {
    alert(jsonObj);
  }
}

$(document).ready(function () {
   traverse(varJson);
});

Answer 2

您不需要在示例中解析它。

使用console.log代替alert，您将成为网络检查员中的对象。

如果你想alert做这样的事情

alert(varJson.d.results[0].__metadata.id)

解析具有多个级别的JSON
