我正在尝试解析已分配给 javascript 变量的 JSON，但由于它具有多个级别，我很难循环遍历它

<script type="text/javascript">

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

        };
        
               

        $(document).ready(function () {


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

            alert(varJson);

        

        });

    </script>

我尝试使用这个：

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

                });

但它只是在我的警报中说对象。

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);
});

你不需要在你的例子中解析它。

使用console.log代替，alert您将在您的网络检查器中使用该对象。

如果你确实想做alert这样的事情

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