Javascript JSON Parse JSON和Jquery ParseJson在visualforce中不起作用

我试图在salesforce visual force中解析json字符串，它在标准HTML jquery测试页面中运行良好，但在我的visual force页面中不起作用。我检查了，json字符串是有效的。有人能帮忙吗

MyController.MyCompany( j$('#input').val(),function(result,event){

              alert(result);// this alert shows the JSON string from controller
              var parsedRes=jQuery.parseJSON(result);
              var parsedRes2=JSON.parse(result);
              alert(parsedRes); //this is not alerting
              alert(parsedRes2); this is not alerting

我在其他JSON验证网站上也做了同样的尝试，除了VisualForce之外，一切都很好

JSON是：

数据已经是json格式。您不需要再次解析它

您可以控制台.log（'parsedRes'，parsedRes'）吗？控制台中没有任何内容。由于某种原因，json字符串似乎未被解析。请使用getJson方法而不是MyController.MyCompany
