let list = { QuestionDetailData: "[{QuestionDetailId:146,'QuestionDetailName':'有'},{'QuestionDetailId':147,'QuestionDetailName':'没有'}]" }
eval(),这个函数就可以了吧
var str="[{name:'zhangsan',age:10},{one:1,two:2}]";
var arr=eval(str);
console.log(arr);
好了
解析json字符串即可
var value = "[111,22,333,44,555,66]";
var array = JSON.parse(value);
var obj = JSON.parse(text);
var detailData = list.QuestionDetailData;
var jsarr=JSON.parse(detailData);
