我有以下JS代码：

var response = loadXMLDoc();
var dataset = response.data;
alert(response);
alert (dataset);

“警报（响应）”打印：

{"labels":["-inf - 10","10 - 20","20 - 30","30 - 40","40 - 50","50 - 60","60 - 70","70 - 80","80 - 90","90 - 100","100 - 110","110 - 120","120 - 130","130 - 140","140 - 150","150 - 160","160 - +inf"],"data":[3,8,7,3,7,6,6,7,5,4,10,7,4,4,7,2,0],"count":16}

而“警报（数据集）”给出“未定义”。我试过用 

     var dataset = response["data"];

但它也没有奏效。我想从 JSON 对象中获取数据数组。我怎样才能做到这一点。谢谢

利用var y = JSON.parse(response); alert(y["data"])

尝试这个

var dataset = eval('(' + responce.data + ')');

看到您收到警报以显示响应，它是一个字符串，还不是一个对象。

你需要用它来解析它JSON.parse()

//load your response
var response = loadXMLDoc(),
    dataset;

//parse response
response = JSON.parse(response);

//assign data to dataset
dataset = response.data;

//Hit F12 to see the console
console.log(response);
console.log(dataset);

这 是一个样本
