将嵌套的json解析为ajax

Question

我的样本json结构为，

{ key : { "data1":data1, "data2":data2 }}

我希望将其解析为＆＃39;数据＆＃39;

$.ajax({
    type: 'post',
    url: 'url',
    data: <--- here ,
    success: function() { 
        *****
    }
});

我该怎么做？

Answer 1

尝试使用JSON.stringify

var data= { "key" : {"data1":"data1", "data2":"data2" }};
new Request.JSON({
    url: '/echo/json/',
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    onSuccess: function(res) {
        document.write(data.key.data1);
        console.log(data.key.data1);
    }
}).send();
