js怎么遍历json数组对象， 如何遍历出content里面的数值，格式如下var content= infoList: [

{ type: 1, typeList: [{ ID: 101, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 }] },

{ type: 2, typeList: [{ ID: 102, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 },
{ ID: 15, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 },
{ ID: 18, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 }] },

{ type: 3, typeList: [{ ID: 11, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 },
{ ID: 13, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 }] },

{ type: 4, typeList: [{ ID: 10, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 },
{ ID: 9, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 }] },

{ type: 5, typeList: [{ ID: 16, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 },
{ ID: 23, startDate: '2016-09-08', endDate: '2016-09-08', adultNum: 0, childrenNum: 0 }] }]

}

var typeArr = new Array();
for(var i = 0;i<infoList.length;i++)
{
    typeArr.push(infoList[i].type)   //获取到type的值
    for(var j = 0;j<infoList[i].typeList.length;j++)
    {
        var info = infoList[i].typeList[j];
        alert(info.ID);
        alert(info.startDate);
        alert(info.endDate);
        alert(info.adultNum);
        alert(info.childrenNUm);
    }
}

这样就遍历出了所有的数据了
