使用字符串变量检索JSON对象的值

Question

我有一个json数据

var data={"mainVariants": [
        {
            "header": "Measure"
        },
        {
            "header": "Disposal"
        },
         {
            "header": "Stairs"
        },
         {
            "header": "Furniture"
        }
    ],
    "Measure": {}}

var val1=data.mainVariants[0].header;//returned as "Measure"

现在我想检索data.val1.Pls帮助

Answer 1

试试这个     var val1 = data.mainVariants [0] .getString（“header”）;

Answer 2

您可以var obj = data[val1]
