如何在javascript上以JSON显示某人数据？

Question

        var example = {
        "Equation" : [{
        "name" : "My Equation",
        "xMin" : [41901.0840,4,3,5,2],
        "yMin" : [0.0000,4,5,7,8,9,3,1]
        }
    ]
};

        var e = JSON.parse(example);

        alert(e.example.xMin);

/* What's the problem, can't show any data on array object, at least xMin is Array, how can show someone number on array. Thanks!. */

Answer 1

There is no need to parse since it's already a valid object. To get the property you need to get the Equation property and then it's the first element afterward get xmin property.

 var example = { "Equation": [{ "name": "My Equation", "xMin": [41901.0840, 4, 3, 5, 2], "yMin": [0.0000, 4, 5, 7, 8, 9, 3, 1] }] }; alert(example.Equation[0].xMin);
