使用javascript或jQuery进行JSON解析

Question

I have the following valid JSON

[
    {
        "series": [
            {
                "name": "Comp",
                "data": [
                    753,
                    384,
                    864,
                    654
                ],
                "color": "#FFAC3F"
            },
            {
                "name": "Ind",
                "data": [
                    642,
                    456,
                    983,
                    564
                ]
            },
            {
                "name": "Store",
                "data": [
                    832,
                    243,
                    646,
                    777
                ],
                "color": "#FF0000"
            }
        ]
    }
]

I want to return all the data inside "series" but doing something like say assigning this to a variable and then using data.series is not returning anything. How would I do this using jquery or javascript? This data is actually getting returned in a jquery JSON ajax request like so....

$.getJSON(url,  function(data) {

Answer 1

Your JSON is wrapped in an array. You want

data[0].series

---

For a better visual, review this

var data = [{foo: "bar"}, {hello: "world"}];

To get foo , you would use

data[0].foo; // "bar"

To get hello , you would use

data[1].hello; // "world"

---

Considering you have

var data = [{series: [...]}];

You need to use

data[0].series; // [...]

Answer 2

$.getJSON(url, function(data) {
    console.log(data[0].series)
});
