Question

我正在使用highchart插件开发图表。为图表提供动态输入。所以，我需要将JSON格式更改为Array。如何使用javascript将JSON数组对象格式更改为Array？

[
        {
            "scoreCount": "108",
            "legendDesc": "Excellent ",
            "colorPatchCode": "#009900"
        },
        {
            "scoreCount": "20",
            "legendDesc": "Fail ",
            "colorPatchCode": "#FF0000"
        }
    ]

转换数组格式，如

[
        [
            "scoreCount": "108",
            "legendDesc": "Excellent ",
            "colorPatchCode": "#009900"
        ],
        [
            "scoreCount": "20",
            "legendDesc": "Fail ",
            "colorPatchCode": "#FF0000"
        ]
    ]

任何人都可以帮忙吗？

Answer 1

[
            "scoreCount": "108",
            "legendDesc": "Excellent ",
            "colorPatchCode": "#009900"
        ],

是无效的结构。数组可以包含单个元素。本机或包含其他项（属性）或数组的对象。

如果尝试这样做：

var arr = [
        {
            "scoreCount": "108",
            "legendDesc": "Excellent ",
            "colorPatchCode": "#009900"
        },
        {
            "scoreCount": "62",
            "legendDesc": "Good ",
            "colorPatchCode": "#99CC00"
        },
        {
            "scoreCount": "55",
            "legendDesc": "Acceptable ",
            "colorPatchCode": "#FFFF00"
        },
        {
            "scoreCount": "31",
            "legendDesc": "Poor ",
            "colorPatchCode": "#FF9900"
        },
        {
            "scoreCount": "20",
            "legendDesc": "Fail ",
            "colorPatchCode": "#FF0000"
        }
    ];

for (i = 0;i<arr.length;i++) {
    var a = [];
    for (n in arr[i]) {
        a[n] = arr[i][n];
    }
    arr[i] = a;
}

for (i = 0;i<arr.length;i++) {
    alert(arr[i]['scoreCount']);
}

http://jsfiddle.net/sPN7z/

var source = [
    {
        "scoreCount": "108",
        "legendDesc": "Excellent ",
        "colorPatchCode": "#009900"
    },
    {
        "scoreCount": "62",
        "legendDesc": "Good ",
        "colorPatchCode": "#99CC00"
    },
    {
        "scoreCount": "55",
        "legendDesc": "Acceptable ",
        "colorPatchCode": "#FFFF00"
    },
    {
        "scoreCount": "31",
        "legendDesc": "Poor ",
        "colorPatchCode": "#FF9900"
    },
    {
        "scoreCount": "20",
        "legendDesc": "Fail ",
        "colorPatchCode": "#FF0000"
    }
];

var out = [];

for (var i = 0; i < source.length; i++) {
    var tmp = [];
    for (var i2 in source[i]) {
        tmp.push(source[i][i2]);
    }
    out.push(tmp);
}

out将是：

[
    ["108","Excellent ","#009900"],
    ["62","Good ","#99CC00"],
    ["55","Acceptable ","#FFFF00"],
    ["31","Poor ","#FF9900"],
    ["20","Fail ","#FF0000"]
]

正如其他人已经说过的那样..你不能在javascript数组中存储键值。这就是json的用途。

虽然语法错误，但是如果你想要的话，你仍然可以制作这种格式的字符串。

但是，正如您所知，您无法将其读回JavaScript变量。

Answer 5

您可以使用javascript的面向对象功能以更清晰的方式实现此目的。

var jsonArray = [ { "scoreCount": "108", "legendDesc": "Excellent ", "colorPatchCode": "#009900" }, { "scoreCount": "62", "legendDesc": "Good ", "colorPatchCode": "#99CC00" }, { "scoreCount": "55", "legendDesc": "Acceptable ", "colorPatchCode": "#FFFF00" }, { "scoreCount": "31", "legendDesc": "Poor ", "colorPatchCode": "#FF9900" }, { "scoreCount": "20", "legendDesc": "Fail ", "colorPatchCode": "#FF0000" } ];
function MyJsObject(scoreCount, legendDesc, colorPatchCode) { this.scoreCount = scoreCount; this.legendDesc = legendDesc; this.colorPatchCode = colorPatchCode; } function createJSArray() { var jsArray = new Array(); for(i = 0; i < jsonArray.length; i++) { var m = new MyJsObject(jsonArray[i].scoreCount, jsonArray[i].legendDesc, jsonArray[i].colorPatchCode); jsArray[i] = m; } alert(jsArray[4].scoreCount);//access any object like this }

从JSON Array对象转换为Array for highchart？
