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

to convert Array format like ,

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

Can any one help?

arrays in javascript are not key-value pairs, they are just values. this is not possible. what are you trying to do with this structure that the array of objects can't provide? — jbabey

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

is not valid structure. Array can contain single element. native , or object which contain another items(properties) , or array.

my friend , As a developer we should write valid code . ofcourse we can create a string with invalid data but it wont be interoperable. Dont think as of right now . think how can you make it the right way. im sure the api youre using doesnt enforce you to write this invalid code.

[[1,2],[3,4]] is very different from [[1:2],[3:4]]

What if try this:

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 would then be:

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

as the others said already.. you cannot store key values in javascript arrays. thats what json is for.

Though the syntax is wrong, but if you want you can make this format of string anyway.

But, as you know, you cannot read it back to JavaScript variable.

You can use object oriented capabilities of javascript to accomplish this in more cleaner way.

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 }
