Question

I have a JavaScript object in the format

{
    "header": {
        "dataFields": ["number", "name", "quantity", "id", "from"]
    },
    "data": [
        "20|sam|12|2|2012-06-29T00:00Z|",
        "18|peter|231|12|",
    ]
}

I am trying to get it in to this format:

[{"number" : "20", "name":"sam", "quantity" : "12", "id":"2"},
 {"number" : "18", "name":"peter", "quantity": "231", "id" 12"}]

I dont want the field “from in the output array.. what could be the best way to acheive it??

var l={};

for ( var key in responseData.positions[i]){
    l.name=key;
        for(var k=0; k<responseData.positions.length;k++){
            for ( var key in responseData.positions[k]) {
                l.value= responseData.positions[k][key] ;
            }
        }
mainArray.push(l);

You can use the array map method to iterate through the data array and convert it.

Code and live demo: http://jsfiddle.net/N9QyQ/

var object={
"header": {
    "dataFields": ["number", "name", "quantity", "id", "rom"]
},
"data": [
    "20|sam|12|2|2012-06-29T00:00Z",
    "18|peter|231|12|"
 ]
} ;
var result=object.data.map(function(string){
    var split=string.split("|"), item={};
    for (var i=0;i<4;i++) {
        item[object.header.dataFields[i]]=split[i];
    }
    return item;
});
