Ajax Response Conversion

I have this array that is returned by ajax: console.log(res); ['07Apr|1', '06Apr|3', '05Apr|12', '04Apr|11', '03Apr|0', '02Apr|0', '01Apr|6', '31Mar|0', '30Mar|7', '29Mar|16', '28M

Solution 1:

You can parse the data you received from the ajax response to create the array.

var populateArray = function (ajaxResponse) {
    var newArray = [];
    ajaxResponse.forEach(function (item, index) {
        var props = item.split('|');
        var obj = {
            date: props[0],
            downloads: props[1]
        };
        newArray.push(obj)
    });

    return newArray;
}

To demonstrate, try

console.log(populateArray(["07Apr|1", "06Apr|3", "05Apr|12", "04Apr|11", "03Apr|0", "02Apr|0", "01Apr|6", "31Mar|0", "30Mar|7", "29Mar|16", "28Mar|5", "27Mar|5", "26Mar|12", "25Mar|9", "24Mar|4", "23Mar|10", "22Mar|16", "21Mar|2", "20Mar|19", "19Mar|22", "18Mar|10", "17Mar|11", "16Mar|10", "15Mar|19", "14Mar|0", "13Mar|4", "12Mar|14", "11Mar|5", "10Mar|26", "09Mar|7", "08Mar|5"]));

Solution 2:

Stringify the entire structure when it is ready, not segments.

Don't use eval ever, use JSON.parse() instead.

        var obj = [];
        var daysBack = 30;
        var objItem = {};
        for(var x = 0; x <= daysBack; x++){
            var currObj = res[x];
            var objCombo = currObj.split("|");
            var objItem = {date: objCombo[0], downloads: objCombo[1]};
            //objItem = JSON.stringify(eval("(" + objItem + ")"));
            obj.push(objItem);
        }
        obj = JSON.stringify(obj);
