Parse Json data in Jquery

Question

I am new to Jquery, Ajax and JSON. I am facing issue with the parsing of Json data. I have been through many questions on stackoverflow

Parsing JSON objects for HTML

Answer 1

When you specify the dataType as JSON, jQuery will automatically parse it for you. Parsing it again as you are (multiple times, even) will cause issues. Try this:

success: function(result) {
    console.log(result.od);
    console.log(result.od[0].percentageCompleted);
}

I'm not entirely sure what your $.each loop is trying to do as there is no tagName property in your object.

Answer 2

no need of parsing it because you have already mentioned it as json you can simply do like this:

                 success: function(result) {
    console.log(result.od);
    console.log(result.od[0].percentageCompleted);
console.log(od);
    $.each(result, function(idx, obj) {
     console.log(obj[0].dateProcessed);
    });         
}

Answer 3

Try this code.

$.ajax({
    /* type : "POST", */
    url: "launchapptest",
    /* contentType: "application/json; charset=utf-8", */
    data: "processDateInput=" + processDate,
    dataType: "json",
    async: true,
    success: function (result) {
        var od = JSON.stringify(result);
        var obj = JSON.parse(od);

        $.each(obj, function (index, value) {
            console.log(obj[index][0].percentageCompleted);
            console.log(obj[index][0].processRunning);
            console.log(obj[index][0].remainingTime);
            console.log(obj[index][0].successBatchCount);
            console.log(obj[index][0].totalBatchCount);
            console.log(obj.processDateInput);
            $.each(obj[index][0].dateProcessed, function (ind, val) {
                console.log(val);
            })
        });

    }
});

What is the is the return data of your AJAX call

is like this then

{
    "od": [
        {
            "dateProcessed": [
                "09/11/2014",
                "09/12/2014"
            ],
            "percentageCompleted": 25,
            "processRunning": 0,
            "successBatchCount": 0,
            "totalBatchCount": 0
        }
    ],
    "processDateInput": "12/11/2014"
}

you can parse it like this

var json = JSON.parse(result);
            var od = json['od'];
            var processDateInput = json['processDateInput'];

            $.each(od, function(index, value){
                console.log(value, index);
            });

hope it would work on you.
