select elements from json object

Question

I am working with jquery and ajax.I want to select json object having same element. ie, here is my json object.

 {"data":[{"row":15,"name":"aaa"},
          {"row":15,"name":"bbb"},
          {"row":10,"name":"ffff"},
          {"row":15,"name":"rrr"}
 ]}

Then, I want to select all 'name' having same 'row'. How shall I do it using jquery?

Could you clarify this? What do you mean by selecting all that have the same row? How do you decide which row to get? Will there only ever be 2 different rows? — feildmaster

Array.filter() if you want a pure js solution...

success: function(result) {
    var test = 15;
    var subset = result.data.filter(function(o) { return o.row === test; });
}

You can use grep for that.

var obj = {
    "data": [{
        "row": 15,
        "name": "aaa"
    }, {
        "row": 15,
        "name": "bbb"
    }, {
        "row": 10,
        "name": "ffff"
    }, {
        "row": 15,
        "name": "rrr"
    }]
};

function filterData(rowNumber) {
    var filteredrObject = jQuery.grep(obj.data, function(element, i) {
        return element.row == rowNumber;
    });
    return filteredrObject
}
console.log(filterData(15));

Fiddle
