Getting max value(s) in JSON array

Question

I\'m trying to create a JavaScript function which takes information from an array in an external JSON and then takes the max value (or the top 5 values) for one of the JSON

Answer 1

function that's looking for item with the specific property'x maximum:

function getMax(array, propName) {
    var max = 0;
    var maxItem = null;
    for(var i=0; i max) {
            max = item[propName];
            maxItem = item;
        }
    }

    return maxItem;
}

usage:

$(document).ready(function() {
    $('#getMaxBtn').click(function() {
        var max = getMax(jsonArray, 'ppg');

        alert(max.player);
    });
});
