Parameters

array The array to be sorted. (See below for an implementation on the Array Native itself, which makes this variable unnecessary).

key The key to sort by. Make sure every object in your array has this key.

Examples

var objs = [
	{fruit:"cherry"},
	{fruit:"apple"},
	{fruit:"banana"}
];

console.log(objs.sortObjects('fruit'));
// Logs [{fruit:"apple"},{fruit:"banana"},{fruit:"cherry"}] to the console

The code

sortObjects: function(array, key) {
	for (var i = 0; i < array.length; i++) {
		var currVal = array[i][key];
		var currElem = array[i];
		var j = i - 1;
		while ((j >= 0) && (array[j][key] > currVal)) {
			array[j + 1] = array[j];
			j--;
		}
		array[j + 1] = currElem;
	}
}

Implemented on the Array native:

Array.implement({
	sortObjects: function(key) {
		for (var i = 0; i < this.length; i++) {
			var currVal = this[i][key];
			var currElem = this[i];
			var j = i - 1;
			while ((j >= 0) && (this[j][key] > currVal)) {
				this[j + 1] = this[j];
				j--;
			}
			this[j + 1] = currElem;
		}
	}
});
