Because I Can: Finding the Two Highest Numbers in a Set with JQuery

Another thing I must prove to myself. Ahhhh.....I feel better now!

Enter in 30 numbers, separated by commas:

Here are the highest two numbers in the set: 

window.onload = function(){
	$("#button").click(function () {
		var myStr = $("#textbox").val();
		$("#newTxt").text(findHighest2(myStr));
	});
}

findHighest2 = function (str) {
	var strList = parseString(str, ",");
	var tmpStrList = new String();
	var h1 = 0;  // highest value
	var h2 = 0;  // second highest value
	for (i = 0; i < strList.length; i++) {
		var tmp = parseInt(strList[i]);
		if (tmp > h1) {			
			h2 = h1;
			h1 = tmp;
		} else if (parseInt(strList[i]) > h2) {
			h2 = tmp;
		}
	}
	tmpStrList = h1.toString() + ", " + h2.toString()
	return tmpStrList;
}

parseString = function (str, del) {
	var myStringList = str.split(del);
	return myStringList;
}
