modifying js function help

[darkfreaks]

i need help slightly modifying a function how would i make it so instead of it adding points if i add in symbols like !@#$%^&*()-=+ it subtracts instead of adds points.

 

and if it detects a dash or underscore it adds points

here is the function:

function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != "function") {
	window.onload = func;
}
else {
	window.onload = function() {
		if (oldonload) {
			oldonload();
		}
		func();
	};
}
}

String.prototype.strReverse = function() {
var newstring = "";
for (var s=0; s < this.length; s++) {
	newstring = this.charAt(s) + newstring;
}
return newstring;
//strOrig = ' texttotrim ';
//strReversed = strOrig.revstring();
};
