I need help on Array object, (summing number elements)

[oiv]

i.e :

myArray = newArray()
myArray = [2,3,10];
sum = Number(myArray[0]+myArray[1]+myArray[2]);
trace (sum)
//traces 15



Anybody knows how to add number elementes of an array together dynamically?

Instead of typing myArray[0] + myArray[0] etc.

// extend the prototype of the array object:
Array.prototype.sum = function() {
var floatMin = parseFloat(this[0]);
// loop through all elements
for (var i = 1; i<this.length; i++) {
// check if element is a number
if (!isNaN(parseFloat(this[i]))) {
// sum up all numerical elements
floatMin += parseFloat(this[i]);
}
}
return floatMin;
};
// just a check if it works
var a = [12, 3, 5, "a"];
trace(a.sum());

Sorry, I found a mistake in my code... This one is better:

// extend the prototype of the array object:
Array.prototype.sum = function() {
var floatMin = 0;
// loop through all elements
for (var i = 0; i<this.length; i++) {
// check if element is a number
if (!isNaN(parseFloat(this[i]))) {
// sum up all numerical elements
floatMin += parseFloat(this[i]);
}
}
return floatMin;
};
var a = ["foo", 12, 3, 5, "bar", 10, "foobar"];
trace(a.sum());
