foreach() in Javascript?

[Sandman]

How do I create an array in JavaScript and then go through it?

I want to feed a function with the string "foo,bar,rab,oo f" and want JavaScript
to do something with each line, like this (in pseudo-code):

myfunc("foo,bar ,rab,oof");

function myfunc(string){
foreach i (split(",", string)){
alert(i);
}
}

Or something like that.

var a = [1, 2, 3, 4, 5];
for (var i = 0; i < a.length; i++)
alert(a[i])

I don't see any lines there, it is a string literal.

function myfunc(string){
var a = string.split(', ');
for (var i = 0; i < a.length; i++) {
alert(a[i]);
}
}

myfunc("foo,bar ,rab,oof");

I believe the construct you may be looking for is, or at least one that
should get you started, is: "for ... in"

Docs and an example can be found at:

Very close:

function myfunc(string) {
var arr = string.split(", ");
for (var i in arr) {
alert(arr[i]);
}
}
