Answer 1

put @visph 's function in js page and also add:

var t,v;
window.onload = function(){alert(countv2(prompt("insert string"),prompt("insert character")));};

Answer 2

function countv2(t,v) {
var r=new RegExp(v,"g");
return t.match(r).length;
}

But it's repetition :D

Answer 3

Not sure if he wants the ignore-case flag...

Answer 4

Your're right: I'll edit ^^

Answer 5

@ValentinHacker:

I see just now, but on one hand your "var t,v;" is unnecessary ( these are 2 globals variables, but in my function "t" and "v" are parameters variables ), and on the other hand it's in my code where it's more valid to add a var statement for the "r" variable ;)
