formfield requires 2 commas

[Crescionini Sascha]

hello ng

does anyone have an idea how to check in an input field,
if the value contains exactly two commas?

examples:
"gaga,gogo,gugu" or ",,gagaggigi"

any ideas?

s = "gaga,gogo,gugu";
n= s.replace(/[^,]+/g,"").length;
alert(n);

[the + speeds things up, says John S.]

O sorry, you wanted a test:

s = "gaga,gogo,gugu";
if(s.replace(/[^,]+/g,"").length==2)alert("Yes");
