Setting a character limit on a prompt box

Question

What I'm trying to do seems simple to me, so please do excuse me if it is a stupid question, but is there any way to put a character limit on aa javascript prompt box?

Edit, I failed, I meant prompt box. Silly me.

Can you explain your case a little more? Do you mean an alert box or a dialogue (where a user can enter text)? If you are causing the alert box to pop up with text, can you limit your input from that side? — aaron-bond, Jan 27 '14 at 12:03

You might mean a prompt box, but I'll just make this answer relevant to an alert box.

Try:

alert('Text goes here'.substr(0, limit));

Yeah, sorry I meant a prompt. – Doge Jan 27 '14 at 12:09

I'm not sure whether the characters of a prompt box can be limited, but once the typed data is available in JavaScript, you can use substr to limit the characters. – Sharikul Islam Jan 27 '14 at 12:18
