Generate random password string with requirements in javascript

Question

I want to generate a random string that has to have 5 letters from a-z and 3 numbers.

How can I do this with JavaScript?

I\'ve got the following script, but

Answer 1

I have written a small one inspired from your answer:

(function(){g=function(){c='0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';p='';for(i=0;i<8;i++){p+=c.charAt(Math.floor(Math.random()*62));}return p;};p=g();while(!/[A-Z]/.test(p)||!/[0-9]/.test(p)||!/[a-z]/.test(p)){p=g();}return p;})()

This function returns the password and can be used in bookmarklet like:

javascript:alert(TheCodeOfTheFunction);
