Answer 1

You can use lookaheads:

/^(?=.*?[a-z])(?=.*?\d)(?=.*?[...])/i

[...] should hold the special characters you want.

Answer 2

var item = "1a$";
item.match(/^[0-9][a-zA-Z][^a-zA-Z0-9\s\t\n]$/)

That should work

Answer 3

You can use 3 little regex to accomplish that easily (it's more readable) :

• [0-9]
• [a-zA-Z]
• [-_$@...]
