limit char entered in form

[pyr]

in my field of form checking I have line for checking email validation:

pattern=/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/;

I'd like that CAPS letters are accepted too  (exmple:  Email@Domain.com), but how to make this?

Very very small change needed. Add the i modifer:

 

pattern="/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/i";
