Checking for uppercase/lowercase/numbers with Jquery
- by user1725794
Either I'm being really retarded here or its just the lack of sleep but why doesn't this work? If I use the "or" operator it works for each separate test but as soon as it change it to the "and" operator it stops working.
I'm trying to test the password input of a form to see if its contains lowercase, uppercase and at least 1 number of symbol. I'm having a lot of trouble with this so help would be lovely, here is the code I have.
var upperCase= new RegExp('[^A-Z]');
var lowerCase= new RegExp('[^a-z]');
var numbers = new RegExp('[^0-9]');
if(!$(this).val().match(upperCase) && !$(this).val().match(lowerCase) && !$(this).val().match(numbers))
{
$("#passwordErrorMsg").html("Your password must be between 6 and 20 characters. It must contain a mixture of upper and lower case letters, and at least one number or symbol.");
}
else
{
$("#passwordErrorMsg").html("OK")
}
