Verify password contains letter

$('#password').val().indexOf(/[a-z]/) != -1)

Does this work? if so is there something wrong with it because its not working.

No this will not work because you have to use match() function for that.

I also recommend that if you want only numbers then you should try to validate only numbers.

Do not allow anything else except number.

if( $('#password').val().match(/[0-9]+/) ){
    // Contains only numbers from 0-9
}

Do your check like the following because you want to work with an object supporting regular expression syntax:

var valContainsLetter = /[a-z]/i.test($('#password').val())

The i flag is to support lower and upper case letters by the way.

The indexOf method accepts a string, not a regular expression.

If you want to test a regular expression then use match
