Topic: Regular Expressions for jQuery Form Validation?

christopherbirwin pro asked 4 years ago


Expected behavior

When a user enters an incorrect format for an email address and tries to submit the form, an error displays, which indicates the information entered is invalid and prevents the form doesn't submit (i.e., it allows the use of regular expresssions).

Actual behavior

When a user enters an incorrect format for an email address and tries to submit the form, an error doesn't display displays, which indicates the information entered is invalid, and the form is not prevented from submitting (i.e., there doesn't appear to be a way to use regular expressions).

Just FYI,

You could use the pattern attribute, which takes regex

<input type="text" name="ssn"
       pattern="^\d{3}-\d{2}-\d{4}$"
       title="The Social Security Number" />

Never mind! I didn't realized it's built into HTML5:

HTML 5 Validation

I found the regex I needed here:
