HTML Form Validation implementing Custom Patterns in Chrome - Regex Not Functioning
I'm working on a project and hit a roadblock. I'm integrating two systems and I'm working on a project and hit a roadblock. I've searched everywhere and can't find a clear answer. I am experiencing problems with my HTML form validation where the custom regex pattern does not seem to work as expected in Chrome. My form includes an input field for a phone number that should only accept numbers in the format of (123) 456-7890. I have specified the pattern like this: ```html <input type="text" id="phone" pattern="\(\d{3}\) \d{3}-\d{4}" required> ``` However, when I try to submit the form with an input like '(123) 456-7890', it correctly validates, but if I enter something like '123-456-7890', it fails to match, even though it seems like it should allow it based on the regex. I have tested this on both Chrome version 94 and Firefox version 92, and it works fine in Firefox but not in Chrome. Additionally, I have tried modifying the regex to include optional groups, like so: ```html <input type="text" id="phone" pattern="(\(\d{3}\) \d{3}-\d{4}|\d{3}-\d{3}-\d{4})" required> ``` But it still fails to validate the second format in Chrome. The behavior message displayed is "Please match the requested format." I have also checked for any JavaScript that might be interfering with the validation. Has anyone else faced this scenario with Chrome? What steps can I take to ensure the regex works properly across browsers? Thanks in advance! This is part of a larger service I'm building. Am I missing something obvious? I've been using Html for about a year now. I'm working with Html in a Docker container on Ubuntu 20.04. Has anyone dealt with something similar?
