User control not validating

If you want to restrict the input of a text field to numbers without having the up/down arrows associated with the input box, you can always just set the input type to of "\d " (one or more numbers). So something along the line of [email protected] would be perfectly valid! Anyone out there know how to adjust the url validation so that it will accept inputs in the following format: no need to force a user to input or https:// You can find a comparison of some interesting regexes for validating URLs here.

We have a separate article with details on validating passwords using HTML5, including Java Script code for customising the browser generated alert messages. You just need to pick one and then remove the portion that detects the protocol (xxx://).

Again, not very helpful, but it will stop people trying to input their email address or other such nonsense. Careful examination of the RFCs associated with email addresses has been conducted repeatedly and has been proven to require the use of recursion in order properly determine the validity of an email address using the full set of RFC specifications.

As mentioned above, we can improve on this by making use of the are already implicit so the input has to match the entire expression. If anyone wants to contribute a more thorough expression to test for valid email or url format, feel free to post it using the Feedback option above.. Since it is not possible to recurse when using a regular expression it is also not possible to create a truly accurate regex for doing email address validation.

Also each browser has a slightly different default behaviour.

The simplest change you can make to your forms is to mark a text input field as 'required': This informs the (HTML5-aware) web browser that the field is to be considered mandatory.

By selecting this check box, you make the field associated with that control a required field.

When you design a browser-compatible form template, some controls are unavailable in the Controls task pane because they cannot be displayed in a Web browser.

Some data validation features work differently in a Web browser than they do in Info Path.

Other HTML5 input types include: -related options do have an effect at least in Opera, with pop-up calendars and other devices appearing to assist with input. But as you see, lots of strange looking URLs are actually valid.

While it would be great to see something like this in every browser, for now you probably need to stick with the ubiquitous Java Script plugins. Arjen, You're correct: and it's not just the plus sign ( ), although I have to admit, I've never seen that used in an email address before.

While the code we're using is slightly more complicated, this should get you started: Some of the articles below, particularly the first two, provide other style/scripting options and solutions for supporting older browsers. Wikipedia has a list of potentially valid email formats here: en.wikipedia.org/wiki/Email_address#Valid_email_addresses Most browsers accept [email protected] as valid for email input as it can be technically correct in some situations - on an intranet for example. How do you only show the fields as 'invalid' after the user leaves (blurs? It's ugly to have ready icons displayed when the page loads.
