    Assuming this is a client-side (i.e. web browser) script, using something like onChange() or onBlur(), it should be easy enough to validate on the given event and detect the boolean outcome. However if you're using onChange() the validation will run as soon as you start typing, whereas if you were to use onBlur() the validation would only run after focus moves away from that input field. If you really want to use onChange() then you will need to code extra checks to periodically poll the contents (based on key-up detection perhaps) in order to allow time to type the full value. I'm not familiar with the syntax you have used so if you're coding within a framework rather than rolling your own then I can't comment any further. It's pretty standard stuff and usually with bugs like that it's something very simple and [eventually] obvious! Good luck.

    Obviously, you should not stop at just HTML5-based validation, enter almost any kind of string into an input element and submit a form.

    3. You can validate regular expression on server side so only when you hit submit button RegularExpressionValidator will do validation at server and not at client side. To do that you need to set property of validator. EnableClientScript="False". Share. answered Nov 29 '11 at 9:03. pramodtech. pramodtech. 5,900 15.

    This validation is inline which means K2 runs the comparison between the text box entry and the regular expression as soon as the cursor goes to another control. In a later step, you apply a validation at the rule level where K2 makes the comparison once again after an event of some kind, typically submitting the form.

Outsystems provide built in validation on client and server side for multiple types like number, email, date and others.

    Once you learn the art of using regular expressions you can use it with many computer languages. Regular Expressions. The following is how regular expressions can be used [abc] – find any character in the brackets a, b or c [a-z] – find the range of characters within brackets i.e. a to z lowercase. Can also be used with numbers [0-9]
