I've been using php and mysql for a long time, and I always used server side validation, but I never really looked at JS much. Getting back into web design for the first time in a while, I've decided to try JS for client-side validation. I have found a few examples, and have started working on a more advanced contact form. I'm making progress, but I've hit a hitch. the javascript I have so far is - [code] function validate_phone(current, destination) { current.value=current.value.replace(/[^\d]/,''); if (current.getAttribute&&current.value.length == current.getAttribute("maxlength")){ destination.focus(); destination.select(); } } [/code] and the html - [code] <input type="text" id="areaCode" size="2" maxlength="3" onkeyup="validate_phone(this, document.contact.prefix);"> <label>) </label> <input type="text" id="prefix" size="2" maxlength="3" onkeyup="validate_phone(this, document.contact.suffix);"> <label>-</label> <input type="text" id="suffix" size="3" maxlength="4" onkeyup="validate_phone(this, document.contact.body);"> [/code] it works as intended going forward, but the problem I'm having is if you enter a wrong number, editing a full input box becomes tricky. I'm not sure how to handle this. any insight would be great. also, if anyone knows a good resource for regular expressions in javascript I'd love to see it. regex has always been a mystery to me, but I know it will be useful when validating input.
