A JavaScript for verifying <a href="http://www.nfljerseys-supply.com/ "><strong>football jerseys</strong></a> email address in a form By Zhanshan Dong on August 25th, 2011 To get a valid email address in a web form, you have to make sure that users enter a valid email address. One way to that is using a javascript to do it. After users enter an email address, use javascript to verify it right way. If the email is valid, move to the next field. Otherwise, popup an alert dialog and highlight the email input box. Allow users to modify their inputs. Here is a simply JavaScript <a href="http://www.nfljerseys-supply.com/"><strong>kids nfl jerseys</strong></a> code. function verifyEmail(formname, email) { var emailRegEx = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}/i; if (email.search(emailRegEx) == -1) { alert("请输入一个有效的电å*�邮件地å�€. "); var myform = window.document.forms[formname]; myform.elements["email"].focus(); } } <a href="http://www.nfljerseys-supply.com/"><strong>NFL jerseys supply</strong></a>
