今天看了一段代码,是关于邮箱的验证的,怕自己忘记了,就写了一下,和大家分享一下
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script> window.onload = function() { } function dianjishijian() { var x = document.getElementById("youxiang").value; var atpos = x.indexOf("@"); var dotpos = x.lastIndexOf("."); if (atpos < 1 || dotpos < atpos + 2 || dotpos + 2 >= x.length) { alert("请输入正确的邮箱地址"); return false; } } </script> </head> <body> <input type="text" name="youxiang" id="youxiang" value="" /> <button id="" onclick="dianjishijian()">点击试试</button> </body> </html>
