最近在写短信发送验证码，就写了个js/jquery倒计时发送验证码按钮<script language="javascript" src="jquery-1.7.1.min.js"></script><input type="button" id="btn" value="免费获取验证码" /><script type="text/javascript">var wait=10;function time(t) { if (wait == t) { t.removeAttribute("disabled"); t.value="免费获取验证码"; wait = 10; } else { t.setAttribute("disabled", true); t.value="重新发送(" + wait + ")"; wait--; setTimeout(function() { time(t) }, 1000) } } $(document).ready(function(){ $("#btn").click( function () { time(this); });});</script> |
