最近在寫短信發送驗證碼，就寫了個js/jquery倒計時發送驗證碼按鈕<script language="javascript" src="jquery-1.7.1.min.js"></script><input type="button" id="btn" value="免費獲取驗證碼" /><script type="text/javascript">var wait=10;function time(t) { if (wait == t) { t.removeAttribute("disabled"); t.value="免費獲取驗證碼"; wait = 10; } else { t.setAttribute("disabled", true); t.value="重新發送(" + wait + ")"; wait--; setTimeout(function() { time(t) }, 1000) } } $(document).ready(function(){ $("#btn").click( function () { time(this); });});</script>新聞熱點
