jQuery实现倒计时按钮功能代码分享
代码一:
{ wait:90, hsTime:function(that){ if (this.wait == 0) { $('#hsbtn').removeAttr("disabled").val('重发短信验证码'); this.wait = 90; } else { var _this = this; $(that).attr("disabled", true).val('在'+_this.wait+'秒后点此重发'); _this.wait--; setTimeout(function() { _this.hsTime(that); }, 1000) } }, }

代码五:
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>
