今天碰到要实现一个类似那种短信验证码60秒倒计时的需求,好久不写js,有点手生.把代码记录下,方便后续查阅. 这里我用了jQuey,毕竟写起来简洁点.下面直接看效果和代码. 一.效果                                                                            二.代码 (1)html <input type="button" id="btn" value="免费获取验证码&qu

<html> <head> <meta charset="utf-8"/> <script type="text/javascript"> ; var sh; function counter(){ sh = setInterval(jishi,); } function jishi(){ var btn = document.getElementById("btn"); btn.innerHTML

需求来自于csdn问答,可以利用这个原理做秒杀抢单外挂. 代码示例如下: <html> <head> <meta charset="utf-8"/> <script type="text/javascript"> var count = 10; var sh; function counter(){ sh = setInterval(jishi,1000); } function jishi(){ var btn =

按天倒计时 HTML代码1: <Script Language="JavaScript"> <!-- Begin var timedate= new Date("January 14,2006"); var times="研究生考试"; var now = new Date(); var date = timedate.getTime() - now.getTime(); var time = Math.floor(date /

__block ; __block UIButton *verifybutton = _GetverificationBtn; verifybutton.enabled = NO; dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, ); dispatch_source_t _timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_T

__block NSInteger timeout= ; //倒计时时间 KWeakSelf dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, ); dispatch_source_t _timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, , ,queue); dispatch_source_set_timer(_

用html代码的话就这样: <meta http-equiv="Refresh" content="10;URL=http://www.baidu.com"> 把它加到head标签下但是不能实现倒计时效果,如果要实现倒计时的话就要用flash,或者javascript,我把带js的html代码发给你自己粘贴到记事本试试吧 <html> <head> <title>10秒后跳转</title> </he

其实要实现这个功能原理非常简单,就是setInterval+setTimeout+clearInterval结合使用,首先在data里定义一个变量second,初始值为60,然后在setInterval里执行每秒减1的操作,setTimeout在60秒后执行clearInterval清除定时器的操作 <view v-if="showText==true" class="send" @click="getCode">发送验证码</

wait:"60", content:"验证码", canClick: true, daojishi(){ if(!this.canClick) return this.canClick = false this.content = this.wait + '秒' //这里解决60秒不见了的问题 let clock = window.setInterval(() => { this.wait-- this.content = this.wait + '秒' i
