<div class="input-item"> <span class="des">验证码</span> <input class="input" placeholder="填写验证码" id="validateCode" /> <a href="javascript:void(0)" v-on:click="GetverificationCode">{
{
count}}</a> </div> js
data: {
count: "获取验证码", timer: null，//关键 }, methods:{
//获取验证码 GetverificationCode: function (e) {
let that = this; $.ajax({
url: "/OrderMeal/SendVerificateCode", data: {
phone: $("#phone").val() }, success: function (data) {
if (data.isSuccess == false) {
$.toptip('系统繁忙，请稍后再试', 'warning'); return; } const TIME_COUNT = 60;//设置60秒 if (!that.timer) {
that.count = TIME_COUNT; that.show = false; that.timer = setInterval(() => {
if (that.count > 0 && that.count <= TIME_COUNT) {
that.count--; } else {
clearInterval(that.timer); that.timer = null; that.count = "重新获取"; } }, 1000) } } }) }, }, 二、在循环中创建多个定时器，比如美团未支付页面有多个订单，都是从下单时间开始倒计时15分钟
for (var i = 0; i < that.orderList.length; i++) {
let j = i;//重点 (function (j) {
//重点，跟循环打印一个道理，否则得到的的是最后一个，而不是每一个值都有 that.orderList[j].timer = null;//重点 var startTime = new Date().getTime(); var endTime = Date.parse(that.orderList[j].orderTime);//下单时间换算成毫秒 endTime += //加30分钟（倒计时三十分钟） var leftTime = endTime - startTime;//下单后的30分钟-现在的时间 if (!that.orderList[j].timer) {
that.orderList[j].timer = setInterval(() => {
if (leftTime > 0) {
leftTime = leftTime - 1000 var m = Math.floor(leftTime / 1000 / 60 % 60); var s = Math.floor(leftTime / 1000 % 60); that.$set(that.orderList[j], "Min", m)//上一篇有讲，给数组对象加新属性 that.$set(that.orderList[j], "Sec", s) //console.log(that.orderList[j].Min, s) } else {
clearInterval(that.orderList[j].timer); that.orderList[j].timer = null; } }, 1000) } })(j) } 版权声明：本文内容由互联网用户自发贡献，该文观点仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请联系我们举报，一经查实，本站将立刻删除。
