话不多说,直接上代码:
var countdown = 60;// 倒计时60s定义
var settime = function (that) {
if (countdown == 0) {
that.setData({
alreadyGetVerifyCode: false
})
countdown = 60;
return;
} else {
that.setData({
alreadyGetVerifyCode: true,
coolingTime: `${countdown}s重新获取`
})
countdown--;
}
setTimeout(function () {
settime(that)
}
, 1000)
}
Page({
/**
* 页面的初始数据
*/
data: {
alreadyGetVerifyCode:false,
coolingTime:''
},
/**
* 获取验证码事件
*/
getVerifyCodeAction:function(e) {
if (!this.data.alreadyGetVerifyCode) {
var that = this;
that.setData({
alreadyGetVerifyCode: (!that.data.alreadyGetVerifyCode)
})
settime(that);
} else {
console.log('验证码CD');
}
}
