微信小程序之发送短信倒计时功能

点击后

代码

<form bindsubmit="formSubmit" bindreset="formReset"> 
<view class="fidpas"> 
 <input type="number" class="fidpas_inp"placeholder-class="lgin_place" placeholder="请输入手机号" name="phonenumber" /> 
 <input type="number" class="fidpas_inp2"placeholder-class="lgin_place" placeholder="请输入短信验证码" name="msg" /> 
 <button class="{{sendmsg}}" bindtap="sendmessg">{{getmsg}}</button> 
</view> 
<button class="lgbut" formType="submit">下一步</button> 
</form> 
data: { 
 sendmsg: "sendmsg", 
 getmsg:"获取短信验证码", 
 }, 
 /** 
 * 获取短信验证码 
 */ 
 sendmessg:function(e){ 
 if (timer==1){ 
 timer=0 
 var that=this 
 var time=60 
 that.setData({ 
 sendmsg:"sendmsgafter", 
 }) 
 var inter=setInterval(function(){ 
 that.setData({ 
 getmsg: time + "s后重新发送", 
 }) 
 time-- 
 if(time<0){ 
 timer=1 
 clearInterval(inter) 
 that.setData({ 
 sendmsg: "sendmsg", 
 getmsg: "获取短信验证码", 
 }) 
 } 
 },1000)} 
 }, 

思路：将BUTTON后样式和内容设为变量，点击之后setData将其改变即可
