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
