 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", 
  }) 
  }
