</view>
<button class="lgbut" formType="submit">下一步</button>
</form>
data: {
sendmsg: "sendmsg",
getmsg:"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)}
},

登录后复制
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
