<view class=\'header\'>

<view class=\'user\'>
   <input type=\'text\' placeholder=\'用户名\'></input>
</view>

<view class=\'password\'>
   <input type=\'password\' placeholder=\'密码\'></input>

    <button  class=\'register\' bindtap=\'register\'>注       册</button>

　　下面是wxss的修饰代码

.header{
  text-align: center;
  width: 100px;
  height: 100px;
   margin: 50px auto;
}
.header image{
  width: 100%;
  height: 100%;
 
}
.user{
  width: 100%;
  height:50px;
 margin-bottom:20px
}
 input{
  width: 100%;
  border-bottom: 1px solid wheat;
  height: 40px;
 
}
.register{
  background: green;
  width: 80%;
  height: 40px;
  margin-top: 20px;
  color: white;
  text-align: center;

}

　　这个是js的代码

const app = getApp()
Page({
  data:{ 
    
  },

register:function(){

  wx.showLoading({
    title: \'注册中...\',
    
  }),
    setTimeout(function () {
      wx.hideLoading()
    }, 2000)

}
 
})
