Introduction to the method of developing a pop-up page using WeChat applet

During the development process of the mini program, we will definitely encounter the situation of developing a pop-up page. Let’s first take a look at the official explanation of the pop-up page of the mini program. The interface of the API is as follows

Judging from the official code example, if you think it is simple, just like an assert, you cannot see the real needs of the pop-up window. . So today HTML51.COM has written a pop-up applet tutorial for your reference.
Let’s take a look at the dynamic renderings of the homepage first:

The first thing we see is the homepage code:

<view class="copyright">
    <view class="copyright_item">CopyRight：All Right Reserved</view>
    <view class="copyright_item">原创作者：51小程序</view>
    <view class="copyright_item">微信小程序开发者社区</view>
    <view class="copyright_item">HTML51.COM</view>
    <view class="copyright_item"><image class="img" src="../copyright/image/logo.png"/></view>
    <view class="goto_counter"><button type="default" bindtap="goto_counter">点击进入弹窗演示页面</button></view>
</view>

Of course, the point is not this. The code of
index.wxml is as follows: The code of

<!--使用animation属性指定需要执行的动画-->  
<view animation="{{animationData}}" class="drawer_box" wx:if="{{showModalStatus}}"> 
   
  <!--drawer content-->  
  <view class="drawer_title">弹窗标题</view> 
  <view class="drawer_content"> 
    <view class="top grid"> 
      <label class="title col-0">标题</label> 
      <input class="input_base input_h30 col-1" name="rName" value="可自行定义内容"></input> 
    </view> 
    <view class="top grid"> 
      <label class="title col-0">标题</label> 
      <input class="input_base input_h30 col-1" name="mobile" value="110"></input> 
    </view> 
    <view class="top grid"> 
      <label class="title col-0">标题</label> 
      <input class="input_base input_h30 col-1" name="phone" value="拒绝伸手党"></input> 
    </view> 
    <view class="top grid"> 
      <label class="title col-0">标题</label> 
      <input class="input_base input_h30 col-1" name="Email" value="仅供学习使用"></input> 
    </view> 
    <view class="top bottom grid"> 
      <label class="title col-0">备注</label> 
      <input class="input_base input_h30 col-1" name="bz"></input> 
    </view> 
  </view> 
  <view class="btn_ok" bindtap="powerDrawer" data-statu="close">确定</view> 
</view>

index.wxss is as follows: The code of

.btn {

  border-radius: 10rpx;  
  text-align: center;

.col-0 {-webkit-box-flex:0;box-flex:0;} 
.col-1 {-webkit-box-flex:1;box-flex:1;} 
.fl { float: left;} 
.fr { float: right;}

index.js is as follows:

Page({ 
  data: { 
    showModalStatus: false 
  }, 
  powerDrawer: function (e) { 
    var currentStatu = e.currentTarget.dataset.statu;  
    this.util(currentStatu) 
  }, 
  util: function(currentStatu){ 
    /* 动画部分 */ 
    // 第1步：创建动画实例   
    var animation = wx.createAnimation({ 
      duration: 200,  //动画时长  
      timingFunction: "linear", //线性  
      delay: 0  //0则不延迟  
    });  
       
    // 第2步：这个动画实例赋给当前的动画实例  
    this.animation = animation;  
   
    // 第3步：执行第一组动画  
    animation.opacity(0).rotateX(-100).step();  
   
    // 第4步：导出动画对象赋给数据对象储存  
    this.setData({ 
      animationData: animation.export() 
    }) 
       
    // 第5步：设置定时器到指定时候后，执行第二组动画  
    setTimeout(function () { 
      // 执行第二组动画  
      animation.opacity(1).rotateX(0).step();  
      // 给数据对象储存的第一组动画，更替为执行完第二组动画的动画对象  
      this.setData({ 
        animationData: animation  
      }) 
         
      //关闭  
      if (currentStatu == "close") { 
        this.setData( 
          { 
            showModalStatus: false 
          } 
        );  
      } 
    }.bind(this), 200) 
     
    // 显示  
    if (currentStatu == "open") { 
      this.setData( 
        { 
          showModalStatus: true 
        } 
      );  
    } 
  } 
   
})
