微信小程序实现左滑删除

一、效果

二、代码

  实现思路使用的是官方提供的movable-area 嵌套movable-view

1、movable-area:注意点,需要设置其高度,否则会出现列表内容重叠的现象。

2、由于movable-view需要向右移动,左滑的时候给删除控件展示的空间,故 movable-area 需要左移 left: -120rpx;

3、movable-view右移left: 120rpx;。 通过 width: calc(100% - 120rpx);左划的距离。

4、 需要给movable-view组件设置层级 z-index: 1001;越高越好至少比删除组件层级高,避免被遮住。

 5、 <view class="itemDelet">删除</view> 的位于movable-view组件右下,左滑movable-view显示处删除组件。

.moveArea {
  display: flex;
  flex-direction: row;
  width: calc(100% + 120rpx);
  justify-content: center;
  left: -120rpx;
  height: 188rpx;
}
 

movable-view

.movableView {
  display: flex;
  flex-direction: row;
  width: calc(100% - 120rpx);
  z-index: 1001;
  left: 120rpx;
}

源代码如下:


Page({

  /**
   * 页面的初始数据
   */
  data: {
    pushedData:[{messageTitle:'饼干',messageContent:'饼干爱吃'}],//已推送数据
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad() {
    
  },

  /**
   * 生命周期函数--监听页面初次渲染完成
   */
  onReady() {

  },

  /**
   * 生命周期函数--监听页面显示
   */
  onShow() {

  },

  /**
   * 生命周期函数--监听页面隐藏
   */
  onHide() {

  },

  
  /**
   * 生命周期函数--监听页面卸载
   */
  onUnload() {

  },

  /**
   * 页面相关事件处理函数--监听用户下拉动作
   */
  onPullDownRefresh() {

  },

  /**
   * 页面上拉触底事件的处理函数
   */
  onReachBottom() {

  },

  /**
   * 用户点击右上角分享
   */
  onShareAppMessage() {

  },
  
  // 退出页面
  logout:function(){
    wx.navigateBack({})
  },

})
