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：注意点，需要设置其高度，否则会出现列表内容重叠的现象。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;，movable-view右移left: 120rpx;。 通过 width: calc(100% - 120rpx);左划的距离。

.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;
}

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({})},})
