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