Use WeChat applet to implement sliding menu effect
WeChat applet, as a tool that is rapidly developed and widely used, provides us with a variety of ways to implement sliding menus effect method. This article will show you a simple and practical implementation method to help you easily add sliding menu effects in development.
<!-- 页面布局 --> <view class="container"> <view class="content"> <view class="item" wx:for="{{list}}" wx:key="{{index}}" catchtouchmove="catchTouchMove"> {{item}} </view> </view> </view>
In the above code, we use the wx:for
directive to loop through rendering menu items and add catchtouchmove to each menu item Event, used to trigger the effect of the sliding menu.
/* 页面样式 */ .container { width: 100%; height: 100vh; background-color: #f2f2f2; overflow: hidden; } .content { width: 100%; height: 100%; overflow-x: hidden; overflow-y: auto; } .item { width: 100%; height: 100px; line-height: 100px; text-align: center; background-color: #fff; border-bottom: 1px solid #ccc; } /* 滑动菜单样式 */ .item-move { transition: transform .3s; transform: translateX(0); } .item-remove { transform: translateX(-100%); }
In the above code, we define the container, content and style of each menu item. At the same time, we use the transform
attribute combined with the transition effect to achieve the animation effect when the menu slides.
Page({ data: { list: ['菜单1', '菜单2', '菜单3'], startX: 0 }, catchTouchMove: function(ev) { if (ev.touches.length == 1) { this.setData({ startX: ev.touches[0].clientX }) } }, catchTouchEnd: function(ev) { const index = ev.currentTarget.dataset.index; const moveX = ev.changedTouches[0].clientX - this.data.startX; if (moveX < -60) { const list = this.data.list; list.splice(index, 1); this.setData({ list: list }) } } })
In the above code, we define a catchTouchMove
event handler function to record the coordinates when the sliding starts. Subsequently, we wrote a catchTouchEnd
event handling function to determine whether the menu item needs to be deleted when the sliding ends.
<view class="item" wx:for="{{list}}" wx:key="{{index}}" catchtouchmove="catchTouchMove" bindtap="catchTouchEnd" data-index="{{index}}"> {{item}} </view>
In the above code, we use the bindtap
event binding mechanism to bind the sliding end event processing method to the menu item. Implemented the interactive effect of deleting menu items.
So far, we have completed the implementation of the sliding menu effect in the WeChat applet. Through simple layout, style setting and event handling, we can easily add a sliding menu effect similar to that in WeChat to the mini program page.
Summary:
This article introduces the detailed steps on how to use WeChat applet to achieve the sliding menu effect, including layout structure, style setting, event processing and adding interactive effects. I hope this article will be helpful to your development work, and I wish you success in WeChat mini program development!
