微信小程序实现拉链式的滑动验证
本文实例为大家分享了微信小程序实现拉链式滑动验证的具体代码,供大家参考,具体内容如下
view结构
<view style="position: relative;height:90rpx"> <movable-area class="content" style="width:{{area_width}}rpx"> <movable-view class='box' style='width:{{box_width}}rpx' friction="{{100}}" direction="horizontal" x="{{x}}" damping="{{500}}" bindchange="drag" bindtouchend="dragOver"> <view class='movable-icon'></view> </movable-view> </movable-area> <view class="black" style="width:{{text}}rpx"></view> <view class="movable_text"> 向右滑动验证</view> </view>
wxss样式
.content { position: absolute; right: 50rpx; height: 90rpx; background-color: #4fca9b; color: white; border-radius: 50px; display: flex; justify-content: center; align-items: center; font-size: 16px; } .box { z-index: 45; height: 90rpx; background-color: transparent; border-radius: 50rpx; display: flex; justify-content: center; align-items: center; } .movable-icon { z-index: 40; width: 120rpx; height: 90rpx; background-color: blue; border-radius:50rpx; background-size: 100% 100%; } .black { z-index: 10; height: 90rpx; background-color: #acacac; position: absolute; right: 50rpx; border-radius: 50px; } .movable_text { font-size: 32rpx; z-index: 30; position: absolute; left: 50%; transform: translate(-50%, -50%); color: white; top: 50%; }
js逻辑
Page({ data: { // 滑块 x: 0, area_width: 620, //可滑动区域的宽,单位是百分比,设置好后自动居中 text: 620, box_width: 120, //滑块的宽,单位是 rpx maxNum: 620; coord: '', }, onShow(){ this.data.rpx = this.getRpx() // px与rpx的转换 }, getRpx(){ var winWidth = wx.getSystemInfoSync().windowWidth; return 750 / winWidth; }, // 滑块 drag(e) { let rpx = this.data.rpx var coord = e.detail.x; let wid = this.data.maxNum - (coord) * rpx this.setData({ coord: coord, text: wid }) }, // 滑块验证 dragOver(e) { let rpx = this.data.rpx if ((this.data.coord) * rpx + this.data.box_width+5>= this.data.maxNum) { //验证成功之后的代码 } else { this.setData({ x: 0, }) } },
这里是用了微信小程序的组件可移动的视图容器,有两层容器的嵌套,通过滑块的滑动,改变第二层的宽度,以达到拉链式的效果。
