微信小程序实现滑块验证
本文实例为大家分享了微信小程序实现滑块验证的具体代码,供大家参考,具体内容如下
思路:
1.手指按住 并且 还能 滑动
2.滑动到一定的距离 进行判断
百度微信开发者文档 : 使用 movable-view的可移动区域。 结合 movable-view
wxml代码
<movable-area class="content" style="width:{{area_width}}%">拖动滑块验证 <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>
wxjs
var coord; //声明 全局变量 // data里面的数据 x: 0, area_width: 85, //可滑动区域的宽,单位是百分比,设置好后自动居中 box_width: 120, //滑块的宽,单位是 rpx maxNum: 0, // 函数方法 drag(e) { var that = this; coord = e.detail.x; //根据bindchange 事件获取detail的x轴 }, dragOver(e) { //根据触摸 手指触摸动作结束 判断 当前的x轴 是否大于预设值的值 var that = this; if (coord >= that.data.maxNum) { wx.showToast({ title: '验证成功', icon: 'success', duration: 2000 }) //验证成功之后的代码 } else { // 如果不大于 则设置 x周的距离为0 that.setData({ x: 0, }) } }, onLoad: function (e) { var that = this; wx.getSystemInfo({ //获取系统信息 设置预设值 success: function (res) { console.log(res.windowWidth); var n = Math.floor(res.windowWidth * that.data.area_width / 100 - that.data.box_width / 2) console.log(n) that.setData({ maxNum: n, }) } }) },
