小编这次要给大家分享的是微信小程序如何实现弹出层效果，文章内容丰富，感兴趣的小伙伴可以来了解一下，希望大家阅读完这篇文章之后能够有所收获。

先看下效果图吧

其实这个效果实现起来很简单，就是通过三目运算符来控制遮罩层的显示和隐藏

贴代码了：

规则按钮：

<text class='rule' bindtap='showRule'>规则</text>

遮罩层：我这个数据是从后台拿来动态渲染到页面的

<!-- 规则提示 --> <view class="ruleZhezhao {{isRuleTrue&#63;'isRuleShow':'isRuleHide'}}"> <view class='ruleZhezhaoContent'> <view class='ruleZhezhaoText' wx:for='{{rule}}' wx:for-index='index'> <text>{{index+1}}</text> <text>{{item}}</text> </view> <image src='../../images/rule-hide.png' class='ruleHide' bindtap='hideRule'></image> </view> </view> <!-- end -->

css:

/* 规则提示层 */.isRuleShow{ display: block;}.isRuleHide{ display: none;}.ruleZhezhao{ height: 100%; width: 100%; position: fixed; background-color:rgba(0, 0, 0, .5); z-index: 2; top: 0; left: 0;}.ruleZhezhaoContent{ padding: 20rpx 0; width: 80%; background: #e1d2b1; margin: 40% auto; border-radius: 20rpx; display: flex; flex-direction: column; justify-content: space-around; align-items: center; position: relative;}.ruleZhezhaoText{ width: 80%; font-size: 30rpx; color: #856d5f; display: flex; flex-direction: row; align-items: center; margin: 25rpx 0 25rpx 0;}.ruleZhezhaoText text:nth-child(1){ color: #fff; font-size: 40rpx; height: 60rpx; width: 60rpx; background: #664a2c; display: block; text-align: center; line-height: 60rpx; border-radius: 30rpx; margin-right: 10rpx;}.ruleZhezhaoText text:nth-child(2){ flex-wrap:wrap; width: 80%;}.ruleHide{ height: 60rpx!important; width: 60rpx!important; position: absolute; top: -20rpx; right: -20rpx;}.rule{ display: block; border: 1px solid #fff; width: 100rpx; text-align: center; line-height: 60rpx; color: #fff; height: 60rpx; font-size: 30rpx; border-radius: 30rpx; position: absolute; top: 10%; right: 5%;}/* end */

点击规则按钮：

//打开规则提示 showRule: function () { this.setData({ isRuleTrue: true }) },

点击关闭按钮：

//关闭规则提示 hideRule: function () { this.setData({ isRuleTrue: false }) },
