先看效果是否是自己需要的
实现步骤：
1.整个布局用作为根节点包裹所有view，并动态绑定scroll-view的scroll-y属性
2.样式文件中设置Page的overflow-y属性值为hidden
3.样式文件中设置scroll-view的height属性值为100%
4.打开自定义弹窗的点击事件中，更改isScroll的值为false，关闭弹窗的点击事件中，更改isScroll的值为true
JS:
Page({ /** * 页面的初始数据 */ data: { arrayData: null, dialogData: null, isDialogShow: false, isScroll: true }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { //构建测试数据 let data = new Array(); let dialog = new Array(); for (let i = 0; i < 25; i++) { data[i] = '我是测试-----------' + i; dialog[i] = { name: '我是弹窗-' + i, isSelected: false }; } this.setData({ arrayData: data, dialogData: dialog }); }, /** * 显示、关闭弹窗 */ showDialog: function (e) { var currentStatu = e.currentTarget.dataset.statu; console.log('currentStatu:', currentStatu); //关闭 if (currentStatu == "close") { this.setData({ isDialogShow: false, isScroll: true }); } // 显示 if (currentStatu == "open") { this.setData({ isDialogShow: true, isScroll: false }); } } })
wxml：
<button>做点什么</button> <scroll-view scroll-y="{{isScroll}}"> <view> <view> <view wx:for="{{arrayData}}" wx:key="" bindtap="showDialog" data-statu="open"> <input value="{{item}}" disabled /> </view> </view> </view> </scroll-view> <!--测试弹窗--> <view bindtap="showDialog" data-statu="close" wx:if="{{isDialogShow}}"></view> <!--dialog--> <view wx:if="{{isDialogShow}}"> <view> <text>我是弹窗</text> </view> <view wx:for="{{dialogData}}"> <view> <text>{{item.name}}</text> </view> </view> </view>
wxss：
