本文为大家分享了微信小程序自定义弹窗滚动与页面滚动冲突的解决方法，供大家参考，具体内容如下

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 class="rootView">
  <view class="inTable">
   <view wx:for="{{arrayData}}" wx:key="" class="unitItemLeft" bindtap="showDialog" data-statu="open">
    <input class="baseItemWithBorder" value="{{item}}" disabled />
   </view>
  </view>
 </view>
</scroll-view>


<!--测试弹窗--> 
<view class="dialogMarsk" bindtap="showDialog" data-statu="close" wx:if="{{isDialogShow}}"></view> 
 <!--dialog-->
<view class="dialog" wx:if="{{isDialogShow}}">
 <view class="appreciationTitle">
  <text style="font-size:24px;">我是弹窗</text>
 </view>
 <view wx:for="{{dialogData}}" class="appreciationTable">
  <view class="unitItemLeft">
   <text class="baseItemWithBorder">{{item.name}}</text>
  </view>
 </view>
</view>
