這篇文章主要介紹了uniapp幾行代碼解決滾動穿透問題,本文結(jié)合實例代碼給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

具體的解決方式：

<template >
  <view class="" >
    <page-meta :page-style="spanStyle"></page-meta>
  </view>
</template>
<script >
  export default {
    data() {
      return {
        spanStyle:"overflow:auto"
      }
    },
    methods: {
      mask(data){
        //當(dāng)蒙層彈起時，固定界面禁止?jié)L動，當(dāng)蒙層關(guān)閉時，允許滾動
        if(data){
          this.spanStyle="overflow:hidden";
        }else{
          this.spanStyle="overflow:auto";
        }
      }
    }
  }
</script >

項目實戰(zhàn)：

<template>
	<page-meta :page-style="'overflow:'+(searchPopupVisible?'hidden':'visible')" />
	
	<!--區(qū)域選擇-->
	<div class="d-toolbox cf">
		<a href="javascript:;" rel="external nofollow"  rel="external nofollow"  @click="showPopup" class="a-area" :hover="selectText!='區(qū)域'" :isOne="isOne">{{selectText}}</a>
		
		<u-popup :show="searchPopupVisible" mode="bottom" @close="searchPopupVisible = false" class="d-searchPopup cf">
			<div class="d-searchPopupBox cf">
				<strong>選擇區(qū)域</strong>
				<div v-if="resultData.length > 0">

					</scroll-view>
				</div>
				<div v-else>
					<em>暫無數(shù)據(jù)</em>
				</div>
				<a href="javascript:;" rel="external nofollow"  rel="external nofollow"  @click="searchPopupVisible = false">取消</a>
			</div>
		</u-popup>
	</div>
</template>
 
<script>
	export default {

		watch:{
			region_id(val){
				this.selectText = val == '' ? '區(qū)域' : this.resultData.find(item=>item.region_id == val).region_name
			},
		},
		mounted() {
			this.storage_authorInfo = uni.getStorageSync('storage_authorInfo') ? JSON.parse(uni.getStorageSync('storage_authorInfo')) : {};
			this.resultData = this.storage_authorInfo.Store;
			this.resultData.unshift({'region_name':'全部','region_id':''});
			//只有一個區(qū)域的特殊情況
			if(this.resultData.length === 2){
				this.isOne = true
				this.selectText = this.resultData[1].region_name
			}
			
		},
		methods: {
			showPopup(){

			}
		}
		
	}

PS：uniapp解決滾動條問題

在App.vue的style中寫上

/* 解決小程序和app滾動條的問題 */
/* #ifdef MP-NEIXIN 11 APP-PLUS */

::-webkit-scrollbar {
display: none;
width: 0 !important;
height: 0 !important;
-webkit-appearance: none;
background: transparent;
color: transparent;
}

/* #endif */
/* 解決H5的問題 */
/* #ifdef H5 */

uni-scroll-view .uni-scroll-view::webkit-scrollbar {
/* 隱藏滾動條,但依舊具備可以滾動的功能 */
display: none;
width: 0 !important;
height: 0 !important;
-webkit-appearance: none;
background: transparent;
color: transparent;
}
