记一次Vue项目解决微信浏览器下拉“网页由xxx提供，QQ浏览器

外层html、body等设为不可滚动,ps:#app为vue项目基础DOM;.wx-pages为App.vue内部路由

html,body,#app,.wx-pages{
    padding: 0;
      margin: 0;
    height: 100%;
    overflow: hidden;
    -webkit-overflow-scrolling: touch;
}

在public/index.html里移除touchmove事件

document.body.addEventListener('touchmove', function(e) {
    e.preventDefault(); 
}, {
    passive: false
});

写Scroll组件

<style scoped="scoped">
    .w-scroll {
        height: 100%;
        overflow: auto;
        -webkit-overflow-scrolling: touch;
    }
</style>
<template>
    <div ref="scroll" class="w-scroll">
        <slot></slot>
    </div>
</template>

<script>
    export default {
        name: 'scroll',
        data() {
            return {}
        },
        computed: {},
        mounted() {
            this.wScroll(this.$refs.scroll);
        },
        methods: {
            wScroll(elem) {
                var startX = 0,startY = 0;
                document.addEventListener('touchstart', function(evt) {
                    var touch = evt.touches[0]; 
                    startX = Number(touch.pageX); 
                    startY = Number(touch.pageY); 
                });
                elem.addEventListener('touchmove', function(ev) {
                    var _point = ev.touches[0],
                        _top = elem.scrollTop;
                    var _bottomFaVal = elem.scrollHeight - elem.offsetHeight;
                    //console.log(_top + ":" + _bottomFaVal + ":" + elem.offsetHeight + ":" + elem.scrollHeight);
                    if(_top === 0) {
                        if(_point.clientY > startY) {
                            ev.preventDefault();
                        } else {
                            ev.stopPropagation();
                        }
                    } else if(_top === _bottomFaVal) {
                        elem.scrollTop--;
                    } else if(_top > 0 && _top < _bottomFaVal) {
                        ev.stopPropagation();
                    } else {
                        ev.preventDefault();
                    }
                }, {
                    passive: false
                });
            }
        },
    }
</script>

在需要滚动的模块中使用Scroll包起来

<style scoped>
</style>

<template>
    <Scroll style="margin-bottom: 20px;background-color: #f2f2f2;">
        内容
    </Scroll>
</template>

<script>
    import Scroll from '@/components/Scroll';
    export default {
        components:{
            Scroll
        },
    }
</script>

可以直接加到App.vue里面，可以直接解决全局此问题

<template>
    <Scroll id="app">
        <router-view class="wx-pages" />
    </Scroll>
</template>

至此，完成，在微信浏览器中下拉不会再出现“网页由XXX提供，QQ浏览器X5内核提供技术支持”
