vue进入页面时滚动条始终在底部代码实例

mounted () { this.scrollToBottom();},//每次页面渲染完之后滚动条在最底部updated:function(){ this.scrollToBottom();},methods:{ scrollToBottom: function () {  this.$nextTick(() => {	 var container = this.$el.querySelector(".chatBox-content-demo");  container.scrollTop = container.scrollHeight;  })}}

::-webkit-scrollbar { width: 5px; height: 5px;} ::-webkit-scrollbar-track-piece { background-color: rgba(0, 0, 0, 0.2); -webkit-border-radius: 6px;} ::-webkit-scrollbar-thumb:vertical { height: 5px; background-color: rgba(125, 125, 125, 0.7); -webkit-border-radius: 6px;} ::-webkit-scrollbar-thumb:horizontal { width: 5px; background-color: rgba(125, 125, 125, 0.7); -webkit-border-radius: 6px;}

在created()或者mounted () 里都可以 mounted () { this.$nextTick(() => { this._initScroll(); let allLi=this.$refs.chatcontheight.querySelectorAll("li"); this.chartScroll.scrollToElement(allLi[allLi.length-1],0); });},//每次页面渲染完之后滚动条在最底部updated:function(){  this.$nextTick(() => {this._initScroll();let allLi=this.$refs.chatcontheight.querySelectorAll("li");this.chartScroll.scrollToElement(allLi[allLi.length-1],0);  });},methods:{ _initScroll(){this.chartScroll=new BScroll(this.$refs.chatcontheight,{   click:true  })}} 结构<div ref="$refs.chatcontheight" style="overflow: hidden;">  <ul> <li></li>  </ul></div>
