作者:風灬雲
这篇文章主要介绍了Vue实现监听dom节点宽高变化方式,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教
原生js方法
该方法适用所有vue项目,原生js开发的思维
<div ref="datas"> <div class="scroll_box" ref="scroll" style="width:20%;height: 20%;overflow:scroll;position: absolute;left: 0;top: 0;background-color: #000;"> <div class="scroll_child" style="width:300%;height: 300%;"></div> </div> <div class="scroll_box2" ref="scroll2" style="width:20%;height: 20%;overflow:scroll;position: absolute;left: 0;top: 0;background-color: #000;"> <div class="scroll_child" style="width:300px;height: 300px;"></div> </div> </div>
mounted(){ // 监听节点宽高变小 (this.$refs.scroll as HTMLElement).scrollTop = 1000; (this.$refs.scroll as HTMLElement).scrollLeft = 1000; (this.$refs.scroll as HTMLElement).addEventListener('scroll', () => { this.width = ((this.$refs.datas as Vue).$el as HTMLElement).offsetWidth; (this.$refs.scroll2 as HTMLElement).scrollTop = 1000; (this.$refs.scroll2 as HTMLElement).scrollLeft = 1000; }); // 监听节点宽高变大 (this.$refs.scroll2 as HTMLElement).scrollTop = 1000; (this.$refs.scroll2 as HTMLElement).scrollLeft = 1000; (this.$refs.scroll2 as HTMLElement).addEventListener('scroll', () => { this.width = ((this.$refs.datas as Vue).$el as HTMLElement).offsetWidth; (this.$refs.scroll as HTMLElement).scrollTop = 1000; (this.$refs.scroll as HTMLElement).scrollLeft = 1000; }) }
element-ui element-resize-detector插件
vue + element 开发项目时的首选,简单有效
<div ref="datas"></div>
mounted(){ let erd = elementResizeDetectorMaker(); erd.listenTo((this.$refs.datas as Vue).$el, (element: HTMLElement) => { this.width = element.offsetWidth; }) }
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
