HTML:
<div ref="page"></div>
JS:
data(){ return{ clientHeight:'', } } mounted(){ this.clientHeight = `${document.documentElement.clientHeight}`;//获取浏览器可视区域高度 let that = this; window.onresize = function(){ this.clientHeight = `${document.documentElement.clientHeight}`; if(that.$refs.page){ that.$refs.page.style.minHeight = clientHeight - 100 + 'px'; } } } watch:{ clientHeight(){ //如果clientHeight 发生改变,这个函数就会运行 this.changeFixed(this.clientHeight) } } methods:{ changeFixed(clientHeight){ if(this.$refs.page){ this.$refs.page.style.minHeight = clientHeight -100 + 'px'; } } }
