vue修改自带的title属性样式 title属性样式修改办法

1.定义id=‘title’ :data-title=“itemss.contactsCallTime2” 这个值

<div class="grid-content1 bg-purple-light"id="title" onmouseover="onMouseHover(event)" onmouseout="onMouseOut()" :data-title="itemss.contactsCallTime2">{{itemss.contactsCallTime2 | filterFun}}</div>

2.定义οnmοuseοver=“onMouseHover(event)” οnmοuseοut=“onMouseOut()” 鼠标事件

鼠标经过时插入样式，鼠标离开时清除样式。

onMouseHover(ev) {document.styleSheets[0].insertRule('#title::before { left: '+ ev.pageX +'px }', 0);document.styleSheets[0].insertRule('#title::after { left: '+ ev.pageX +'px }', 0);},onMouseOut() {document.styleSheets[0].deleteRule(0);document.styleSheets[0].deleteRule(0);},
