使用：

@mouseenter="GlobalFunc.titleMouseOver($event,15)"
@mouseleave="GlobalFunc.titleMouseOut($event)"
>鼠标悬停[直接调用函数版本,设定行字数]</div>
<style>
.title_focus_toolTip {
z-index: 7;
position: absolute;
display: none;
min-width: 200px;
min-height: 50px;max-width: 200px;word-break: normal;
border-style: solid;
transition: left 0.4s cubic-bezier(0.23, 1, 0.32, 1),
top 0.4s cubic-bezier(0.23, 1, 0.32, 1);
background-color: rgba(50, 50, 50, 0.701961);
border-width: 0px;

效果：
定义一个div，作为弹框，需要显示传入内容即可
<div id="focus_toolTip" class="special_focus_toolTip" v-html="dispatchSystemAddressBookTopbody">
</div>
.special_focus_toolTip {
z-index: 7;

}
照成的原因是：悬停上去信息框div盖住了span标签，mouseover事件失效，mouseout事件生效，信息框消失。
信息框消失后鼠标又正好悬停在span标签上，mouseover事件生效，mouseout事件失效，信息框显示。。。一直无限循环就会看到一直闪烁的现象。
解决办法 ：在你需要显示的信息框上加上pointer-events: none
