我的vue组件脚本如下:
<template>
...
<b-card-group deck v-for="row in formattedClubs">
<b-card v-for="club in row"
img-src="http://placehold.it/130?text=No-image"
img-alt="Img"
img-top>
<h4 class="card-title"
@mouseenter="club.truncate = false"
@mouseleave="club.truncate = true">
<template v-if="club.truncate">{{trucateText(club.description)}}</template>
<template v-else>{{club.description}}</template>
</h4>
<p class="card-text">
{{club.price}}
</p>
<p class="card-text">
{{club.country}}
</p>
<div slot="footer">
<b-btn variant="primary" block>Add</b-btn>
</div>
</b-card>
</b-card-group>
...
</template>
<script>
export default {
data: function () {
return {
clubs: [
{id:1, description:'chelsea is the best club in the world and chelsea has a great player', price:1000, country:'england'},
{id:2, description:'liverpool has salah', price:900, country:'england'},
{id:3, description:'mu fans', price:800, country:'england'},

{id:9, description:'barcelona in the spain', price:200, country:'spain'},
{id:10, description:'psg buys neymar at a fantastic price', price:100, country:'france'}
]
}
},
computed: {
formattedClubs() {
return this.clubs.reduce((c, n, i) => {
if (i % 4 === 0) c.push([]);
c[c.length - 1].push(n);
this.$set(n, 'truncate', true);
return c;
}, []);
}
},
methods: {
trucateText (value) {
const length = 30;
return value.length <= length ? value : value.substring(0, length) + "...";
}
}
}
</script>
如果执行了脚本,则视图如下:
如果我将描述悬停,则结果如下:
它会改变箱子列表的高度
我该如何解决这个问题?

我们可以看到您正在使用bootstrap-vue。很好,因此您可以使用v-b-tooltip directive并让自己控制悬停行为。由于您不再需要为每个俱乐部单独跟踪它,因此可以从计算的属性formattedClubs
中删除该相对属性:
this.$set(n, 'truncate', true); // Remove this line.
现在,将模板更新为仅在需要截断的情况下才使用指令:
<h4 class="card-title"
v-if="club.description.length > 30"
v-b-tooltip.hover.bottom
:title="club.description">
{{trucate(club.description)}}
</h4>
<h4 v-else>{{club.description}}</h4>
当然,您现在可以按照想要覆盖正确的Boostrap样式的方式设置样式:
.tooltip.show {
opacity: 1;
}
.tooltip-inner {
background: #fff;
color: #000;
padding: .5em 1em;
border: 1px solid #bbb;
box-shadow: 0 3px 8px rgba(0, 0, 0, .15);
}
.tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow, .tooltip.bs-tooltip-bottom .arrow {
position: relative;
background: #fff;
top: 1px;
width: 16px;
}
.tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .tooltip.bs-tooltip-bottom .arrow::before, .tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow::after, .tooltip.bs-tooltip-bottom .arrow::after {
bottom: 0;
left: 50%;
border: solid transparent;
content: " ";
height: 0;
width: 0;
position: absolute;
pointer-events: none;
}
.tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow::after, .tooltip.bs-tooltip-bottom .arrow::after {
border-color: rgba(255, 255, 255, 0);
border-bottom-color: #fff;
border-width: 8px;
margin-left: -8px;
}
.tooltip.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .tooltip.bs-tooltip-bottom .arrow::before {
border-color: rgba(187, 187, 187, 0);
border-bottom-color: #bbb;
border-width: 9px;
margin-left: -9px;
}

我只需要用工具提示组件包装截断的文本即可。您可以将全文作为道具传递给该组件。
悬停时,您可以使用@mouseover
显示工具提示,并使用@mouseleave
将其删除。
工具提示本身可以是带有max-width
的绝对位置元素。我不会将所有内容都打出来,但这应该可以帮助您入门。
