剧集数字兼容性显示

也就是根据盒子大小来排布,能排满就直接排列,否则显示...
思路就是获取外部盒子宽度,除以每个集数的宽度+marginRight,得出每一列最多排列的个数maxNum,然后根据:集数总和 > (maxNum*2),来决定是否显示省略号,剩下的就是判断某几个元素的marginRight是否为0(以免超过盒子宽度,导致不必要的换行),整个组件如下:
<template>
<ul class="episode-ul" @click="onClick">
<template v-if="isFold">
<li
v-for="num in maxNum - 1"
:key="'fold' + num"
:data-num="num"
class="video-episode-li"
:class="{ active: selectNum === num }"
>
{{ num }}
<videoTypeIcon
:is-free-limit="list[num - 1].isFreeLimit === 1"
:is-vip-saction="list[num - 1].isVipSaction === 1"
/>
</li>
<li class="video-episode-li video-episode-more" data-num="more">…</li>
<li
v-for="num in leftNumArray"
:key="'last' + num"
:data-num="episodeLen - num"
:class="[{ active: selectNum === episodeLen - num },{'fold-item':num===0}]"
class="video-episode-li"
>
{{ episodeLen - num }}
<videoTypeIcon
:is-free-limit="list[episodeLen - num - 1].isFreeLimit === 1"
:is-vip-saction="list[episodeLen - num - 1].isVipSaction === 1"
/>
</li>
</template>
<template v-else>
<li
v-for="(item, index) in list"
:key="index"
:class="[{ active: selectNum === item.num },{'fold-item':(index===maxNum-1)||(index===2*maxNum-1)}]"
:data-num="item.num"
class="video-episode-li"
>
{{ item.num }}
<videoTypeIcon
:is-free-limit="item.isFreeLimit === 1"
:is-vip-saction="item.isVipSaction === 1"
/>
</li>
</template>
</ul>
