在vue中通过flex布局实现css的s型结构
通过数组截取循环布局，奇数行从左到右，在偶数行从右到左实现s型结构
主要内容分为三部分
中间内容部分
数据格式
js
items: [
{
nodeList: [1, 2, 3, 4, 5, 6]
},
{
nodeList: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
}, {
nodeList: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]
},
{
nodeList: [1, 2, 3, 4]
}
],
js
<template>
<a-row class="row" id="row" :class="alignItem(index)" :style="styleRow(index)">
<template v-for="(ite,inde) in it">
<a-col :xxl="4" :xl="6" :lg="8" :md="12">
<div class="lineBg" :style="{height: lineHeight+'px'}"
:class="{
'lineBorderLeft':it.length<row && inde===0 && index!=0 && inde!=it.length-1 && index%2!=0 || (item.nodeList.length===row*index+1 && index % 2 !== 0),
'lineBorderRight':(it.length<row && inde==it.length-1 && index%2==0)}">
<div class="line-title">
<div class="boxGrey">{{ ite }}</div>
</div>
</div>
<template>
<div class="item">
<div>
row:{{ row }}<br/>
it:{{ it.length }}<br/>
index:{{ index }}<br/>
</div>
</div>
</template>
<!-- 半圆的时候设置占位 -->
<div v-if="!hasRightAngle" :style="{height: lineHeight+'px'}"></div>
</a-col>
</template>
</a-row>
</template>
computed:{
styleRow() {
return function (index) {
if (index > 0) {
return {
marginTop: !this.hasRightAngle ? `-${this.lineHeight}px` : 0
}
}
}
},
alignItem() {
return function (index) {
return index % 2 !== 0 ? 'justify-end' : ''
}
},
}两端拼接的直接和半圆处理
linexx-round-r 和 linexx-round-l 代表拐角处的半圆处理
linexx-l和linexx-r两端的直角
可以切换为直角和半圆
js
Vue.component('linexx-round-r', {
template: `

},
}
})
Vue.component('linexx-l', {
template: `

<div v-else style="width: 25px"></div>
</template>
</div>`,
props: ['it', 'item', 'index', 'row'],
inject: ['splitArrayByLength'],
})顶点处理
判断有点复杂 应该还可以优化优化
