所以我一直在草拟算法,看看它是如何工作的。因为坦率地说,没有任何东西可以正常工作。基本上硬编码的HTML看起来像这样:
<div class="row">
<div class="column">
<a href="products.html#drinks"><div id="drinks">
<h2>Drinks</h2>
</div></a>
</div>
<div class="column">
<a href="products.html#preppedfood"><div id="preppedfood">
<h2>Prepped Food</h2>
</div></a>
</div>
<div class="column">
<a href="products.html#coffee"><div id="coffee">
<h2>Coffee Machines</h2>
</div></a>
</div>
<div class="column">
<a href="products.html#snacks"><div id="snacks">
<h2>Snacks</h2>
</div></a>
</div>
</div>
<div class="row">
<div class="column">
<a href="products.html#nuts"><div id="nuts">
<h2>Nuts of All Kinds</h2>
</div></a>
</div>...till the last div class="row" and it's column divs
所以HTML工作正常,这是一个截图: This is how I want it to look!
但是使用VueJS以便我可以“干掉”我的标记,我在Prods.vue组件中使用这样的v-for指令。这是模板标记:
<div class="row" v-for="(data, index) in images" v-bind:key="data" v-if="data.ImageId%4 == 0">
<h1>{{index}}</h1>
<div
class="column"
v-for="data in images"
v-bind:key="data"
v-if="computedIndex(index) *4 >= index && index < (computedIndex(index)+1) / 4"
v-lazy-container="{ selector: 'data' }"
>
<a :href="'products/#'+data.Name">
<h4>{{data.H2}}</h4>
<img :src="'../../../static/products/'+data.Name+'.png'" :alt="data.Name+'.png'" />
</a>
</div>
</div>
脚本:
<script>
import Prods from '../../../other/jsons/products.json'
import VueLazyload from 'vue-lazyload'
export default {
data() {
return {images: Prods}
},
methods: {
computedIndex(index) {
return Math.trunc(index/4)
}
}
}
//v-for in row
//v-for in column
</script>
这就是出现的情况: enter image description here

对于我来说,计算数组的形状以适合您的DOM似乎更直接,而不是使用索引:
computed:
imageRows () {
return this.images.reduce((acc, n, i) => {
i % 4 ? acc[acc.length - 1].push(n) : acc.push([n])
return acc
}, [])
}
要使用这样的东西:
<table>
<tr v-for="(imageRow, i) in imageRows" :key="i">
<td v-for="image in imageRow" :key="image">
<foo/>
</td>
</tr>
</table>
(您的数据似乎是我的表格,所以我将此示例显示为<table>
,但如果您愿意,可以将其替换为<div>
,当然。)
