可以使用计算属性来计算出每列所占每行总数的整数比。具体实现步骤如下:
1. 在data中定义总数和每列的数量:
```
data() {
return {
total: 20,
columnCount: 4
}
}
```
2. 在计算属性中计算每列所占每行总数的整数比:
```
computed: {
columnRatio() {
const { total, columnCount } = this;
const columnTotal = Math.floor(total / columnCount);
const remainder = total % columnCount;
const ratios = Array(columnCount).fill(columnTotal);
for (let i = 0; i < remainder; i++) {
ratios[i]++;
}
return ratios;
}
}
```
3. 在模板中使用v-for循环渲染数据,并将每列所占每行总数的整数比作为样式flex-basis的值:
```
<template>
<div class="container">
<div v-for="(ratio, index) in columnRatio"
:key="index"
class="column"
:style="{ flexBasis: ratio + '%' }">
{{ ratio }}
</div>
</div>
</template>
```
完整代码示例如下:
```
<template>
<div class="container">
<div v-for="(ratio, index) in columnRatio"
:key="index"
class="column"
:style="{ flexBasis: ratio + '%' }">
{{ ratio }}
</div>
</div>
</template>
<script>
export default {
data() {
return {
total: 20,
columnCount: 4
}
},
computed: {
columnRatio() {
const { total, columnCount } = this;
const columnTotal = Math.floor(total / columnCount);
const remainder = total % columnCount;
const ratios = Array(columnCount).fill(columnTotal);
for (let i = 0; i < remainder; i++) {
ratios[i]++;
}
return ratios;
}
}
}
</script>
<style>
.container {
display: flex;
width: 100%;
height: 100%;
}
.column {
display: flex;
justify-content: center;
align-items: center;
border: 1px solid #ccc;
}
</style>
```
