如何使用 v-for 使用 vue.js 渲染表格 [英] How to use v-for to render a table using vue.js

问题描述

我有一个看起来像这样的数组:

sales = [[{'Year': 2018, 'Month': 01, 'Sale';512}, {'Year': 2018, 'Month': 02, 'Sale';1025}, ....],[{'Year': 2017, 'Month': 01, 'Sale';155}, {'Year': 2017, 'Month': 02, 'Sale';12}, ....]]

我想使用 vue 在表格中显示它:

<头><tr><th>#</th><th>2018</th><th>2017</th></tr></thead><tr v-for="(sale,i) in sales" :key="i"><th scope="row">{{ ???}}</th>//月<td>{{ ???}}</td>//当前年份.销售<td>{{ ???}}</td>//上一年.销售</tr></tbody>

不幸的是，我不知道如何遍历我的销售数组以显示在当前年份和上一年的每个表行销售中.

解决方案

<table class="table table-striped"><头><tr><th>#</th><th>2018</th><th>2017</th></tr></thead><tr v-for="(sale,i) in sales[0]" :key="i"><th scope="row">{{ sale.Month }}</th><td>{{ sale.Sale }}</td><td>{{ sales[1][i].Sale }}</td></tr></tbody>
新的 Vue({el: "#app",数据: {销售量: [[{'Year': 2018, 'Month': 01, 'Sale': 512}, {'Year': 2018, 'Month': 02, 'Sale': 1025}],[{'Year': 2017, 'Month': 01, 'Sale': 155}, {'Year': 2017, 'Month': 02, 'Sale': 12}]]}})

I've an array that look like this:

sales = [
 [{'Year': 2018, 'Month': 01, 'Sale'; 512}, {'Year': 2018, 'Month': 02, 'Sale'; 1025}, ....],
 [{'Year': 2017, 'Month': 01, 'Sale'; 155}, {'Year': 2017, 'Month': 02, 'Sale'; 12}, ....]
]

i would like to show it in a table using vue:

<table class="table table-striped">
  <thead>
    <tr>
      <th>#</th>
      <th>2018</th>
      <th>2017</th>
    </tr>
  </thead>
  <tbody>
    <tr v-for="(sale,i) in sales" :key="i">
       <th scope="row">{{ ??? }}</th> //Month
       <td>{{ ??? }}</td> //currentYear.Sale
       <td>{{ ??? }}</td> //previousYear.Sale
    </tr>
   </tbody>
</table>

unfortunately i don't know how to iterate through my sales array to show in every table row sale of the current year and the previous year.

解决方案

<div id="app">
  <table class="table table-striped">
  <thead>
    <tr>
      <th>#</th>
      <th>2018</th>
      <th>2017</th>
    </tr>
  </thead>
  <tbody>
    <tr v-for="(sale,i) in sales[0]" :key="i">
       <th scope="row">{{ sale.Month  }}</th>  
       <td>{{ sale.Sale }}</td> 
       <td>{{ sales[1][i].Sale }}</td>  
    </tr>
   </tbody>
</table>
</div>

new Vue({
  el: "#app",
  data: {
    sales: [
        [{'Year': 2018, 'Month': 01, 'Sale': 512}, {'Year': 2018, 'Month': 02, 'Sale': 1025}],
            [{'Year': 2017, 'Month': 01, 'Sale': 155}, {'Year': 2017, 'Month': 02, 'Sale': 12}]
    ]
  } 
})
