标题中带有过滤器的 Bootstrap-vue b-table [英] Bootstrap-vue b-table with filter in header

问题描述

我有一个用 bootstrap-vue 生成的表，它显示了系统搜索的结果.

结果表向用户显示记录，用户可以对它们进行排序和过滤.

如何在使用 bootstrap-vue 元素生成的表头 下方添加搜索字段?

解决方案

您可以使用 top-row 槽来自定义您自己的第一行.请参阅下面的基本示例.

new Vue({el: '#app',数据: {过滤器:{ID: ''，由...发出: ''，发给:''},项目:[{id:1234,issuedBy:'Operator',issuedTo:'abcd-efgh'},{id:5678,issuedBy:'User',issuedTo:'ijkl-mnop'}]},计算:{过滤(){const 过滤 = this.items.filter(item => {返回 Object.keys(this.filters).every(key =>字符串(项目[键]).包括(this.filters[键]))})返回filtered.length >0 ?过滤:[{ID: ''，由...发出: ''，发给:''}]}}})

<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css"/><link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap-vue@latest/dist/bootstrap-vue.css"/><script src="https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.min.js"></script><script src="//unpkg.com/babel-polyfill@latest/dist/polyfill.min.js"></script><script src="//unpkg.com/bootstrap-vue@latest/dist/bootstrap-vue.js">;</脚本><div id="应用程序"><b-table striped show-empty :items="filtered"><template slot="top-row" slot-scope="{ fields }"><td v-for="字段中的字段" :key="field.key"><input v-model="filters[field.key]" :placeholder="field.label"></td></b-table>

注意:我使用了计算属性来过滤项目，而不是 b-table 中的 :filter 属性，因为它没有'如果过滤掉所有项目，包括您的自定义第一行，则不呈现行.这样我就可以在结果为空时提供一个虚拟数据行.

I have a table generated with bootstrap-vue that shows the results of a system search.

The Results Table shows the records to the user, and the user can sort them and filter them.

How can I add the search field underneath the table header <th> generated with the bootstrap-vue <b-table> element?

解决方案

You can use the top-row slot to customise your own first-row. See below for a bare-bones example.

new Vue({
  el: '#app',
  data: {
    filters: {
      id: '',
      issuedBy: '',
      issuedTo: ''
    },
    items: [{id:1234,issuedBy:'Operator',issuedTo:'abcd-efgh'},{id:5678,issuedBy:'User',issuedTo:'ijkl-mnop'}]
  },
  computed: {
    filtered () {
      const filtered = this.items.filter(item => {
        return Object.keys(this.filters).every(key =>
            String(item[key]).includes(this.filters[key]))
      })
      return filtered.length > 0 ? filtered : [{
        id: '',
        issuedBy: '',
        issuedTo: ''
      }]
    }
  }
})

<div id="app">
<b-table striped show-empty :items="filtered">
  <template slot="top-row" slot-scope="{ fields }">
    <td v-for="field in fields" :key="field.key">
      <input v-model="filters[field.key]" :placeholder="field.label">
    </td>
  </template>
</b-table>
</div>

Note: I've used a computed property to filter the items instead of the :filter prop in b-table because it doesn't render rows if all the items are filtered out, including your custom first-row. This way I can provide a dummy data row if the result is empty.
