使用 Alpine JS 创建动态表

本文探讨了使用轻量级 javascript 框架 alpine js 创建动态表。我们将把这个过程分为三个部分：页眉、正文和页脚，重点关注基本场景和复杂场景。

配置：

1. html 结构： 我们从一个带有 x-data 指令的基本 html 元素 () 开始。该指令将反应数据绑定到元素。
2. javascript 数据： 我们在 html 之外定义一个空的 javascript 对象（数据）来保存我们的表数据。

初始代码如下：


<div x-data="data"></div><script>let data = {}</script>

标头

<thead class="sticky top-0 z-10 text-gray-700 bg-gray-50 dark:bg-gray-700 dark:text-gray-400">  <template x-for="row in table.customheader">    <tr>        <template x-for="col in row">            <th class="px-4 font-semibold text-left border-b py-1.5"                x-init="col.attr && object.keys(col.attr).foreach(e => $el.setattribute(e, col.attr[e]))">                <div class="flex items-center justify-center">                    <span x-html="col.title" class="whitespace-nowrap"></span>                </div>            </th>        </template>    </tr>  </template></thead>

let data = {  table: {      customheader: [          [              { title: 'city', attr: { rowspan: 2 }, class: 'border-r border-t' },              { title: 'clothes', attr: { colspan: 3 }, class: 'border-r border-t' },              { title: 'accessories', attr: { colspan: 2 }, class: 'border-t' }          ],          [              { title: 'trousers', class: 'border-r' },              { title: 'skirts', class: 'border-r' },              { title: 'dresses', class: 'border-r' },              { title: 'bracelets', class: 'border-r' },              { title: 'rings' },          ]      ],  }}

身体

<tbody>    <template x-for="(row, idx) in table.data">        <tr class="border-b dark:border-gray-700">            <template x-for="(col, icol) in row.columns">                <td x-bind:class="{ [col.class]: !!col.class }" class="px-3 border-b border-gray-200">                    <div x-text="col.text"></div>                </td>            </template>        </tr>    </template></tbody>

这是我们要显示的数据：


data: [    { "city": "mandalay", "trousers": 79, "skirts": 16, "dresses": 14, "bracelets": 69, "rings": 99 },    { "city": "george town", "trousers": 68, "skirts": 24, "dresses": 90, "bracelets": 96, "rings": 48 },    { "city": "gent", "trousers": 26, "skirts": 60, "dresses": 67, "bracelets": 5, "rings": 43 },    { "city": "mombasa", "trousers": 34, "skirts": 62, "dresses": 18, "bracelets": 75, "rings": 78 },    { "city": "lyon", "trousers": 13, "skirts": 33, "dresses": 12, "bracelets": 0, "rings": 17 },    { "city": "vancouver", "trousers": 82, "skirts": 91, "dresses": 18, "bracelets": 96, "rings": 72 },    { "city": "cairn", "trousers": 64, "skirts": 43, "dresses": 14, "bracelets": 95, "rings": 55 },]

页脚

<tfoot class="sticky bg-gray-100 -bottom-1">    <template x-for="row in table.customfooter">        <tr>            <template x-for="col in row">                <td class="px-3 border-b border-gray-200"                    x-init="col.attr && object.keys(col.attr).foreach(e => $el.setattribute(e, col.attr[e]))">                        <div x-html="table.footerdata[col.name)">                        </div>                </td>            </template>        </tr>    </template></tfoot>

customFooter: [    [        { value: 'Total', class: 'font-bold border-r text-center', attr: { rowspan: 2 } },        { name: 'total-trousers', class: 'text-right border-r' },        { name: 'total-skirts', class: 'text-right border-r', },        { name: 'total-dresses', class: 'text-right border-r' },        { name: 'total-bracelets', class: 'text-right border-r' },        { name: 'total-rings', class: 'text-right' },    ],    [        { name: 'total-clothes', class: 'text-center border-r', attr: { colspan: 3 } },        { name: 'total-accessories', class: 'text-center', attr: { colspan: 2 } },    ],],

示例数据：

我们通过包含城市名称和各种服装的示例数据演示了该表的功能。

结论：

此细分展示了 alpine js 如何帮助我们创建具有灵活页眉、正文和页脚的动态表格。这种方式简化了表的创建和管理，特别是对于数据频繁变化的场景。
