javascript - 使用 List.js 对存储在 ID 上的数据进行排序

问题描述

问题

List.js 没有正确排序我的 HTML 表格上的数字。发生这种情况是因为我在数字位置使用内部 HTML，如果我只输入数字而不是 ID，排序工作正常。

为什么不像你说的那样把数字放在桌子上？

我承认这是最好的解决方案，它提高了性能并且不使用任何 javascript，但是：

我想要的是：

使“数字”按钮正确地对每个内部的数据进行排序：

document.getElementById("mushroom_N").innerHTML = "some_number";

而不是实际的 ID 名称。（在这种情况下，每个“mushroom_N”）

条件：

如果您愿意，我的代码在codepen上。

感谢您的关注！

var options = {
  valueNames: ['name', 'number']
};

var userList = new List('users', options);

function myFunction() {
  document.getElementById("demo0").innerHTML = 10;
  document.getElementById("demo1").innerHTML = 1000;
  document.getElementById("demo2").innerHTML = 1;
  document.getElementById("demo3").innerHTML = 100;
}
.list {
  font-family: sans-serif;
}

td {
  padding: 10px;
  border: solid 1px #eee;
}

input {
  border: solid 1px #ccc;
  border-radius: 5px;
  padding: 7px 14px;
  margin-bottom: 10px
}

input:focus {
  outline: none;
  border-color: #aaa;
}

.sort {
  padding: 8px 30px;
  border-radius: 6px;
  border: none;
  display: inline-block;
  color: #fff;
  text-decoration: none;
  background-color: #f44336;

解决方案

嗯，我做到了！

您只需要创建一个数组并将元素放入另一个数组中。Codepen适合对我感兴趣或遇到同样问题的人。

var mushs = [
  "100", // Mario
  "10", // Luigi
  "1000", // Peach
  "1" // Toad

  // A change in the values will affect all places at the same time.

];

var options = {
  valueNames: ['name', 'mushrooms'],
  item: '<tr><td class="mdl-data-table__cell--non-numeric name"></td><td class="mushrooms"></td></tr>'
};

var values = [{
    name: 'Mario',
    mushrooms: mushs[0]
  },
  {
    name: 'Luigi',
    mushrooms: mushs[1]
  },
  {
    name: 'Peach',
    mushrooms: mushs[2]
  },
  {
    name: 'Toad',
    mushrooms: mushs[3]
  }
];

var userList = new List('users', options, values);

document.getElementById("mushroom_0").innerHTML = mushs[0];
document.getElementById("mushroom_1").innerHTML = mushs[1];
document.getElementById("mushroom_2").innerHTML = mushs[2];
document.getElementById("mushroom_3").innerHTML = mushs[3];
body {
  margin: 0;
  padding: 20px;
}

input {
  border: solid 1px #ccc;
  border-radius: 5px;
  padding: 7px 14px;
  margin-bottom: 10px
}

input:focus {
  outline: none;
  border-color: #aaa;
}
<div id="users">

  <input class="search" placeholder="Search">

  <table class="mdl-data-table mdl-js-data-table">
    <div id="mdl-table">
      <thead>
        <tr>
          <th class="mdl-data-table__cell--non-numeric">
            <button class="mdl-button mdl-js-button mdl-button--icon sort" data-sort="name">
              <i class="mdl-color-text--red-500 material-icons">sort_by_alpha</i>
            </button>
          </th>
          <th>
            <button class="mdl-button mdl-js-button mdl-button--icon sort" data-sort="mushrooms">
              <i class="mdl-color-text--red-500 material-icons">swap_vertical_circle</i>
            </button>
          </th>
        </tr>
      </thead>

      <tbody class="list"></tbody>

    </div>
  </table>
</div>

<p></p>

<div>Hey, I know that Mario got <span id="mushroom_0"></span> mushrooms, also, Luigi got <span id="mushroom_1"></span> of them, Peach was greed and got at least <span id="mushroom_2"></span> mushs, and Toad got only <span id="mushroom_3"></span>, himself.</div>
