我正在尝试像tablesorter插件一样在我的表中添加双箭头(向上和向下)。

这是我的小提琴。出于某种原因,jsfiddle 中甚至没有一个箭头出现,但它适用于我的原始表格。

我试过这个:

$("table th").addClass("headerSortUp");
$("table th").addClass("headerSortDown");

但它没有用。知道我该怎么做吗?

没有图像的最佳解决方案,纯 CSS。只需将类名headerSortDownheaderSortUp放在tdorth行上,插入符号就会出现。

table td,
table th {
  border: 1px solid silver;
}

.headerSortDown:after,
.headerSortUp:after {
  content: ' ';
  position: relative;
  left: 2px;
  border: 8px solid transparent;
}

.headerSortDown:after {
  top: 10px;
  border-top-color: silver;
}

.headerSortUp:after {
  bottom: 15px;
  border-bottom-color: silver;
}

.headerSortDown,
.headerSortUp {
  padding-right: 10px;
}
<table>
  <thead>
    <tr>
      <th class="headerSortDown">ID</th>
      <th class="headerSortUp">Username</th>
      <th>Fullname</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td>John</td>
      <td>John Doe</td>
    </tr>
    <tr>
      <td>2</td>
      <td>Jenny</td>
      <td>Jenny Smith</td>
    </tr>
    <tr>
      <td>3</td>
      <td>Tom</td>
      <td>Tom Doe</td>
    </tr>
  </tbody>
</table>

另请查看我的 JSFiddle:http: //jsfiddle.net/rTXXz/以获取工作示例。

我进入invalid property value铬。

使用引号它可以工作:

background: url("data:image/gif;base64, R0lGODlhFQAJAIAAACMtMP///yH5BAEAAAEALAAAAAAVAAkAAAIXjI+AywnaYnhUMoqt3gZXPmVg94yJVQAAOw=") no-repeat 99%;

我也将双箭头转换为base64。

问题在于你的.headerSortUp背景。我已将其更改为:

background: url(http://tablesorter.com/themes/blue/bg.gif) no-repeat 99%;

这是一个内联的下降箭头。不幸的是,我不知道如何使数据更小,但生成的图像大小相同。

background: url('data:image/gif;base64,R0lGODlhFQAEAPcAAAAAACMtMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAAVAAQAAAgaAP8JHCgwgMGDAQgqXIgw4cKHAw9CnFhwYkAAOw==') no-repeat 99%;

以下示例基于data-sort-dir添加到th元素的属性应用样式。

data-sort-dir属性的值可以是ascordesc并且当用户单击标题时通过 javascript 添加和删除。

$('table.table-sortable th').on('click', function(e) {
  sortTableByColumn(this)
})

function sortTableByColumn(tableHeader) {
  // extract all the relevant details
  let table = tableHeader.closest('table')
  let index = tableHeader.cellIndex
  let sortType = tableHeader.dataset.sortType
  let sortDirection = tableHeader.dataset.sortDir || 'asc' // default sort to ascending

  // sort the table rows
  let items = Array.prototype.slice.call(table.rows);
  let sortFunction = getSortFunction(sortType, index, sortDirection)
  let sorted = items.sort(sortFunction)

  // remove and re-add rows to table
  for (let row of sorted) {
    let parent = row.parentNode
    let detatchedItem = parent.removeChild(row)
    parent.appendChild(row)
  }

  // reset heading values and styles
  for (let header of tableHeader.parentNode.children) {
    header.classList.remove('currently-sorted')
    delete header.dataset.sortDir
  }

  // update this headers's values and styles
  tableHeader.dataset.sortDir = sortDirection == 'asc' ? 'desc' : 'asc'
  tableHeader.classList.add('currently-sorted')
}

function getSortFunction(sortType, index, sortDirection) {
  let dir = sortDirection == 'asc' ? -1 : 1
  switch (sortType) {
    case 'text': return stringRowComparer(index, dir);
    case 'numeric': return numericRowComparer(index, dir);
    default: return stringRowComparer(index, dir);
  }
}

// asc = alphanumeric order - eg 0->9->a->z
// desc = reverse alphanumeric order - eg z->a->9->0
function stringRowComparer(index, direction) {
  return (a, b) => -1 * direction * a.children[index].textContent.localeCompare(b.children[index].textContent)
}

// asc = higest to lowest - eg 999->0
// desc = lowest to highest - eg 0->999
function numericRowComparer(index, direction) {
  return (a, b) => direction * (Number(a.children[index].textContent) - Number(b.children[index].textContent))
}
table.table-sortable th.currently-sorted[data-sort-dir="asc"]::after {
    content: "\25b2";
}

table.table-sortable th.currently-sorted[data-sort-dir="desc"]::after {

使用 unicode 字符的不同方法

从未排序表的默认插入符号开始

<th>Table Column ▶&lt;/th>

在排序时,根据排序顺序和使用 Jquery 我这样做

$(this).text($(this).text().slice(0,-2) + " ▲&quot;)

或者

$(this).text($(this).text().slice(0,-2) + " ▼&quot;)

但是有一件事 - 一旦设置了插入符号,对另一列进行排序不会重置前一列的插入符号。不确定这是一个问题,但如果它确实成为一个问题,我需要一个函数来重置其他列标题的插入符号。

这是我的 JSFiddle

我能够使用另一个背景图像而不是您使用的图像来使其工作。也许这可以让您对问题有所了解:

.headerSortUp {
  background: url(http://placehold.it/25x25) no-repeat 99%;
}
.headerSortDown {
  background: url(http://placehold.it/25x25) no-repeat 99%;
}

如果您使用的是引导程序:

th, td {
    border: 1px solid black;
    text-align: center !important;
    font-size: 0.8rem !important;
  }

  td:hover, th:hover {
    -webkit-box-shadow: 0 0 5px -1px rgba(115, 127, 255, 1);
    -moz-box-shadow: 0 0 5px -1px rgba(115, 127, 255, 1);
    box-shadow: 0 0 5px -1px rgba(115, 127, 255, 1);
    border: 1px solid rgba(115, 127, 255, 1) !important;
  }

  th i{
     cursor: pointer !important;
  }

  th i:hover{

注意:我添加这个答案是因为它提供了一种在不使用图像的情况下添加箭头的替代方法,但确实遵循将箭头保留在背景中的逻辑。

一种在没有图像的情况下添加箭头的方法,同时保持图像的样式(只需调整它的味道,我没有优化 div 或 css 中的逻辑〜更多的概念证明(快速原型)) . 这种方法的另一个好处是,您可以轻松地使用类更改箭头颜色,而且如果将两个箭头放在单独的 div 中,您甚至可以在已经选择时隐藏一个(目前它们只是在悬停时单独更改颜色)。

看例子
