将排序箭头添加到类似表格分类器

时间:2013-07-14 12:53:18

标签: jquery css

我正在尝试像tablesorter插件那样向我的表添加双箭头(向上和向下)。

这是我的fiddle。出于某种原因,甚至没有一个箭头显示在jsfiddle中,但它可以在我的原始表格上运行。

我试过了:

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

但它没有用。知道怎么做吗?

最佳解决方案没有图片,纯CSS 。只需将类名headerSortDownheaderSortUp放在tdth行,就会显示插入符号。

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>

我在Chrome中获得invalid property value

引用它有效:

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

我也将双箭头转换为base64。

问题在于您的.headerSortUp背景。我用下面的内容改了它:

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

答案 3 :(得分:2)

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

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

答案 4 :(得分:1)

我能够使用其他背景图像而不是您正在使用的图像来使其工作。也许这可以让你对这个问题有所了解:

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

答案 5 :(得分:0)

注意:我正在添加这个答案,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,但确实遵循了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同时保持图像样式的方法(只需要调整它的味道,我没有优化div中的div或逻辑〜更多的概念证明(快速)原型))。这种方法的另一个好处是,您可以轻松地更改箭头着色类加上如果您将两个箭头放在单独的div中,您甚至可以在已经选中时隐藏一个(目前它们只是在悬停时单独更改颜色)。

以下示例基于添加到data-sort-dir元素上的th属性应用样式。

data-sort-dir属性的值可以为ascdesc,并在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字符的另一种方法

从默认插入符开始,显示未排序的表格

<th>Table Column ▶</th>

在排序时,根据排序顺序并使用Jquery,我这样做

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

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

尽管有一件事-设置了插入符后,对另一列进行排序并不会重置前一列的插入符。不确定这是一个问题,但如果确实成为问题,则需要一个函数来重置其他列标题的插入符号。

这是我的 JSFiddle
