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headerSortDown
和headerSortUp
放在td
或th
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>

答案 1 :(得分:3)
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。
答案 2 :(得分:2)
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asc
或desc
,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 {

答案 8 :(得分:0)
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) + " ▲")
或
$(this).text($(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
