我想在我的表格中添加双向箭头(上下),就像tablesorter插件所做的那样。
这是我的fiddle。由于某种原因,在jsfiddle中甚至没有一个箭头显示出来,但它在我的原始表格中运行正常。
我尝试了这个:
$("table th").addClass("headerSortUp");
$("table th").addClass("headerSortDown");
但是它没有起作用。你有什么办法可以做到这一点吗?

最佳解决方案无需图片,纯 CSS。 只需在td
或th
行上放置 headerSortDown
和 headerSortUp
的classname,就会出现小箭头。
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>

<td>Tom</td>
<td>Tom Doe</td>
</tr>

同时检查我的JSFiddle:http://jsfiddle.net/rTXXz/ ,其中提供可工作的示例。
更新:已修复适用于Chrome
我在Chrome中遇到了“无效的属性值”错误。
使用引号可以解决问题:
background: url("data:image/gif;base64, R0lGODlhFQAJAIAAACMtMP///yH5BAEAAAEALAAAAAAVAAkAAAIXjI+AywnaYnhUMoqt3gZXPmVg94yJVQAAOw=") no-repeat 99%;
使用Unicode字符的不同方法
从未排序的表开始,使用默认插入符号
<th>Table Column ▶</th>
在排序后,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) + " ▼")
这里有一个小问题 - 一旦设置了插入符号(caret),在对另一列进行排序时,不会重置之前列上的插入符号。不确定是否是问题,但如果它成为问题,我需要一个功能来重置其他列标题上的插入符号。
这是我的JSFiddle示例
background: url(http://tablesorter.com/themes/blue/bg.gif) no-repeat 99%;
这是一个内联的降序箭头。不幸的是,我不知道如何使数据更小,但生成的图像大小是相同的。
background: url('data:image/gif;base64,R0lGODlhFQAEAPcAAAAAACMtMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAAVAAQAAAgaAP8JHCgwgMGDAQgqXIgw4cKHAw9CnFhwYkAAOw==') no-repeat 99%;
th
元素的data-sort-dir
属性应用样式。
data-sort-dir
属性可以具有asc
或desc
的值,并且通过JavaScript在用户单击标题时添加和删除。
$('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))
}

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(只需微调即可,并且我没有优化div或css中的逻辑 ~ 更像是概念性证明(快速原型))。此方法的另一个好处是,您可以轻松使用类更改箭头的颜色,如果将两个箭头放置在单独的div中,则甚至可以在已选择一个箭头时隐藏一个箭头(当前它们仅在悬停时分别更改颜色)。
