例如,我有一个代码:
<table>
<tr>
<th>name</td>
<th>price</td>
</tr>
<tr>
<td>a</td>
<td class="sort">5</td>
</tr>
<tr>
<td>b</td>
<td class="sort">3</td>
</tr>
<tr>
<td>c</td>
<td class="sort">8</td>
</tr>
<tr>
<td>c</td>
<td class="sort"></td>
</tr>
<tr>
<td>h</td>
<td class="sort">2</td>
</tr>
<tr>
<td>p</td>
<td class="sort">6</td>
</tr>
<tr>
<td>b</td>
<td class="sort">20</td>
</tr>
<tr>
<td>b</td>
<td class="sort"></td>
</tr>
</table>
我希望这样排序:
<table>
<tr>
<th>name</td>
<th>price</td>
</tr>
<tr>
<td>h</td>
<td class="sort">2</td>
</tr>
<tr>
<td>b</td>
<td class="sort">3</td>
</tr>
<tr>
<td>a</td>
<td class="sort">5</td>
</tr>
<tr>
<td>p</td>
<td class="sort">6</td>
</tr>
<tr>
<td>c</td>
<td class="sort">8</td>
</tr>
<tr>
<td>b</td>
<td class="sort">20</td>
</tr>
<tr>
<td>c</td>
<td class="sort"></td>
</tr>
<tr>
<td>b</td>
<td class="sort"></td>
</tr>
</table>
我使用了这段代码:
function sortNum(a, b) {
return 1 * $(a).find('.sort').text() < 1 * $(b).find('.price').text() ? 0 : 1;
}
function sortTheTable(){
$(function() {
var elems = $.makeArray($('tr:has(.price)').remove())
elems.sort(sortNum)
$('table#information').append($(elems));
});
}
这可行,但问题是,输出是这样的:
<table>
<tr>
<th>name</td>
<th>price</td>
</tr>
<tr>
<td>c</td>
<td class="sort"></td>
</tr>
<tr>
<td>b</td>
<td class="sort"></td>
</tr>
<tr>
<td>h</td>
<td class="sort">2</td>
</tr>
<tr>
<td>b</td>
<td class="sort">3</td>
</tr>
<tr>
<td>a</td>
<td class="sort">5</td>
</tr>
<tr>
<td>p</td>
<td class="sort">6</td>
</tr>
<tr>
<td>c</td>
<td class="sort">8</td>
</tr>
<tr>
<td>b</td>
<td class="sort">20</td>
</tr>
</table>
空的到顶部。我想要底部的空的。
谢谢
