我正在尝试按日期对表格进行排序，但它在Chrome和Mozilla浏览器中无效？
<article>

答案 0 :(得分：3)
您需要在Firefox中使用调试器并检查排序比较器功能。检查您的日期值是否为NaN。 （使用isNaN）。
我已经简化并修复了您的代码。
NaN值并设置为明确的内容，例如Infinity。答案 1 :(得分：1)
问题是Date在文本为空时返回NaN（Chrome似乎更灵活），这会导致排序失败。您可以将当前的排序更改为：
new Date($(tr).find('td:eq(2)').text()).getTime() || 0
|| 0确保返回一个数字。最好是拥有辅助功能，这样你就不会重复编码，也不必改变每次出现的事情。
