javascript - 动态更改交替行颜色

Question

我有 5 个 tr，这些是行替代颜色。现在如何在删除某些行时动态更改 tr 颜色。

假设下面是表 tr 和 td

这是我的行

tr class='odd'  
tr class='even'
tr class='odd'
tr class='even'
tr class='odd'
tr class='even'
tr class='odd'


tr class='odd'
tr class='even' if I delete this tr, than 
tr class='odd'
tr class='even'
tr class='odd'
tr class='even'
tr class='odd'


tr class='odd'
tr class='even'  class changed  odd to even
tr class='odd'   class changed  even to odd
tr class='even'  class changed  odd to even
tr class='odd'   class changed  even to odd
tr class='even'  
tr class='odd'

你可以这样做:

$('table tr:even td').css("background-color":"");
$('table tr:odd td').css("background-color":"");
