伙计我的页面最多可以有3个复选框吗?
目前,我有6个复选框..如果我勾选所有6个框...将在顶部显示3个表格,在底部显示3个表格。但是我只想要出现3个最大表格。
因此,我在考虑检查条件 (1)如果仅勾选了1个复选框,则会通知用户必须至少检查2个表才能进行比较.-完成
(2)如果选择了超过3个表。它将通知用户它无法继续并且不会带任何表.-需要帮助

在输入复选框中添加一个类(例如.foo)。
然后你可以做
$('.foo').click(function()
{
//every time a checkbox is clicked you can run your sum checks.
//you can loop over all '.foo' classes and check how many were checked.
//then run an if statement to more dirty work.
});
