需要不可数循环dillema的逻辑解决方案(Need logical solution for uncountable loop dillema)

假设我在java中有这种循环（不是一个确切的代码，它既不是真正有效的代码，只是为了给你一个通用的情况视角）：

print "<ul>"; while (res = fetch(database)) { print ("<li>" + res.col['data'] + "</li>"); } print "</ul>";

我有这个CSS，这使得列表中的最后一项具有红色。

ul li:last-child { color: red; }

这适用于大多数浏览器。 问题是：

我也需要在IE8上做这个工作。 IE8不支持last-child。 我无法测试“while”的当前迭代是否进入最后一次迭代。 或者说，我无法检查循环何时结束。 这不是一个普通的循环，但让我们这样说。 所以我不能给最后一个<li>一个班级，比如class="lastchild" 。 我也试过javascript和jquery，两者都不能选择“last-child”，因为它们取决于选择的css，我想。

在这种情况下，最好的方法是怎样的？ 谢谢。

Supposed I have this kind of loop in java (not an exact code, neither it's a truly valid code, but just to give you a general perspective of situation):

print "<ul>"; while (res = fetch(database)) { print ("<li>" + res.col['data'] + "</li>"); } print "</ul>";

and I have this CSS, which makes the last item on the list has red color.

ul li:last-child { color: red; }

this works fine on most browsers. the problems are:

I need to make this work on IE8 too. IE8 doesn't support last-child. I cannot test whether current iteration of "while" is entering last iteration or not. or let's say, there's no way I could check when the loop would end. this is not an ordinary loop, but let's just say like that. so I can't give the last <li> a class, say class="lastchild". I also tried with javascript and jquery, and both can't select "last-child" either, as they depends on the css for the selection, I think.

how is the best approach in this situation? thanks.

最满意答案

print "<ul>"; String liText=null; while (res = fetch(database)) { if (liText!=null) { print ("<li>" + liText + "</li>"); } liText=res.col['data']; } if (liText!=null) { print ("<li style='the last element style'>" + liText + "</li>"); } print "</ul>";

移动最后一行的添加，然后在那里应用所需的样式

print "<ul>"; String liText=null; while (res = fetch(database)) { if (liText!=null) { print ("<li>" + liText + "</li>"); } liText=res.col['data']; } if (liText!=null) { print ("<li style='the last element style'>" + liText + "</li>"); } print "</ul>";

Move the adding of the last line out of the while and apply desired style there
