在JSP页面中更新组合框而不刷新 [英] updating combobox without refreshing in JSP page

问题描述

嗨！

我必须解决JSP中的一个问题。实际上，我有一个JSP页面说Ex1.jsp.In这个Ex1.jsp我有一个锚标记链接到另一个JSP页面即当我点击链接时，另一个弹出窗口将打开。我的问题是弹出窗口，父窗口有相同的组合框。如果我在弹出窗口（Ex2.jsp）中通过html表单添加数据，它进入组合框......但是父窗口（Ex1.jsp）的组合框中的数据只在我刷新父页面（Ex1.jsp）页面时才进入...那么如何在两个组合框中输入数据而不刷新???

我不明白你在这里说的一切，但我怀疑Javascript专家可能会就此问题说几句话，所以我也会在那里复制。

I don''t understand all that you''re saying here, but I suspect a Javascript expert may be able to say a few words on the matter, so I''ll copy this there as well.

你可以通过window.opener（）方法获得父窗口的引用。

一旦你有父窗口引用，你就可以了可以通过简单的javascript向选择框添加选项。

you can have a reference of the parent window by window.opener() method.
Once you have the parent window reference, you can add options to the select box by simple javascript.
