两种形式 [英] Two forms
问题描述
我在一个页面上有两个表单。在表格A中，我有下拉列表（单个
选择）。当我单击表单B中的提交按钮时，我想获取表单A下拉列表中显示的值
。可以这样做吗？
将两个表单分开的原因是表单A打开一个新的浏览器
窗口，并选择该表单，而表单B将它保存在同一个
浏览器中它的选择窗口。但是，下拉列表值是
两者都使用，我不想在表格B中重复该列表。

I have two forms on one page. In Form A I have drop-down list (single
selection). When I click a submit button in form B, I would like to pick up
the value showing in the drop down list of Form A. Can this be done?
The reason for separating the two forms is that Form A opens a new browser
window with selection in that form, whereas Form B keeps it in the same
browser window for its selections. The drop-down list value, however, is
used in both and I would not want to repeat that list in Form B.

分离这两个表单的原因是表单A打开一个新的
浏览器窗口，其中包含该表单中的选择，而表单B将其保存在相同的浏览器窗口中以供选择。但是，下拉列表值在两者中都使用了，我不想在表单B中重复该列表。

< ？php
if（isset（
I don''t know AJAX.
[ php code]
<?php
if (isset(
_POST [''A'']））{
_POST[''A''])) {
