我如何通过变量从一个表单到javascript弹出式表单
How do I pass variable from a form to javascript popup form?
我有一个表单的按钮，打开一个javascript/css弹出窗口。在弹出窗口上，我有一个文本区，将用于向数据库字段添加评论。问题是，我需要传递它的值从主页(一个调用弹出窗口)，这将确定哪个条目在数据库中更新。但我一直在努力让它工作。这是我的代码。我需要有变量发送到update.php页面。请帮助。

你正在使用一个JS/CSS弹出，所以只是传递$row['job']在你的popup_show()调用(假设你能够修改或重载JS函数)，然后填充它在你的弹出HTML与Javascript的隐藏字段。按照您现在的做法，您必须为结果集中的每一行复制一次Popup HTML块，才能使其工作。
