我的数据库名为“ ecc ”。
数据库' ecc '包含表' 客户端 '和表' 任务
表' ecc '包含' ProjectManager '' CompanyName <等字段/ em> '' CompanyStreetAddress '' ZipCode '' CompanyPhone
表' 任务 '包含“ 已分配到 ”，“ 主题”等字段 '，' 日期 '
正确使用日期的数据类型。
在下面的代码中，选择列表的内容是从表' 客户端 ProjectManager '中提取的>”。
所选内容的选择列表存储在“ 已分配到 ”字段中，以及字段“ 主题 <的相应主题/ strong>'和字段日期' 日期 '被用户插入到表' 任务 '中。< / p>
我的问题：每当用户选择从字段' ProjectManager 的表'*** client * '中提取的选择列表的内容时>'其各自的字段' CompanyName '' CompanyStreetAddress '' ZipCode '' CompanyPhone '应显示在**文本区域下。**** 如果有人改写它会感激不尽 谢谢 <html>
