我有一个由其他人构建的网络工具。应用程序根据最终用户输入的搜索参数（例如“零件编号、零件状态等”）查询数据库。当用户点击搜索页面时，他们会看到一个简单的文本框以输入零件编号，以及一个使用 JavaScript 切换显示所有参数功能的按钮。如果用户使用一堆参数进行搜索，则会显示零件列表。如果用户单击零件，他们将被带到零件描述页面。
困境：当用户点击部件描述页面然后调用返回按钮时，他们会看到第一个初始搜索页面，而不是返回到部件列表。我希望将它们带回零件列表，而不是重置表格。
请参阅下面的代码示例（任何帮助将不胜感激）：

<strong>Wildcards</strong><br />
The percent sign '%' allows for the substitution of any number characters (0, 1 or more).<br />
The underscore '_' allows for the substitution of exactly 1 character. It is cumulative so you can use '__' to substitute 2 characters for example.
