PHP 用下拉框搜索 MySQL 表

Question

我正在尝试创建一个搜索框来搜索数据库的县字段。如果条件匹配，则记录将显示在表中。我在下拉框中找到了不同的县，但是当我单击记录时，表格没有改变。任何帮助将不胜感激！

如果不刷新页面或使用 javascript 重写页面，您的 PHP 页面将无法更改其中的内容。

我看到您在下拉更改时使用了 MM_jumpMenu() JS 函数。此函数将需要检索数据以供您选择，然后重写表以包含新数据。如果您已经在 J​​S 代码中执行此操作，那么我们需要查看该代码以找出问题所在。

另一种方法是取消 JS 并允许表单将页面提交给它自己。然后在页面顶部读取已从表单传递的选定值，加载数据并相应地写入包。
