【问题描述】：
我创建了一个 HTML 表单，其中包含来自以下项目的下拉列表 postgresql 数据库，我希望表单中的一些字段 当从数据库中选择项目时自动从数据库中填充 下拉菜单。我在表格上还有其他一些字段 用户在按下提交按钮前需要填写 将整个数据推回数据库。
目前我的脚本无法连接到数据库或填充 表单上的下拉列表，也无法自动填充 其他指定的表单字段（它们是项目的属性 在下拉列表中也存储在数据库中）和第二个问题 我还拥有的是，在将数据输入到输入字段后， 点击提交。它在数据库中创建一条新记录，而不是 在数据库中填充所需的列。有人可以请吗 看看我的脚本并帮助我。
这是创建数据输入表单的脚本 下拉菜单

你可以使用ajax技术来实现你想要的。有很多关于它的资源。
