Question

有一个Web应用程序可从不同站点收集数据。主页上的表单以两个字段的形式显示，您可以在其中几种语言和城市中进行选择。当您按下搜索按钮时，仅显示一对语言和城市的结果，而与表单中选择的变体无关，因为action ='''表单中只有一个URL。如何动态更改表单action =''，具体取决于主页上表单的变体选择。我希望我已经清楚地解释了。谢谢您的帮助！

您使用的是django模板，因此可以使用动态上下文的标签。像这样：

form action="/{{ your_path}}" method="post" class="mt-5 mb-5 text-center">

可变形式action =“ /”
