我们有一个系统,对不同大小的页面使用多个装饰器,同时使用相同的内容页面。我正试图设置一个变量,可以传送到内容页面(以 JSP 书写的),例如:
<c:set var="pagetype" value="mobile/" />
此方法不起作用, 因为内容页面被发送到设计器, 因此需要先生成。 是否有一种方法可以将变量在编译之前传送到页面, 这样我就可以使用不同设计器的不同文件夹中的响应图像( 例如 : ) 。
<img src="uploads/${pagetype}/img.jpg />
解决办法是将其添加到请求范围:
<c:set var="pagetype" value="mobile/" scope="request" />
