Simple you could pass the value inside your <a>
like this as query string, 很简单,您可以像这样将<a>
内部的值作为查询字符串传递,
<td><a href = "retrieve_image?Id=${item.getIid()}">${item.getIid()}</a></td>
Get the value from the Id
in your servlet . 从servlet中的Id
获取值。 you will get the value for current iteration inside the for-each
loop as you print ${item.getIid()}
在打印${item.getIid()}
您将在for-each
循环中获得当前迭代的值。
Hope this helps !! 希望这可以帮助 !!
