如何从 displaytag 中的 struts2 复选框获取复选框值到操作类

问题描述

我正在开发 struts2 应用程序，我在其中使用 displaytag 来支持分页.

I am working on struts2 application in which i am using displaytag for pagination support.

现在我想为表格中的每一行设置一个复选框，因为我正在这样做.

Now i want a check box for each row in the table for that i am doing this.

<display:table name="countryList" export="true" class="table" id="countryList" pagesize="${selectedPageSize}" decorator="org.displaytag.decorator.TotalTableDecorator" >        
    <display:column property="id"  title="ID" paramId="id" />
    <display:column property="name" title="Name"  sortable="true"/>
    <display:column title="Delete All">
        <s:checkbox  id="check" name="check" fieldValue="%{#attr.countryList.id}" theme="simple"/>
    </display:column>
</display:table>  

<s:submit action="deleteall"  value="DeleteSelected" />

直到这里它的工作正常.现在我想删除通过复选框选中的所有国家/地区.

till here its work fine. now i want to delete all the countries that are checked through the check box.

为此，我想要检查的国家/地区的 ID.为此，我必须采用数组中的值.

for that i want the ids of the countries that are checked .for that i have to take the values in an array.

问题是我如何从 jsp 发送值，然后在动作类中获取它

The problem is how can i send the values from jsp and then get it at the action class
