如何从 displaytag 中的 struts2 复选框获取复选框值到操作类
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
推荐答案
如果您将 String[] 添加到与您的复选框命名相同的操作中并通过访问器(getter/setter)公开它，struts 2 应该自动填充它.
If you add a String[] to your action named the same as your checkbox(s) and expose it via accessors (getters/setters) struts 2 should auto populate it.
