如何从displaytag中的struts2复选框获取复选框值到action类 [英] How can i get checkbox values from struts2 checkbox in displaytag to action class

问题描述

我正在使用 struts2 应用程序，我正在使用 displaytag 进行分页支持。

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

现在我我想要一个表格中每一行的复选框。

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" />

直到这里工作正常。现在我想删除通过复选框检查的所有国家。

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

我想要检查的国家/地区的ID。因为我必须采取数组中的值。

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

如果你将一个String []添加到与你的复选框相同的动作中，并通过访问器（getters / setters）公开它，struts 2应自动填充它。

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.
