在 ActionForm 中定义一个数组 String[] selectedOptions 用于存放复选框被选中的值，
数组 LabelValueBean[] possibleOptions 用于显示所有的复选框的值。
import org.apache.struts.util.LabelValueBean;
.
.
.
public class MyActionForm extends ActionForm
{
private LabelValueBean[] possibleOptions;
private String[] selectedOptions;
public MyActionForm()
{
// Initialise the LabelValueBeans in the possibleOptions array.
LabelValueBean[] lvBeans = new LabelValueBean[4];
lvBeans[0] = new LabelValueBean("Alpha", "A");
lvBeans[1] = new LabelValueBean("Beta", "B");
lvBeans[2] = new LabelValueBean("Charlie", "C");
lvBeans[3] = new LabelValueBean("Delta", "D");
this.possibleOptions = lvBeans;
}
public LabelValueBean[] getPossibleOptions()
{
return possibleOptions;
}
public String[] getSelectedOptions()
{
return selectedOptions;
}
public void setSelectedOptions(String[] selectedOptions)
{
this.selectedOptions = selectedOptions;
}
}
在 JSP 中使用以下代码：
<logic:iterate name="myActionForm" id="item" property="possibleOptions">
<html:multibox property="selectedOptions">
<bean:write name="item" property="value" />
</html:multibox>
<bean:write name="item" property="label" /><br />
</logic:iterate>
