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：
