[转]Struts 中 Multibox 的用法

J2EE学习笔记 — Tue, 11 Mar 2008 14:50:00 GMT

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.action.ActionForm;
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>
