• struts2 s:optiontransferselect 标签的使用


    在页面中做数据的导出时候使用。

    使用此标签时一定要在页面中加入<s:head/> 原因是此标签和dojo的结合。

    login.jsp

    <%@ taglib uri="/struts-tags" prefix="s" %>

     <head>

         <s:head/> 

      </head>

       <s:form action="loginAction" method="post" name="myForm">

      <s:optiontransferselect label="选择你喜欢图书" 
                  name="cnbook" leftTitle="中文图书"  list="{'struts2权威指南','轻量级javaeye 企业应用空实战','ajax讲义'}"
                  doubleName="enBook"  rightTitle="外文图书" doubleList="{'JavaScrip:The definitive Guide','export one-to-one'}"  multiple="true"
                  addToLeftLabel="向左移动" addToRightLabel="向右移动" addAllToRightLabel="全部右移" addAllToLeftLabel="全部左移"
                   allowSelectAll="true" headerKey="cnKey" headerValue="选择图书" emptyOption="true"   doubleHeaderKey="enKey"
                   doubleHeaderValue="选择外文图书" doubleMultiple="true" doubleEmptyOption="true"  leftDownLabel="向下移动"
           rightDownLabel="向下移动"
           leftUpLabel="向上移动"
           rightUpLabel="向上移动" >
       </s:optiontransferselect>
         <s:submit value="提交"></s:submit>
     </s:form>

    loginAction.java

    public class LoginAction extends ActionSupport {
       
     /**

     private static final long serialVersionUID = 8837849417087243469L;

      String usrname = getText("username"); // 获取
      ActionContext context = ActionContext.getContext(); 
      HttpServletRequest request = (HttpServletRequest) context.get(ServletActionContext.HTTP_REQUEST); 
      
          String [] cnbooks =   request.getParameterValues("cnbook");
          for(int i=0;i<cnbooks.length;i++){

          }
         
          List<Book> lists = new ArrayList<Book>();
          Book book1 = new Book(1,"struts2权威指南",20.2);
          Book book2 = new Book(2,"轻量级javaeye 企业应用空实战",20.2);
          Book book3 = new Book(3,"ajax讲义",20.2);
          lists.add(book1);
          lists.add(book2);
          lists.add(book3);
          request.setAttribute("lists", lists);
      return SUCCESS;
     }

    Book.java

    public class Book {
     private int id;
     private String name;
     private double money;
     public Book() {
     }
     public Book(int id, String name, double money) {
      super();
      this.id = id;
      this.name = name;
      this.money = money;
     }

    }

    success.jsp

    <s:optiontransferselect label="选择你喜欢图书" 
                  name="cnbook" leftTitle="中文图书"  list="#request.lists"  listValue="name" listKey="name"
                  doubleName="enBook"  rightTitle="外文图书" doubleList="{'JavaScrip:The definitive Guide','export one-to-one'}"  multiple="true"
                  addToLeftLabel="向左移动" addToRightLabel="向右移动" addAllToRightLabel="全部右移" addAllToLeftLabel="全部左移"
                   allowSelectAll="true" headerKey="cnKey" headerValue="选择图书" emptyOption="true"   doubleHeaderKey="enKey"
                   doubleHeaderValue="选择外文图书" doubleMultiple="true" doubleEmptyOption="true">
       </s:optiontransferselect>

    第三图是从后台取出的数据,list 中只能存入对象,在页面上再接收!
