YUI2.8 实现TabView和DataTable的结合使用

CSS Struts JavaScript Yahoo json

实现的功能：使用YUI2.8 实现TabView和DataTable的结合使用，在TabView添加两个tab，每个tab都是datatable，datatable的数据是从后台动态获取数据，同时实现分页的功能。

简述我的调试过程，先做好一个datatable，保证单个datatable能正确地显示，且分页功能没有问题，然后做一个简单的tabview，也同样保证没有问题之后；再完成最后一步的整合功能。

主要的时间是花在写JS脚本和调试上，做事还是一步一步来，遇到问题不要紧张，仔细想想是自己什么地方写错了，或者那个JS CSS文件没有引对。

我也是YUI的新手，希望有人能和我互相交流。

后台的代码

1、YuiTabAction.java

package com.demo.action;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import org.apache.struts2.ServletActionContext;

import com.demo.model.Book;
import com.demo.model.InstBean;
import com.demo.yuiutil.JSONResult;
import com.demo.yuiutil.YUIPagination;
import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("all")
public class YuiTabAction extends BaseStruts2Action{
	public void getBookList(){
		System.out.println(" getBookList is called....startIndex="+startIndex);
		List<Book> bookList = new ArrayList<Book>();
		recordsReturned = 10;
		for(int i=1; i<10; i++){
			Book book = new Book();
			book.setId(startIndex+i);
			book.setAmount(startIndex+i+10);
			book.setQuantity(startIndex+i+100);
			book.setTitle("title("+startIndex+i+")");
			bookList.add(book);
		}
		pageSize = 10;
		totalRecords = 20;//假设总记录数是20条,
		YUIPagination yuiPage = new YUIPagination();
		yuiPage.setRecordsReturned(recordsReturned);
		yuiPage.setTotalRecords(totalRecords);
		yuiPage.setStartIndex(startIndex);
		yuiPage.setPageSize(pageSize);
		yuiPage.setSort("ASC");
		yuiPage.setRecords(bookList);		
		this.outJson(yuiPage);	
	}
	
	public void getInstList(){
		System.out.println(" getInstList is called....startIndex="+startIndex);
		List<InstBean> bookList = new ArrayList<InstBean>();
		recordsReturned = 10;
		for(int i=1; i<10; i++){
			InstBean bean = new InstBean();
			bean.setPtInsId(startIndex+i);
			bean.setPtInsName("instName"+(startIndex+i+10));
			bean.setPtInsDesc("desc("+startIndex+i+")");
			bookList.add(bean);
		}
		pageSize = 10;
		totalRecords = 20;//假设总记录数是20条,
		YUIPagination yuiPage = new YUIPagination();
		yuiPage.setRecordsReturned(recordsReturned);
		yuiPage.setTotalRecords(totalRecords);
		yuiPage.setStartIndex(startIndex);
		yuiPage.setPageSize(pageSize);
		yuiPage.setSort("ASC");
		yuiPage.setRecords(bookList);		
		this.outJson(yuiPage);	
	}
}

2、struts.xml

        "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>

	<package name="yuitab" namespace="/yuitab" extends="struts-default">

	</package>
</struts>
