datatables组件加载数据

使用jquery的datatables插件渲染表格组件时，最佳的方法如下：

*  全局定义dataTables对象变量；
 *  页面加载时初始化dataTables对象；
 *  查询时，使用dataTables对象的api加载数据；

示例：

<%@ page language="java"  pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    
    <head>
    	<meta charset="UTF-8">
    	<%@ include file="common.jsp" %>
    	<script type="text/javascript" src="<%=basePath %>js/datatables.min.js"></script>
    	<link rel="stylesheet" type="text/css" href="<%=basePath %>css/datatables.min.css" />
    </head>
    
    <body>
    	<div class="text-c" style="padding:9px;height:auto;" align="left">
    		<button name="" id="" class="btn btn-success" type="submit" onclick="gridSearch();">查询</button>
    	</div>
    
    	<div style="width:98%" id="tb1">
    		<table id="dataTableTest" class="table table-border table-bordered table-bg table-hover table-striped table-responsive">
    			<thead>
    				<tr class="text-c">
    					<th>
    						<div style="width:75px">测试1</div>
    					</th>
    					<th>
    						<div style="width:75px">测试2</div>
    					</th>
    					<th>
    						<div style="width:75px">测试3</div>
    					</th>
    				</tr>
    			</thead>
    		</table>
    	</div>
    	<br />
    
    	<div style="width:98%" id="tb2">
    		<table id="dataTableTest1" class="table table-border table-bordered table-bg  table-sort table-responsive">
    			<thead>
    				<tr class="text-c">
    					<th>
    						<div style="width:75px">a1</div>
    					</th>
    					<th>
    						<div style="width:75px">a2</div>
    					</th>
    					<th>
    						<div style="width:75px">a3</div>
    					</th>
    				</tr>
    			</thead>
    			<tbody></tbody>
    		</table>
    	</div>
    	<br>
    	<br>
    
    </body>
    <script>
    	
    
    	var dataTable,dataTable1;
    	$(function () {
    		//初始化dataTables对象
    		dataTable = $("#dataTableTest").DataTable({
    			bFilter: false, //是否启动过滤、搜索功能 
    			bLengthChange: false,//是否显示一个每页长度的选择条（需要分页器支持）
    			bSort: false,//是否启动各个字段的排序功能  
    			bPaginate: false,//是否显示（应用）分页器  
    			bInfo: false,//是否显示页脚信息，DataTables插件左下角显示记录数  
    			stripeClasses: ["table-striped", "even"],// 为奇偶行加上样式，兼容不支持CSS伪类的场合
    			destroy: true,//解决Cannot reinitialise DataTable
    			columns: [

上面演示了两个dataTables的数据加载，一个是不分页，一个是分页。
