Jquery easyui : 实现前端数据包格式化输出，支持多种模块式定义，只需要添加相应的预设参数即可实现丰富的前端。
资料参考： http://www.jeasyui.com/
Jquery sparkline: 基于jQuery 的js插件，底层调用html5的canvas标签，并通过js动态实现在数据表行内画条形图或趋势图，操作简单，可实现不同类型的图形化，如线形图，饼状图，柱形图。
资料参考：http://omnipotent.net/jquery.sparkline/#s-docs
注意：sparkline依赖于jQuery1.4.3或以上的版本
jqplot: 也是基于jQuery 的js插件，可以实现基于数据画趋势图，主要是线形图为主。
资料参考: http://www.jqplot.com/tests/
1） 要使用以上插件的先行条件是要预先加载在html里。
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<link rel="stylesheet" type="text/css" href="//img.6waves.com/jquery-easyui/themes/gray/easyui.css">

<script type="text/javascript" src="js/jquery.sparkline.min.js"></script>
<script type="text/javascript" src="js/common.js"></script>
</head>
2）在表格里调用jquery easyui的datagrid插件
<th data-options="field:'trend',width:80,title:'Trend',formatter:formatTrend" align="right"></th>
通过formatTrend函数实现循环把数据表指定列格式化，格式化后的内容在往后的js中调用，formatTrend函数定义如下：
function formatTrend (value,row,index) {
var rs='';
rs = '<div id=\'sparkline-jqplot-'+row.game_id +'\'><a href=\'#\' onclick=\'startGraph(this.parentNode.id,'+row.game_id+',6)\' alt=\'cost trend\' title=\'Click for more records\'> <span class=sparkline-cost-trend id=sparkline-'+row.game_id+'></span></a></div>';
return rs;
}
以上生成的列添加了一个onclick事件，点击后发送请求，然后根据返回数据生成jqplot线性图。
生成的html格式如图一
3）调用sparkline插件实现在页面加载完后发送ajax请求，获取数据后循环实现Trend这列的线形图的生成。
function loadSparkline(){
$.getJSON('cost_category_json.php?all&limit=6',function(data){
$.each(data,function(i,value){
$("#sparkline-"+i).sparkline(value,{type: 'bar', barColor: 'green',colorMap: { '0': '#f00' }} );
//alert(value);
})
})
}
发送请求后获取到的数据格式为：

}startGraph函数发送的请求获取到得数据格式为：
