报表的多行数据求汇总

如下图展示 ：求出总数

?

?

使用jquery强大的选择器来计算

?

?1.. ?jsp代码如下

<table class="data-list">
		            <tr>
						<th class="brl-none">章节</th>
						<th><font color="red">试题数量</font></th>
						<th>新导入</th>
						<th>要录视频</th>
						<th>不录视频</th>
						<th><font color="green">待消重</th>
						<th><font color="red">已有视频</font></th>
						<th>总分的试题</th>
						<th>未总分</th>
						<th>已总分</th>
						<th>未处理</th>
						<th>绑定考察点</th>
						<th>完成任务</th>
		            </tr>

??$(function(){

	
        var tdt = 0;

        // 有多少列，就依次向上增加
        var arr=["b","c","d","e","f","g","h","i","j","k","l","m"];    
	for(i=0; i<arr.length;i++){
		tdt = 0;
		$("span[id^=td_"+arr[i]+"]").each(function(){
		   tdt = tdt + parseInt($(this).text());
		});
		$("#tdt_"+arr[i]).text(tdt);
	}

});
