js代码：

Html代码

var main_list_size = $(".main_list_size").val();//获取主单循环大小

main_list_size = parseInt(main_list_size);

var count_concern = parseInt(0);

var count_noConcern = parseInt(0);

var count_validateNumber = parseInt(0);

if(main_list_size<=0){

$(".count_main").hide();//没有数据时，隐藏该行

}else{

var concern = $(".concern noConcern validateNumber");

for(var i=0;i<main_list_size;i++){

count_concerncount_concern = count_concern+ parseInt($(".concern").eq(i).html());

count_noConcerncount_noConcern = count_noConcern + parseInt($(".noConcern").eq(i).html());

count_validateNumbercount_validateNumber = count_validateNumber + parseInt($(".validateNumber").eq(i).html());

}

$(".count_concern").html(count_concern);

$(".count_noConcern").html(count_noConcern);

$(".count_validateNumber").html(count_validateNumber);

$(".count_main").show();//有数据时，显示该行

}

这样，下面的统计信息就全出来了
