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++){
