##①Without field 
var formData = $("#tbMain table").DataTable().rows('.selected').data();
                //2.截取出  诊疗项目ID(zlxmid)  报告项目ID(bgxmid) 仪器字典编号(yqzdbh)
                var arr=new Array();//这是定义数组来存储 需要的字段
                for(var i=0;i
The output is: 


②With field name
 //1. 获取table表中所有的打钩记录
                var formData = $("#tbMain table").DataTable().rows('.selected').data();
                //2.截取出  诊疗项目ID(zlxmid)  报告项目ID(bgxmid) 仪器字典编号(yqzdbh)
                var arr=new Array();//这是定义数组来存储 需要的字段
                var zlxmmc_id=Number(staData.id);//转出整数
                for(var i=0;i
The output is:
