在script中获取页面结果集表格中的数据

var main=mygrid.gettable("11");  //表示获取非固定列的表格    var main1=mygrid.gettable("01");//表示获取固定列的表格     ///var quantity= mygridgetcolnumber(0,"quantity");    //var per_quantity= mygridgetcolnumber(0,"per_quantity");    var planquantity= mygridgetcolnumber(0,"planquantity");var lastcount= mygridgetcolnumber(0,"lastcount");//得到lastcount对应的列数，在第几列上面    alert(lastcount)    ///var goodspack= mygridgetcolnumber(0,"goodspack");   // var contract_code= mygridgetcolnumber(0,"contract_code");    ///var zy_code= mygridgetcolnumber(0,"zy_code");alert(mygrid.gettable("11").rows.length+"===")//获取表格的行数    if(mygrid.gettable("11").rows.length>0){        for(var i=0;i<=mygrid.gettable("11").rows.length-2;i++){   Var planquantity2=main.rows(i).cells(planquantity).childNodes[0].value;//获取input类型的列名为planquantity的各行的值            alert(planquantity2);Var lastcount2=main.rows(i).cells(lastcount).innerText; //获取label类型的列名为lastcount的各行的值//main.rows(i).cells(lastcount).childNodes[0].value;            alert(lastcount2);            if(planquantity2 > lastcount2){                //alert("请输入数量（担）!");                alert("输入数量(担)不能超过剩余量！");                main.rows(i).cells(planquantity).childNodes[0].focus();                return;            }            return;        }    }
