js前台调用excel,直接读取excel 内容（要安装office整套软件）

var filePath1 = document.getElementById('upfile');

  //创建操作EXCEL应用程序的实例 

        var oXL = new ActiveXObject("Excel.application"); 

        //打开指定路径的excel文件 

        var oWB = oXL.Workbooks.open(filePath1.value); 

        //操作第一个sheet(从一开始，而非零) 

        oWB.worksheets(1).select(); 

        var oSheet = oWB.ActiveSheet; 

        //使用的行数 

        var rows =  oSheet .usedrange.rows.count; 

        var trHtml="";

//        try { 

            for (var i = 2; i <= rows; i++) {

            var cll1 = oSheet.Cells(i, 1).value;

            var cll2 = oSheet.Cells(i, 2).value;

            var cll3 = oSheet.Cells(i, 3).value;

            var cll4 = oSheet.Cells(i, 4).value;

            var cll5 = oSheet.Cells(i, 5).value;

            var cll6 = oSheet.Cells(i, 6).value;

            var cll7 = oSheet.Cells(i, 7).value;

//            alert(cll1+"-"+cll2+"-"+cll3+"-"+cll4+"-"+cll5+"-"+cll6+"-"+cll7);

            var currentRow = wms_ow_container_dw_info.insertRow();

            wms_ow_container_dw_info.setElement(currentRow, "customerNo", cll1);

            wms_ow_container_dw_info.setElement(currentRow, "blNo", cll2);

            wms_ow_container_dw_info.setElement(currentRow, "qty", cll3);

            wms_ow_container_dw_info.setElement(currentRow, "weight", cll4);

            wms_ow_container_dw_info.setElement(currentRow, "volume", cll5);

            wms_ow_container_dw_info.setElement(currentRow, "palletQty", cll6);

            wms_ow_container_dw_info.setElement(currentRow, "remarks", cll7);

            }

//          } catch(e) {

        oXL.Application.Quit(); 

          //手动调用垃圾收集器
