            document.all.WebOffice1.OptionFlag |= 128;
            //document.all.WebOffice1.HideMenuArea("","","","");
            //init();
            var path=$("#filePath").val();
            var type=$("#fileType").val();
            //alert(type+"====="+path);
            //document.all.WebOffice1.LoadOriginalFile(path,type);
            //document.all.WebOffice1.LoadOriginalFile("D://1.xlsx","xlsx");

            //document.all.WebOffice1.LoadOriginalFile("D://test.doc","doc");
            //document.all.WebOffice1.Open("D://1.xls");
            //document.all.WebOffice1.Open("D://test.doc");
        }

问题已经解决！把地址换成IO流的方式就解决了！
