我的js函数/报告调用函数

function getShipServiceReport(ship_no,to_date, fromDate){ 
     var shipNos=document.getElementById(ship_no).value; 
     var toDate=document.getElementById(to_date).value; 
     var fromDate=document.getElementById(fromDate).value; 
     var fileType=$('input[name="optionsRadios"]:checked').val(); 
     var ajaxURL = "getShipServiceReportRT.do?ship_no="+shipNos+"&to_date="+toDate+"&fileType="+fileType+"&fromDatee="+fromDate;   
     window.open(ajaxURL,'_blank'); 
//$("#documentArea.html('<iframe src='"+ajaxURL+"' frameBorder='0' style='height:1200px;width:100%;'></iframe>')"); 

    }
