感谢大家帮忙了！！！

用window.open打开son.jsp然后在son.jsp中
window.opener.document.getElementById('returnValue').value='the value...';

解决方案 »

  1.   

    function return() 
        { 
            dialogArguments.document.getElementById("returnValue").value="asdasdasdasdasd"; 
            //var strReturn; 
            //strReturn=document.getElementById("paraFiles").value; 
           // window.returnValue =strReturn; 
            window.close(); 
        }
