<form name=mainFrm action="" method="post">
    <input type=text name="desc" id="desc" value="大家好" />
</form>
<script>
   var url = "/pub/doc/prints.jsp";   //子页面的URL
   var popscript = "dialogWidth:1024px;dialogHeight:768px;center:yes;status:no;scrollbars:no";
   var prints = window.showModalDialog(url, window, popscript);
 
   function pmShow(){
      alert("shihuan!");
   }

   function pmShow(arg){
      alert(arg);

   }

</script>
 
//子页面:
<script>
    var argsDoc = window.dialogArguments.document;
    alert(argsDoc.getElementById('desc').value);
    dialogArguments.pmShow();  //调用父页面的JavaScript方法
    dialogArguments.pmShow("haha");  //调用父页面的JavaScript方法,并传参

    //parent.window.dialogArguments.pmShow();

    //window.dialogArguments.parent.pmShow();
