        doc.action = "Noname4.html";
        doc.submit();
        previewWindow.focus();
      }function doProperty(){
        var doc = document.myForm;
        doc.action = "Property.jsp";
        doc.submit();
    }
    //-->
    </SCRIPT></HEAD>
    <FORM METHOD=POST ACTION="" name ="myForm">
    <input type="button" onclick="doPreview()" value= "preview">
    <input type="button" onclick="doProperty()" value= "link">
    </FORM>
    <BODY>
    </BODY>
    </HTML>
    页面中利用此方法弹出previewWindow窗口后，主页面的link连接窗口也变成了弹出窗口。
    不知道问题出在哪里，请高手指点.
