6.窗口弹出在不同浏览器下的实现
if ($.browser.msie) {
        window.showModalDialog(openUrl, argumentObj, size+"scroll:no;");
    } else {
        var win = window.open(openUrl,"",
            size + "scrollbars=no, dialog=yes, modal=yes, toolbar=no, menubar=no, resizable=no, location=no, status=no");
        win.focus();
    }

7.弹出一个子类窗口，将子类窗口的参数传给父类窗口实现（FF & IE）
if ($.browser.msie) {
        window_value = window.dialogArguments.argumentObj.windowId;
        channel_value = window.dialogArguments.argumentObj.channel;
    } else {
        window_value = window.opener.windowId;
        channel_value = window.opener.channel;
    }

8.超级恶心的IE 居然不支持 css 选择器,还好JQuery 秒秒钟就可以搞定
$("input").each(function(){
                        if($(this).attr("type")=="checkbox" || $(this).attr("type")=="radio"){
                            $(this).addClass("MP");
                        }
                    });
