用过FckEditor的朋友都知道，它的选择图片对话框中“浏览服务器”按钮。点击该按钮可以浏览以前已经上传过的文件。不过这个按钮点击后弹出的对话框在MAXTHON浏览器下是以标签形式打开的，这样模态对话框就始终显示在了浏览文件窗口之前，要想选择文件得先关掉模态对话框。先前有朋友提出把弹出模态对话框的功能改为ShowModlessDialog，这个终究不是解决之道，现将我的解决方法写下来与大家分享：

思路就是基于IE内核的浏览器采用模态对话框弹出浏览服务器窗口，其他的仍然window.open不变

修改\fckeditor\editor\dialog\common\fck_dialog_common.js

function OpenFile( fileUrl )
{
    if( window.dialogArguments)
    {
        window.dialogArguments.SetUrl( fileUrl ) ;
        window.close() ;
        window.dialogArguments.focus() ;
    }
    else
    {    
        window.top.opener.SetUrl( fileUrl ) ;
        window.top.close() ;
        window.top.opener.focus() ;    
    }
}

这样就没有问题了。
