我解决了 原来在2.66版本并不是由FCKeditor自己控制文件的上传大小了
而是交给你语言平台本身 我在ASP.NET 的配置一下就好了

fckeditor限制上传文件大小的方法
2009-11-11 09:50
以前用fckeditor的时候花了好多时间把FCKeditor.Net_2.6.3的代码都搞明白了,自己也改了些,今天重新要用fckeditor时却有好多又生疏了,还是做点记录吧,文字总是比人的记性好,今天把限制上传文件大小的方法拿出来跟大家分享,下次再发布其他的.(不要问我fckeditor是什么哈!)


由于FCKeditor本身是开源的,所以我们可以对里面的某些代码进行修改.

先到fck官方网站下载FCKeditor.Net_2.6.3.

我用的vs2005版的fck.net , 打开FileWorkerBase.cs

很明显protected void FileUpload( string resourceType, string currentFolder, bool isQuickUpload )是用来控制上传文件的方法, 里面有个if ( oFile == null )

{

this.SendFileUploadResponse( 202, isQuickUpload );

return;

},跟踪调试后发现SendFileUploadResponse是向页面发送各种报告的,最后跟踪到了OnUploadCompleted方法

然后在FCKeditor的页面里搜索OnUploadCompleted,结果找到了fckeditor\editor\dialog\fck_image\fck_image.js,

fckeditor\editor\dialog\fck_link\fck_link.js与fckeditor\editor\dialog\fck_flash\fck_flash.js,他们里面各自都有OnUploadCompleted方法,很明显里面定义了各种编码的报告信息,下面是我改的编码:

switch ( errorNumber )

{

case 0 : // No errors

alert( '您的flash已经成功上传!' ) ;

break ;

case 1 : // Custom error

alert( customMsg ) ;

return ;

case 101 : // Custom warning

alert( customMsg ) ;

break ;

case 201 :

alert( '已经存在相同名字的图片. 您上传的flash将被命名为 "' + fileName + '"' ) ;

break ;

case 202 :

alert( '不支持的文件类型!' ) ;

return ;

case 203 :

alert( "安全警告. 您可能没有权限上传flash. 请联系管理员." ) ;

return ;

case 204 :

alert( "上传flash不能超过150k , 请重新制作后上传!" ) ;

return ;

case 500 :

alert( 'The connector is disabled' ) ;

break ;

default :

alert( 'Error on file upload. Error number: ' + errorNumber ) ;

return ;

}

你可以根据自己的需要增加编码,对应的在FCKeditor.Net_2.6.3.里的FileWorkerBase.cs的FileUpload方法里增加判断就可以了.

比如我现在要限制文件上传大小,在FileUpload里增加判断

if (oFile.ContentLength > 1024 * 150)

{

this.SendFileUploadResponse(204, isQuickUpload);

return;

}

204是我自己定义的错误编码,FCKeditor.Net_2.6.3改好了要生成dll然后在放在项目的bin里

最后在项目里相应的FCKeditor文件里找到前面所述的OnUploadCompleted,加上

case 204 :

alert( "上传flash不能超过150k , 请重新制作后上传!" ) ;

return ;

好了,测试通
