修改fckeditor的文件上传功能步骤

2018-10-12 13:50 996 查看

1、要点击链接，然后点击里面的上传tab,不熟悉的人可能找不到这个上传功能
2、插入的就是1个链接，我希望插入链接的同时插入1个图片代表文件类型
效果图:

修改fckconfig.js
1. 在FCKConfig.ToolbarSets["Default"] = 中加入'FuJian',位置自己选
2. 最后加上2句
// 附件上传地址
FCKConfig.FuJianUrl = "/FckEdit/upload.jsp";
// 上传的文件类型
FCKConfig.FuJianAllowedExtensions = ".(doc|xls|ppt|pdf|rar|zip)$";
3. 在对应的语言包中加上：
FuJian : "附件"
4. 修改JS/fckeditorcode_gecko.js 和JS/fckeditorcode_ie.js
注：这2个文件是被压缩过的，在netbeans中点击格式化代码就会解压缩。
5. 在文件中找到：case 'Image':B=new FCKDialogCommand('Image',FCKLang.DlgImgTitle,'dialog/fck_image.html',450,390);
在这句前面加上：
case 'FuJian':B=new FCKDialogCommand('FuJian',FCKLang.FuJian,'dialog/fck_fujian.html',450,200);break;
(这句表示点击"附件"按钮的时候要弹出dialog/fck_fujian.html页面，450,200分别是宽，高)。
再找
case 'Image':B=new FCKToolbarButton('Image',FCKLang.InsertImageLbl,FCKLang.InsertImage,null,false,true,37);
在前面加上：
case 'FuJian':B=new FCKToolbarButton('FuJian',FCKLang.FuJian,null,null,false,true,77);break;
77是附件在工具栏上要显示的图标的索引，
图标文件在:editor/skins/default/fck_strip.gif 文件，图标都是16×16的.
到这里按钮已经能显示出来了，下面是fck_image.html的代码:
