我正在使用 TinyMCE 并希望用西班牙语显示它（es）
TinyMCE 版本信息如下
majorVersion : '3',
minorVersion : '3.9.2',
releaseDate : '2010-09-29'
文档说从这里下载语言包并将文件复制到适当的文件夹：
/tinymce/jscripts/tiny_mce/langs/
/tinymce/jscripts/tiny_mce/themes/advanced/langs/
/tinymce/jscripts/tiny_mce/plugins/<pluginname>/langs/
并且还设置
tinyMCE.init({
// General options
language: 'es',
mode: "textareas",
theme: "advanced",
relative_urls : false,
file_browser_callback : ekmUpload,
plugins: "safari,spellchecker,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,imagemanager,filemanager",
// Theme options
theme_advanced_buttons1: "newdocument,save,print,|,code,preview,fullscreen,|,bold,italic,underline,strikethrough,forecolor,backcolor,|,justifyleft,justifycenter,justifyright,justifyfull,|,formatselect,fontselect,fontsizeselect",
theme_advanced_buttons2: "image,template,|,cut,copy,paste,pastetext,pasteword,|,search,|,bullist,numlist,|,sub,sup,|,undo,redo,|,link,unlink,anchor,|,hr,removeformat,",
theme_advanced_buttons3: "",
theme_advanced_toolbar_location: "top",
theme_advanced_toolbar_align: "left",
theme_advanced_statusbar_location: "bottom",
theme_advanced_resizing: false,
content_css : " ",
editor_selector: "HTMLEditor",
height : '500',
width : '100%',
convert_urls : false,
inline_styles : true,
save_enablewhendirty: true,
save_onsavecallback: "SaveDocuments",
这个答案也给出了同样的建议。
但语言包（zip文件）只包含lang/es.js
这样做后，西班牙语中不会出现任何内容，“格式”、“字体系列”和“字体大小”下拉菜单不会出现在西班牙语中。
我错过了什么？
