帝国CMS8.0文章内容CKedit代码高亮显示

文末的压缩文件，解压后将文件夹codesnippet上传到：./eadmin/admin/ecmseditor/infoeditor/plugins/（eadmin和admin这两个文件夹的名称如果改过，那就上传到你改后的文件夹内）

将：monokai-sublime.min.css、highlight.min.js、highlightjs-line-numbers.js这三个文件上传到网站目录的合适文件夹（前台需要调用这三个文件，不用放后台管理地址的目录。）

把./eadmin/admin/ecmseditor/infoeditor/config.js改为下面内容：

function EcmsEditorDoCKhtml(htmlstr){
    if(htmlstr.indexOf('"')!=-1){return '';}
    if(htmlstr.indexOf("'")!=-1){return '';}
    if(htmlstr.indexOf("/")!=-1){return '';}
    if(htmlstr.indexOf("\\")!=-1){return '';}
    if(htmlstr.indexOf("[")!=-1){return '';}
    if(htmlstr.indexOf("]")!=-1){return '';}
    if(htmlstr.indexOf(":")!=-1){return '';}
    if(htmlstr.indexOf("%")!=-1){return '';}
    if(htmlstr.indexOf("<")!=-1){return '';}
    if(htmlstr.indexOf(">")!=-1){return '';}
    return htmlstr;
}
 
function EcmsEditorGetCs(){
    var js=document.getElementsByTagName("script");
    for(var i=0;i<js.length;i++)
    {
        if(js[i].src.indexOf("ckeditor.js")>=0)
        {
            var arraytemp=new Array();
            arraytemp=js[i].src.split('?');
            return arraytemp;
        }
    }
}
 
var arraycs=new Array();
arraycs=EcmsEditorGetCs();
arraycs[0]=arraycs[0].replace('infoeditor/ckeditor.js','');
arraycs[1]=document.getElementById('doecmseditor_eaddcs').value;
arraycs[1]=EcmsEditorDoCKhtml(arraycs[1]);
 
CKEDITOR.editorConfig = function( config ) {
 
    config.filebrowserImageUploadUrl = '';
    config.filebrowserFlashUploadUrl = arraycs[0];

编辑现用的新闻内容模板，合适位置加入：

<!--代码高亮引入脚本 -->  
<link rel="stylesheet" href="[!--news.url--]css/monokai-sublime.min.css">
<script src="[!--news.url--]js/highlight.min.js"></script>

浏览器和帝国后台都更新一下缓存就完成安装了。后台编辑时最好还是要去选择一下“代码语言”，防止自动判断有时程序偶尔出错。
