织梦DedeCms 5.7代码块高亮的解决方法

2016-09-09 dedecms安装使用 织梦,DedeCms,5.7,代码,块高,亮的,解决,方法,

 

无论建博客网站还是CMS类型网站,很多都需要代码高亮,dedestudy.cn/' target='_blank'>织梦dedeCMS 是国内比较优秀的CMS建站系统之一,不像Wordpress一样有大把大 把的插件可用,我用的是最新的dedeCMS 5.7,在网上搜了很长时间资料,大都写的是CKEditor和SyntaxHighlighter整合的文章,但是dedecms将ckeditor做 了集成,和一般的只针对于ckeditor对config.js修改不同。所以只能自己琢磨修改了,现将方法写出供站长朋友们参考:

一、首先去SyntaxHighlighter官方网站下载,网址:http://alexgorbatchev.com/SyntaxHighlighter/download/,建议下载2.1版本,3.0版本的貌似不支持自动换行,这里使用的是2.1.382版本。将下载的文件解压在syntaxHighlight文件夹里,去除里面无用的文件,只留下scripts和styles文件夹。

二、新建dialogs文件夹,在里面新建一个名为syntaxhighlight.js的文件,因代码量过大,不宜贴出,请直接下载syntaxhighlight.js

如果想修改代码区域的样式请在以下代码处修改<table>标签里的样式。

  onOk : function() { 

                             var i = this.getParentEditor(); 
                             var h = i.getSelection(); 
                             var g = h.getStartElement(); 
                             var l = g && g.getAscendant("pre", true); 
                             var j = f(); 
                             this.commitContent(j); 
                             var k = e(j); 
                             var m = CKEDITOR.dom.element 
                                     .createFromHtml(‘<table style="border:1px solid #EAED9C;width:660px;"><tr><td><pre class="’ + k + ‘">’
                                             + c(j.code) +"</pre></td></tr><table>"); 
                             if (l) { 
                                 m.insertBefore(l); 
                                 l.remove() 
                             } else { 
                                 i.insertElement(m) 
                             } 
                         },

三、然后新建images文件夹,存放一个syntaxhighlight.gif图片文件,该图片文件在编辑器工具栏上显示,可以使用16*16像素的图片

四、新建lang文件夹,是语言包,里面有两个文件,一个是中文cn.js一个是英文en.js,代码内容如下:

 en.js代码如下:

  CKEDITOR.plugins.setLang(‘syntaxhighlight’, ‘en’, 
 { 
     syntaxhighlight: 
     { 
         title: ‘Add or update a code snippet’, 
         sourceTab: ‘Source code’, 
         langLbl: ‘Select language’, 
         advancedTab: ‘Advanced’, 
         hideGutter: ‘Hide gutter’, 
         hideGutterLbl: ‘Hide gutter & line numbers.’, 
         hideControls: ‘Hide controls’, 
         hideControlsLbl: ‘Hide code controls at the top of the code block.’, 
         collapse: ‘Collapse’, 
         collapseLbl: ‘Collapse the code block by default. (controls need to be turned on)’, 
         showColumns: ‘Show columns’, 
         showColumnsLbl: ‘Show row columns in the first line.’, 
         lineWrap: ‘Disable line wrapping’, 
         lineWrapLbl: ‘Switch off line wrapping.’, 
         lineCount: ‘Default line count’, 
         highlight: ‘Highlight lines’, 
         highlightLbl: ‘Enter a comma seperated lines of lines you want to highlight, eg <em>3,10,15</em>.’
     } 
 });

cn.js代码如下:

 CKEDITOR.plugins.setLang(‘syntaxhighlight’, ‘cn’, 
 { 
     syntaxhighlight: 
     { 
         title: ‘添加或更新代码’, 
         sourceTab: ‘代码’, 
         langLbl: ‘选择语言’, 
         advancedTab: ‘高级’, 
         hideGutter: ‘隐藏分割线’, 
         hideGutterLbl: ‘隐藏分割线和行号’, 
         hideControls: ‘隐藏工具栏’, 
         hideControlsLbl: ‘隐藏浮动工具栏’, 
         collapse: ‘代码折叠’, 
         collapseLbl: ‘默认折叠代码块 (需要启用工具栏)’, 
         lineWrap: ‘自动换行’, 
         lineWrapLbl: ‘关闭自动换行’, 
         autoLinks: ‘自动链接’, 
         autoLinksLbl: ‘不自动转换超链接’, 
         lineCount: ‘起始行号’, 
         highlight: ‘高亮行号’, 
         highlightLbl: ‘输入以逗号分隔的行号, 如 <em>3,10,15</em>.’
     } 
 });

五、新建plugin.js文件,该文件是ckeditor插件必须得文件,里面是对该插件的一些配置,代码如下:

CKEDITOR.plugins.add("syntaxhighlight", { 
     requires : [ "dialog" ], 
     lang : [ "cn" ], 
     init : function(a) { 
         var b = "syntaxhighlight"; 
         var c = a.addCommand(b, new CKEDITOR.dialogCommand(b)); 
         c.modes = { 
             wysiwyg : 1, 
             source : 1 
         }; 
         c.canUndo = false; 
         a.ui.addButton("Code", { 
             label : a.lang.syntaxhighlight.title, 
             command : b, 
             icon : this.path + "images/syntaxhighlight.gif"
         }); 
         CKEDITOR.dialog.add(b, this.path + "dialogs/syntaxhighlight.js") 
     } 
 });

六、由于dedecms 5.7自己集成了一个dedepage插件,用来添加ckeditor自定义插件,在/include/ckeditor/dedepage文件夹下,打开plugin.js文件在最后面添加:

requires : ['syntaxhighlight'],其中syntaxhighlight为代码高亮插件的文件夹名,添加完之后的代码如下:

     // Register a plugin named "dedepage". 
    function() 
    { 
        CKEDITOR.plugins.add( ‘dedepage’, 
        { 
            init : function( editor ) 
            { 
                // Register the command. 
                editor.addCommand( ‘dedepage’,{ 
                    exec : function( editor ) 
                    { 
                        // Create the element that represents a print break. 
                        // alert(‘dedepageCmd!’); 
                        editor.insertHtml("分页副标题"); 
                    } 
                }); 
                // alert(‘dedepage!’); 
                // Register the toolbar button. 
                editor.ui.addButton( ‘MyPage’, 
                { 
                    label : ‘插入分页符’, 
                    command : ‘dedepage’, 
                    icon: ‘images/dedepage.gif’
                }); 
                // alert(editor.name); 
            }, 
            requires : [ 'fakeobjects' ], 
            requires : ['syntaxhighlight'] 
        }); 
    })();

注:将上段代码中的“分页副标题 ”改为以下代码:

七、修改/include/ckeditor/ckeditor.inc.php文件,在$toolbar['Basic']数组的最后一行添加元素Code,修改后代码如下:

 

 $toolbar['Basic'] = array( 
             array( ‘Source’,’-’,’Templates’), 
             array( ‘Cut’,’Copy’,’Paste’,’PasteText’,’PasteFromWord’,’-’,’Print’), 
             array( ‘Undo’,’Redo’,’-’,’Find’,’Replace’,’-’,’SelectAll’,’RemoveFormat’), 
             array( ‘ShowBlocks’),array(‘Image’,’Flash’),array(‘Maximize’),’/’, 
             array( ‘Bold’,’Italic’,’Underline’,’Strike’,’-’), 
             array( ‘NumberedList’,’BulletedList’,’-’,’Outdent’,’Indent’,’Blockquote’), 
             array( ‘JustifyLeft’,’JustifyCenter’,’JustifyRight’,’JustifyBlock’), 
             array( ‘Table’,’HorizontalRule’,’Smiley’,’SpecialChar’), 
             array( ‘Link’,’Unlink’,’Anchor’),’/’, 
             array( ‘Styles’,’Format’,’Font’,’FontSize’), 
             array( ‘TextColor’, ‘BGColor’, ‘MyPage’,’Code’) 
         );

  至此,编辑器的修改已经完成,修改后的syntaxhighlight文件夹文件目录结构图如下图:

  将syntaxhighlight文件夹上传到/include/ckeditor/plugins/文件夹下,打开后台,添加文章试一下,看看编辑器的上最后一行是否出现了如图所示的按钮:

  点击按钮弹出如下图所示的对话框输入代码,并且可以切换到高级选项对代码高亮显示做一些配置:

八、 但是光这些还不够,还要在文章模板文件/templets/default/article_article.htm文件里引入高亮显示的笔刷JS文件和 CSS文件,由于是需要引入很多JS,所以建议将引入的代码放在</body>标签之前,等待前面的网页加载完后加载,进行显示。

 引入代码如下:

  <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shCore.js"> </script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJava.js"></script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJScript.js"></script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPhp.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushScala.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushSql.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushVb.js"></script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushXml.js"></script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushBash.js"></script> 
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCpp.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCSharp.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/cripts/shBrushCss.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDelphi.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDiff.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushGroovy.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPlain.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPython.js"></script> 
 <script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushRuby.js"></script> 
 <link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shCore.css"/> 
 <link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shThemeDefault.css"/> 
 <script type="text/javascript"> 
     SyntaxHighlighter.config.clipboardSwf = ‘/include/ckeditor/plugins/syntaxhighlight/scripts/clipboard.swf’; 
     SyntaxHighlighter.all(); 
 </script>

 最后发表并生成的文章页面效果图如下:

  当然,该整合也有点缺点,就是在html页面页面中可能会引入大量的JS文件,加载起来可能会比较慢,另外可拓展性不强,我也会不定期优化该插件,也希望各位网友能提出意见。
