本篇文章给大家推荐一款炒鸡好用的Thinkphp富文本编辑器--CKEditor,下面给大家介绍一下使用CKEditor的方法,希望对大家有所帮助!
最近一直在做Thinkphp后端开发,之前都是使用layui的富文本编辑器,layui的优点是简单易用,但缺点也比较明显,就是编辑器功能比较少,无意中发现别人的项目里使用的是CKEditor富文本编辑器,感觉还阔以!下面让我们一起来学习如何使用CKEditor。
Ckeditor4下载地址(本教程选择的是CKEditor 4.16版本):
https://ckeditor.com/ckeditor-4/download/
一、在页面中引入ckeditor核心文件ckeditor.js
- <script type="text/javascript" src="ckeditor/ckeditor.js"></script>
二、在使用编辑器的地方插入HTML控件
- <textarea id="content" name="content" cols="30" rows="2"></textarea>
三、将相应的控件替换成编辑器代码
- <script type="text/javascript">
- var editor;
- window.onload = function()
- {
- editor = CKEDITOR.replace( 'content', {
- filebrowserImageUploadUrl : '{:url("@admin/article/uploadPic")}',//上传图片的后端URL地址
- image_previewText : ' '///去掉图片上传预览区域显示的文字
- });
- };
- </script>
四、开启上传功能(上传功能被隐藏了,所以需要开启)
在ckeditor/plugins/image/dialogs/image.js文件中,搜索:id:"Upload",hidden:!0,把 !0改成false
五、thinkphp后端上传文件的方法
4.10版本之后,官方文档要求图片上传成功后,返回json格式,示例如下:
上传成功返回:
- {
- "uploaded": 1,
- "fileName": "demo.jpg",
- "url": "/files/demo.jpg"
- }
- {
- "uploaded": 1,
- "fileName": "test.jpg",
- "url": "/files/test.jpg",
- "error": {
- "message": "A file with the same name already exists. The uploaded file was renamed to \"test.jpg\"."
- }
- }
上传失败返回:
- {
- "uploaded": 0,
- "error": {
- "message": "The file is too big."
- }
- }
后端上传图片的代码:
- /**
- * @name='上传图片'
- */
- public function uploadPic()
- {
- //注明:ckeditor是使用ajax上传图片,而不是用表单提交,因此不能使用request()->file()接收图片,只能用$_FILES
- $name = $_FILES['upload']['name'];
- $size = $_FILES['upload']['size'];
- if($size > 1024*2*1000){
- $arr= array(
- "uploaded" => 0,
- "error" => "上传的图片大小不能超过2M"
- );
- exit(json_encode($arr));
- }
- $extension = pathInfo($name,PATHINFO_EXTENSION);
- $types = array("jpg","bmp","gif","png");
- if(in_array($extension,$types)){
- //以日期为文件夹名,如public/uploads/20210327/
- $dateFolder = date("Ymd",time());
- $path = ROOT_PATH . 'public/uploads/'.$dateFolder.DS;
- if(!file_exists($path)){
- mkdir($path,0777,true);
- }
- $img_name = str_replace('.','',uniqid("",TRUE)).".".$extension; //图片名称
- $save_path = $path.$img_name; //保存路径
- $img_path = '/uploads/'.$dateFolder.DS.$img_name; //图片路径
- move_uploaded_file($_FILES['upload']['tmp_name'],$save_path);
- $arr= array(
- "uploaded" => 1,
- "fileName" => $img_name,
- "url" => $img_path
- );
- }else{
- $arr= array(
- "uploaded" => 0,
- "error" => "图片格式不正确(只能上传.jpg/.gif/.bmp/.png类型的文件)"
- );
- }
- return json_encode($arr);
- }
六、js里获取ckeditor里的内容
- <script type="text/javascript">
- var editor;
- $(function() {
- editor = CKEDITOR.replace('content');
- })
- editor.document.getBody().getText();//取得纯文本
- editor.document.getBody().getHtml();//取得html文本
- </script>
七、使用颜色插件
1、需要下载三个插件(缺一不可),下载地址:
https://ckeditor.com/cke4/addon/colorbutton
https://ckeditor.com/cke4/addon/floatpanel
https://ckeditor.com/cke4/addon/panelbutton
2、下载好的插件解压到ckeditor\plugins目录里
3、加载插件
方式一:在ckeditor/config.js文件中,添加插件的配置,如下:
- CKEDITOR.editorConfig = function( config ) {
- ...省略前面的代码
- //加载插件
- config.extraPlugins = 'colorbutton,panelbutton,floatpanel';
- }
方式二:在js里初始化editor时,添加插件的配置
- <script type="text/javascript">
- var editor;
- window.onload = function()
- {
- editor = CKEDITOR.replace( 'content', {
- filebrowserImageUploadUrl : '{:url("@admin/article/uploadPic")}',//上传图片的后端URL地址
- image_previewText : ' ',///去掉图片上传预览区域显示的文字
- extraPlugins: 'colorbutton',//使用颜色插件
- });
- };
- </script>
八、自定义工具栏配置
在ckeditor/config.js文件中设置
- CKEDITOR.editorConfig = function( config ) {
- //工具栏设置
- config.toolbar = 'MyToolbar';
- config.toolbar_Full = [
- { name: 'document', items : [ 'Source','-','Save','NewPage','DocProps','Preview','Print','-','Templates' ] },
- { name: 'clipboard', items : [ 'Cut','Copy','Paste','PasteText','PasteFromWord','-','Undo','Redo' ] },
- { name: 'editing', items : [ 'Find','Replace','-','SelectAll','-','SpellChecker', 'Scayt' ] },
- { name: 'forms', items : [ 'Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton',
- 'HiddenField' ] },
- '/',
- { name: 'basicstyles', items : [ 'Bold','Italic','Underline','Strike','Subscript','Superscript','-','RemoveFormat' ] },
- { name: 'paragraph', items : [ 'NumberedList','BulletedList','-','Outdent','Indent','-','Blockquote','CreateDiv',
- '-','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock','-','BidiLtr','BidiRtl' ] },
- { name: 'links', items : [ 'Link','Unlink','Anchor' ] },
- { name: 'insert', items : [ 'Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak','Iframe' ] },
- '/',
- { name: 'styles', items : [ 'Styles','Format','Font','FontSize' ] },
- { name: 'colors', items : [ 'TextColor','BGColor' ] },
- { name: 'tools', items : [ 'Maximize', 'ShowBlocks','-','About' ] }
- ];
- config.toolbar_Basic = [
- ['Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink','-','About']
- ];
- //自定义
- config.toolbar_MyToolbar =[
- //加粗 斜体, 下划线 穿过线 下标字 上标字
- ['Bold','Italic','Underline','Strike','Subscript','Superscript'],
- // 数字列表 实体列表 减小缩进 增大缩进
- ['NumberedList','BulletedList','-','Outdent','Indent'],
- // 左对齐 居中对齐 右对齐 两端对齐
- ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
- //超链接 取消超链接 锚点
- ['Link','Unlink','Anchor'],
- //图片 flash 表格 水平线 表情 特殊字符 分页符
- ['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
- '/',
- // 样式 格式 字体 字体大小
- ['Styles','Format','Font','FontSize'],
- //文本颜色 背景颜色
- ['TextColor','BGColor'],
- //全屏 显示区块 源码
- ['Maximize', 'ShowBlocks','-','Source']
- ],
- config.format_tags = 'p;h1;h2;h3;h4;h5;h6;pre';
- config.removeButtons = 'Underline,Subscript,Superscript';
- config.removeDialogTabs = 'image:advanced;link:advanced';
- //加载插件
- config.extraPlugins = 'colorbutton,panelbutton,floatpanel';
- };
