Use JavaScript to add Audio tags to Kindeditor custom buttons_javascript skills
The process is relatively simple and mainly consists of the following steps:
- Register plug-in (button, Lang, htmlTags, plug-in script)
- Modified based on media plug-in code
Register plugin
First, configure the kindeditor parameters globally:
KindEditor.lang({ audio : 'MP3' }); KindEditor.options.htmlTags['audio'] = ['src','controls','autoplay','type']; KindEditor.options.htmlTags['source'] = ['src','controls','autoplay','type'];
In the place where you initialize the editor, configure the button list items parameter and put
'audio'
Put it in the right place:
KindEditor.ready(function(K) { editor = K.create('#info,#spread_info', { //其他配置省略... items : [ 'source', '|', 'undo', 'redo', '|', 'preview', 'print', 'template', 'code', 'cut', 'copy', 'paste', 'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright', 'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript', 'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/', 'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image', 'multiimage', '|' ,'table', 'hr', 'emoticons', 'baidumap', 'pagebreak', 'anchor', 'link', 'unlink', '|', 'about','audio' ] });
For easier reading, I put the audio button at the end, after the "Help" label.
In order for the button to be displayed, we also need to specify the css style:
<style> .ke-icon-audio { background-position: 0px -528px; width: 16px; height: 16px; } </style>
For convenience, I directly used the icons of the built-in audio and video buttons. To customize the icons, please manually specify the background style attribute.
Finally, create the script
kindeditor/plugins/audio/audio.js
The audio directory is created manually.
We put
plugins/media/media.js
to audio.js, and then start modifying it.
Modify media plug-in
The main thing is to remove some useless attributes, such as width, height, autoplay, etc., and modify the inserted code part, and manually build the html code of the "audio" tag.
/** * Created by admin on 15-5-6. */ KindEditor.plugin('audio', function(K) { var self = this, name = 'audio', lang = self.lang(name + '.'), allowMediaUpload = K.undef(self.allowMediaUpload, true), allowFileManager = K.undef(self.allowFileManager, false), formatUploadUrl = K.undef(self.formatUploadUrl, true), uploadJson = K.undef(self.uploadJson, self.basePath + 'php/upload_json.php'); self.plugin.media = { edit : function() { var html = [ '<div style="padding:20px;">', //url '<div class="ke-dialog-row">', '<label for="keUrl" style="width:60px;">MP3 URL</label>', '<input class="ke-input-text" type="text" id="keUrl" name="url" value="" style="width:160px;" /> ', '<input type="button" class="ke-upload-button" value="上传" /> ', '</div>', '</div>' ].join(''); var dialog = self.createDialog({ name : name, width : 450, height : 230, title : self.lang(name), body : html, yesBtn : { name : self.lang('yes'), click : function(e) { var url = K.trim(urlBox.val()), width = widthBox.val(), height = heightBox.val(); if (url == 'http://' || K.invalidUrl(url)) { alert(self.lang('invalidUrl')); urlBox[0].focus(); return; } if (!/^\d*$/.test(width)) { alert(self.lang('invalidWidth')); widthBox[0].focus(); return; } if (!/^\d*$/.test(height)) { alert(self.lang('invalidHeight')); heightBox[0].focus(); return; } var html = '<p><audio src="'+url+'" controls="controls"></audio><br/></p>'; self.insertHtml(html).hideDialog().focus(); } } }), div = dialog.div, urlBox = K('[name="url"]', div), viewServerBtn = K('[name="viewServer"]', div), widthBox = K('[name="width"]', div), heightBox = K('[name="height"]', div), autostartBox = K('[name="autostart"]', div); urlBox.val('http://'); if (allowMediaUpload) { var uploadbutton = K.uploadbutton({ button : K('.ke-upload-button', div)[0], fieldName : 'imgFile', url : K.addParam(uploadJson, 'dir=audio'), afterUpload : function(data) { dialog.hideLoading(); if (data.error === 0) { var url = data.url; if (formatUploadUrl) { url = K.formatUrl(url, 'absolute'); } urlBox.val(url); if (self.afterUpload) { self.afterUpload.call(self, url); } alert(self.lang('uploadSuccess')); } else { alert(data.message); } }, afterError : function(html) { dialog.hideLoading(); self.errorDialog(html); } }); uploadbutton.fileBox.change(function(e) { dialog.showLoading(self.lang('uploadLoading')); uploadbutton.submit(); }); } else { K('.ke-upload-button', div).hide(); } if (allowFileManager) { viewServerBtn.click(function(e) { self.loadPlugin('filemanager', function() { self.plugin.filemanagerDialog({ viewType : 'LIST', dirName : 'media', clickFn : function(url, title) { if (self.dialogs.length > 1) { K('[name="url"]', div).val(url); self.hideDialog(); } } }); }); }); } else { viewServerBtn.hide(); } var img = self.plugin.getSelectedMedia(); if (img) { var attrs = K.mediaAttrs(img.attr('data-ke-tag')); urlBox.val(attrs.src); widthBox.val(K.removeUnit(img.css('width')) || attrs.width || 0); heightBox.val(K.removeUnit(img.css('height')) || attrs.height || 0); autostartBox[0].checked = (attrs.autostart === 'true'); } urlBox[0].focus(); urlBox[0].select(); }, 'delete' : function() { self.plugin.getSelectedMedia().remove(); } }; self.clickToolbar(name, self.plugin.media.edit); });
At this point, the entire plug-in is basically finished.
It should be noted that uploading files uses the common configuration uploadJson parameter, but a get parameter "dir=audio" will be automatically added when uploading to facilitate background recognition:
url : K.addParam(uploadJson, 'dir=audio'),

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
