How to add a custom button to the toolbar that calls a JavaScript function?

I'd like to add a button to 开发者_运维技巧the toolbar that calls a JavaScript function like Tada()?

Any ideas on how to add this?

Also there is a nice way allowing one to add the button without creating plugin.

html:

<textarea id="container">How are you!</textarea>

javascript:

editor = CKEDITOR.replace('container'); // bind editor

editor.addCommand("mySimpleCommand", { // create named command
    exec: function(edt) {
        alert(edt.getData());
    }
});

editor.ui.addButton('SuperButton', { // add new button and bind our command
    label: "Click me",
    command: 'mySimpleCommand',
    toolbar: 'insert',
    icon: 'https://avatars1.githubusercontent.com/u/5500999?v=2&s=16'
});

I am in the process of developing a number of custom Plugins for CKEditor and here's my survival pack of bookmarks:

• A StackOverflow post linking to and talking about a plugins tutorial that got me started (Tim Down already mentioned this)
• A number of ready-made plugins for FCK and CKEditor that may improve one's understanding of the system
• The Blog of AlfonsoML, one of the developers, lots of valuable stuff there, e.g. Plugin localization in CKEditor
• Interaction between dialog buttons and a IFrame dialog, with input from Garry Yao, one of the developers
• The forums are not as bad as they look, there are some hidden gems there. Make sure you search there, well, if not first, then at least second or third.

For your purpose, I would recommend look at one of the plugins in the _source/plugins directory, for example the "print" button. Adding a simple Javascript function is quite easy to achieve. You should be able to duplicate the print plugin (take the directory from _source into the actual plugins/ directory, worry about minification later), rename it, rename every mention of "print" within it, give the button a proper name you use later in your toolbar setup to include the button, and add your function.

See this URL for a easy example http://ajithmanmadhan.wordpress.com/2009/12/16/customizing-ckeditor-and-adding-a-new-toolbar-button/

There are a couple of steps:

1) create a plugin folder

2) register your plugin (the URL above says to edit the ckeditor.js file DO NOT do this, as it will break next time a new version is relased. Instead edit the config.js and add a line like so

config.extraPlugins = 'pluginX,pluginY,yourPluginNameHere'; 

3) make a JS file called plugin.js inside your plugin folder Here is my code

(function() {
    //Section 1 : Code to execute when the toolbar button is pressed
    var a = {
        exec: function(editor) {
            var theSelectedText = editor.getSelection().getNative();
            alert(theSelectedText);
        }
    },

    //Section 2 : Create the button and add the functionality to it
    b='addTags';
    CKEDITOR.plugins.add(b, {
        init: function(editor) {
            editor.addCommand(b, a);
            editor.ui.addButton("addTags", {
                label: 'Add Tag', 
                icon: this.path+"addTag.gif",
                command: b
            });
        }
    }); 
})();

In case anybody is interested, I wrote a solution for this using Prototype. In order to get the button to appear correctly, I had to specify extraPlugins: 'ajaxsave' from inside the CKEDITOR.replace() method call.

Here is the plugin.js:

CKEDITOR.plugins.add('ajaxsave',
{
    init: function(editor)
    {
    var pluginName = 'ajaxsave';

    editor.addCommand( pluginName,
    {
        exec : function( editor )
        {
            new Ajax.Request('ajaxsave.php',
            {
                method:     "POST",
                parameters: { filename: 'index.html', editor: editor.getData() },
                onFailure:  function() { ThrowError("Error: The server has returned an unknown error"); },
                on0:        function() { ThrowError('Error: The server is not responding. Please try again.'); },
                onSuccess:  function(transport) {

                    var resp = transport.responseText;

                    //Successful processing by ckprocess.php should return simply 'OK'. 
                    if(resp == "OK") {
                        //This is a custom function I wrote to display messages. Nicer than alert() 
                        ShowPageMessage('Changes have been saved successfully!');
                    } else {
                        ShowPageMessage(resp,'10');
                    }
                }
            });
        },

        canUndo : true
    });

    editor.ui.addButton('ajaxsave',
    {
        label: 'Save',
        command: pluginName,
        className : 'cke_button_save'
    });
    }
});

CKEditor 4

There are handy tutorials in the official CKEditor 4 documentation, that cover writing a plugin that inserts content into the editor, registers a button and shows a dialog window:

• Creating a CKEditor 4 Plugin in 20 Lines of Code
• Creating a Simple CKEditor Plugin

If you read these two, move on to Integrating Plugins with Advanced Content Filter.

CKEditor 5

So far there is one introduction article available:

CKEditor 5 Framework: Quick Start - Creating a simple plugin

You'll need to create a plug-in. The documentation for CKEditor is very poor for this, especially since I believe it has changed significantly since FCKEditor. I would suggest copying an existing plug-in and studying it. A quick google for "CKEditor plugin" also found this blog post.

You can add the button image as follows:

CKEDITOR.plugins.add('showtime',   //name of our plugin
{    
    requires: ['dialog'], //requires a dialog window
    init:function(a) {
  var b="showtime";
  var c=a.addCommand(b,new CKEDITOR.dialogCommand(b));
  c.modes={wysiwyg:1,source:1}; //Enable our plugin in both modes
  c.canUndo=true;
 
  //add new button to the editor
  a.ui.addButton("showtime",
  {
   label:'Show current time',
   command:b,
   icon:this.path+"showtime.png"   //path of the icon
  });
  CKEDITOR.dialog.add(b,this.path+"dialogs/ab.js") //path of our dialog file
 }
});

Here is the actual plugin with all steps described.

There are code samples and step-by-step guide about building your own CKEditor plugin with custom button.

If you have customized the ckeditor toolbar then use this method:

var editor = CKEDITOR.replace("da_html", {
  disableNativeSpellChecker: false,
  toolbar: [{
      name: "clipboard",
      items: ["Cut", "Copy", "Paste", "PasteText", "PasteFromWord", "-", "Undo", "Redo"]
    },
    "/",
    {
      name: "basicstyles",
      items: ["Italic"]
    },
    {
      name: "paragraph",
      items: ["BulletedList"]
    },
    {
      name: "insert",
      items: ["Table"]
    },
    "/",
    {
      name: "styles",
      items: ["Styles", "Format", "Font", "FontSize"]
    },
    {
      name: "colors",
      items: ["TextColor", "BGColor"]
    },
    {
      name: "tools",
      items: ["Maximize", "saveButton"]
    },
  ]
});

editor.addCommand("mySaveCommand", { // create named command
  exec: function(edt) {
    alert(edt.getData());
  }
});

editor.ui.addButton("saveButton", { // add new button and bind our command
  label: "Click me",
  command: "mySaveCommand",
  toolbar: "insert",
  icon: "https://i.stack.imgur.com/IWRRh.jpg?s=328&g=1"
});

<textarea id="da_html">How are you!</textarea>

Working code in jsfiddle due to some security issue of stackoverflow: http://jsfiddle.net/k2vwqoyp/

There might be Several plugins but one may use CSS for creating button. First of all click on Source button mentioned in Editor then paste the button code over there, As I use CSS to create button and added href to it.

<p dir="ltr" style="text-align:center"><a href="https://play.google.com/store/apps/details?id=com.mobicom.mobiune&hl=en" style="background-color:#0080ff; border: none;color: white;padding: 6px 20px;text-align: center;text-decoration: none;display: inline-block;border-radius: 8px;font-size: 15px; font-weight: bold;">Open App</a></p>

This is the Button Written Open App over It. You May change the Color as i am using #0080ff (Light Blue)
