Bootstrap-wysiwyg minimal usage ( supoort added without jQuery HotKeys and Font-Awesome.css )

bootstrap-wysiwyg

A tiny Bootstrap and jQuery based WYSIWYG rich text editor based on the browser function execCommand.

This project was originally built for MindMup and has now been adapted and modified to suit a wide range of projects.

Development is active, and ongoing.

Features

• Automatically binds standard hotkeys for common operations on Mac and Windows
• Allows a custom built toolbar with no magic markup generators enabling the web site to use all the goodness of Bootstrap
• Does not force any styling - it's all up to you
• Uses standard browser features, no magic non-standard code, toolbar and keyboard configurable to execute any supported browser command
• Does not create a separate frame, backup text areas etc - instead keeps it simple and runs everything inline in a DIV
• (Optionally) cleans up trailing whitespace and empty divs and spans
• Requires a modern browser (See SUPPORTED)
• Supports mobile devices (See SUPPORTED)
• Supports multiple instances
• HTML Sanitization
• Drag and drop files to insert images
• Supports image upload
• Supports image capture on mobile devices
• Events

Basic Usage

$('#editor').wysiwyg();

Don't forget to style your editor div:

#editor {overflow:scroll; max-height:300px}

If you want to use this for a mobile web site, make sure to read about how to style it to optimise mobile screen usage and experience (please note that this demo page isn't optimised for mobile access).

Optionally, also create a toolbar (see the source of this page for an example):

<div class="btn-toolbar" data-role="editor-toolbar"
        data-target="#editor">
  ...
</div> 

In the toolbar, execute simple commands by adding a data-edit attribute to a link.

<a data-edit="bold">...</a>

execute more complex commands by adding an argument after a blank or providing an input with a data-edit command (the input value is used as an argument). In case of file inputs, the file contents are read in using the FileReader API and used as the command value.

<a data-edit="fontName Arial">...</a>
...
<input type="text" data-edit="createLink"/>
...
<input type="file" data-edit="insertImage" />

Use standard jQuery methods to access and set content and focus. You can also ask for cleaned up HTML content:

$('#editor').cleanHtml()

Customising

You can assign commands to hotkeys and toolbar links. For a toolbar link, just put the execCommand command name into a data-edit attribute. For more info on execCommand, see the QuirksMode and Mozilla Developer documentation.

<div class="btn-toolbar" data-role="editor-toolbar" data-target="#editor">
  <a class="btn btn-large" data-edit="bold"><i class="icon-bold"></i></a>
</div>

To pass arguments to a command, separate a command with a space.

  <a data-edit="fontName Arial">...</a>

You can also use input type='text' with a data-edit attribute. When the value is changed, the command from the data-edit attribute will be applied using the input value as the command argument

<input type="text" data-edit="createLink">

If the input type is file, when a file is selected the contents will be read in using the FileReader API and the data URL will be used as the argument

<input type="file" data-edit="insertImage">

To change hotkeys, specify the map of hotkeys to commands in the hotKeys option. For example:

$('#editor').wysiwyg({
  hotKeys: {
    'ctrl+b meta+b': 'bold',
    'ctrl+i meta+i': 'italic',
    'ctrl+u meta+u': 'underline',
    'ctrl+z meta+z': 'undo',
    'ctrl+y meta+y meta+shift+z': 'redo'
  }
});

Events

Change

Fired whenever anything changes. See this example events.html

$('#editor').wysiwyg().on('change', function(){
	alert('something has been changed on the editor');
});

Styling for mobile devices

This editor should work pretty well with mobile devices, but you'll need to consider the following things when styling it:

• keyboards on mobile devices take a huge part of the screen
• having to scroll the screen to touch the toolbar can cause the editing component to lose focus, and the mobile device keyboard might go away
• mobile devices tend to move the screen viewport around to ensure that the focused element is shown, so it's best that the edit box is glued to the top

For the content attachment editor on MindMup, we apply the following rules to mobile device styling:

• edit box is glued to the top, so the focus doesn't jump around
• toolbar is below the edit box
• on portrait screens, edit box size is 50% of the screen
• on landscape screens, edit box size is 30% of the screen
• as the screen gets smaller, non-critical toolbar buttons get hidden into a "other" menu

Dependencies

• jQuery
• jQuery HotKeys
• Bootstrap

History

The original version of this code (below) appeared to be no longer maintained. There were a number of outstanding changes which needed to be merged in and a few which included performance and feature improvements. These have now been included in this master branch.

I'll keep an eye out for future changes/improvements and pull them in as required.
