Usage

A simple default editor

<textarea data-bind="wysiwyg : myObservable"></textarea>

Design your own editor using http://www.tinymce.com/wiki.php/Configuration to build the wysiwygConfig object.

<textarea data-bind="wysiwyg: myObservable, wysiwygConfig: { statusbar: true }"></textarea>

Customisable default configuration NEW to v1.1.0

tinymce-knockout-binding no longer assumes a default configuration for the editor. Configuration is applied to all editor instances by setting the binding's defaults property.

    ko.bindingHandlers['wysiwyg'].defaults = {
        'plugins': [ 'link' ],
        'toolbar': 'undo redo | bold italic | bullist numlist | link',
        'menubar': false,
        'statusbar': false,
        'setup': function( editor ) {
            editor.on( 'init', function( e ) {
                console.log('wysiwyg initialised');
            });
        }
    };

Using this in conjuction with the wysiwygConfig binding allows specific editors to extend these settings.

Working with Extensions

View-model got dirty tracking? No problem. Just add the wysiwygDirty binding to maintain your model's dirty tracking. Not bothered about this? We still record if the editor was touched, just inspect your viewModel or bindingContext.$root for the isDirty flag.

<textarea data-bind="wysiwyg: myObservable, wysiwygDirty: myDirtyObservable, wysiwygExtensions: [ 'dirty' ]"></textarea>

Using the wordcount plugin? Need to extract the counter value? Simple.

<textarea data-bind="wysiwyg: myObservable,
                     wysiwygConfig: { plugins: [ 'wordcount' ] },
                     wysiwygExtensions: [ 'wordcount' ],
                     wysiwygWordCount: myCounter">
</textarea>

Write your own custom extensions

Since v1.0.2 extensions are functions called when the editor changes. To create a custom exetension simply add the following code to your script.

(function( wysiwyg ) {

	wysiwyg.extensions['mycustomextension'] = function( editor, args, allBindings, bindingContext ) {
		// your logic goes here
	};

})( ko.bindingHandlers['wysiwyg'] );

To consume your new extension;

<textarea data-bind="wysiwyg : myObservable, wysiwygExtensions: [ 'mycustomextension' ]"></textarea>
