Class: kbbcode (derived from NAWTE)
License:
NAWTE is released under the MIT License (http://opensource.org/licenses/mit-license.php)
Info:
nawte is a class to help you put together your own WYSIWYM editor. It works by hooking up to
a textarea. From there you are free to add any *function* you want via the <addFunction> method.
Any function you add will do two things: First, it will add a button to the textarea's toolbar.
Second, it will perform a TextTransform operation (this is where nawte is helpful). An example
function could be "bold". This would add a "bold" button to your textarea and perform any text
transformation required to make the text bold. The beauty of this is that, nawte doesn't depend on
any markup language. If you want your output to be html, so be it! If you prefer markdown or textile,
once again, no problems!
All the TextTransform functions (<wrapSelection>, <insert>, <replaceSelection>, <processEachLine>)
take a parameter named "isLast". This parameter is used for chaining multiple text transformation.
Setting it to false means you are going to do more transformations once the current transformation is applied.
The example code below will help clarify that. Note that if you are only doing one text transformation
in your function (for example, only wrapping the selection) you can ignore this parameter, it will be
set to "true" by default.
General Example:
(start code)
//creating a kbbcode object
kbbcode = new kbbcode('textAreaId', 'toolBarId');
//adding a "List" button that will create a new list if nothing is selected
//or make each line of the selection into a list item if some text is selected...
kbbcode.addFunction("list", function() {
selection = this.getSelection();
if (selection == "") {
this.replaceSelection("<ul>\n <li>Item 1</li>\n <li>...</li>\n</ul>");
}
else {
this.processEachLine(function(line) {
newline = " <li>" + line + "</li>";
return newline;
}, false);
// here you see the purpose of the isLast parameter... since we are applying
// more TextTransform methods to the selection, isLast must be set to false!
this.insert("<ul>\n", "before", false);
this.insert("\n</ul>", "after", true); //now isLast is set to true, because it is the last one!
}
});
(end)

/*
Constructor: kbbcode (constructor)
Creates a new kbbcode object.
Arguments:
element - a string, the ID of your textarea
list - optional, a string, the id of your toolbal (a UL element)
options - optional, an object, details below
Options:
dispatchChangeEvent - a boolean, set to true if you want to dispatch the "change" event. default: false
changeEventDelay - an integer, they delay for the periodical function that dispatches the change event. default: 200
interceptTabs - a boolean, set to true if you want the tab key to insert a tab in the text area, set to false for default tab behavior. default: true
Additional Info:
It is possible to watch the "change" event of your textarea . This event will notify you when the content
of your textarea has been changed, eighter by typing in it, or by pressing on one of the toolbar buttons.
The purpose of this is that normally, the textarea would not fire a "change" event when kbbcode inserts
text in it (or when you copy/paste some text in there too). By setting dispatchChangeEvent to true, a
periodical function will watch the textarea for any changes and fire the "change" event whenever the
content of the textarea has been changed, no matter how it was changed. You can change the delay of this
periodical function with the changeEventDelay option. The default delay is 1000ms.
Example:
(start code)
var mykbbcode = new kbbcode('myTextarea', 'myToolbar', {
dispatchChangeEvent: true,
changeEventDelay: 150,
interceptTab: true
});

Event: onchange
Fired when the content of the textarea is changed.
Details:
As mentioned above, the onchange event of the textarea won't be fired when kbbcode inserts content in it
or when content is pasted in it. By setting the "dispatchChangeEvent" option to true, this event will
be fired by a periodical function whenever the content of the textarea as changed.
The periodical function is only running when the textarea is focused, and stops when it is blured.
This can be useful if you want to create a live-preview or something like that, that way you are notified
of any changes to the textarea and can reflect it in your live preview.
Example:
I want to watch the change event of my textarea (who's id is "myText")
(start code)
$('myText').addEvent('change', function(){
console.log("My content was changed!");
});

Function: addFunction
The main concept of kbbcode, this is where you add functions (i.e. buttons) to your editor.
Arguments:
name - a string, the name of the function to add
callback - a function, what your button will do
args - optional, an object, additional HTML properties you want to add to the button
Additional Info:
This is the basic idea of kbbcode, each function you add (for example "BOLD") will add a new
button to your editor. In your callback function, you can use any of the TextTransform functions
to transform the selection, insert new text etc..
Example:
(start code)
//we will add a bold button that will surround the selection
//with <b>, </b>
mykbbcode.addFunction('bold', function() {
var selection = this.getSelection();
this.replaceSelection('<b>' + selection + '</b>');
},
{title: "Make Text Bold"});
// and we now have a bold button! Isn't that pure magic!??
// note the optional "args" argument, just pass an object with html
// properties to apply them to the newly created button, in this case
// I am setting it's title to "Make Text Bold"...
(end)
