Hooks

Hooks are fired at different times through Behave. To add your own hooks to extend the functionality of Behave, use the BehaveHooks function.

BehaveHooks.add('keydown', function(data){
    // Your Code
});

The add function accepts two parameters, the hook name, and the function.

The following hook names are available for use:

<dt><span>enter:before</span></dt>
<dd><p>Called before inserting the text triggered by the enter key</p></dd>
<dt><span>enter:after</span></dt>
<dd><p>Called after inserting the text triggered by the enter key</p></dd>

<dt><span>delete:before</span></dt>
<dd><p>Called before deleting the text triggered by the delete key</p></dd>
<dt><span>delete:after</span></dt>
<dd><p>Called after deleting the text triggered by the delete key</p></dd>

<dt><span>tab:before</span></dt>
<dd><p>Called before inserting the text triggered by the tab key</p></dd>
<dt><span>tab:after</span></dt>
<dd><p>Called after inserting the text triggered by the tab key</p></dd>

<dt><span>keyup</span></dt>
<dd><p>Called before modifying the text triggered by the keyup event</p></dd>
<dt><span>keydown</span></dt>
<dd><p>Called after modifying the text triggered by the keydown event</p></dd>

Each hook excluding the init hooks accept a single parameter, an object with the following information:

{
    caret: {
	    pos: 5
    },
    editor: {
	    element: textarea
	    levelsDeep: 1,
	    text: 'foo{}'
    },
    lines: {
	    current: 1,
	    total: 1
    }
}
