How does it works?

plugin connects a JavaScript object with HTML elements according to data-model attribute
data-model must contain object property name
in INPUTS, SELECTS and TEXTAREAS plugin uses two way bindings
model is updated when is changed value in a INPUT/SELECT/TEXTAREA or manually

HTML attributes:

<div id="container" data-name="my-model-1">
	<div><input type="text" data-model="property" /></div>
	<div data-model="property"></div>
	<div data-model="property.next.property"></div>
	<div data-model="created" data-format="your-custom-format"></div>
	<div data-model="tags" data-custom="your-custom-identificator"></div>
	<div data-model="html" data-encode="false"></div>
</div>

data-name="{String}" is a container name
data-encode="{Boolean}" enable HTML encoding/decoding string (default: true)
data-format="{String}" calls $.bindings.format() delegate
data-custom="{String}" calls $.bindings.custom() delegate

$.bindings('create')(model, [template]);

Create bindings.

$('#form').bindings('create')({ firstname: 'Peter', lastname: 'Širka' });

// or (XHR)

$('#form').bindings('create')({ firstname: 'Peter', lastname: 'Širka' }, '/my-form.html');

// or (HTML)

$('#form').bindings('create')({ firstname: 'Peter', lastname: 'Širka' }, '<input type="text" data-model="firstname" /><span>your firstname: <b data-model="first-name"></b></span>');

// or (SELECTOR)

$('#form').bindings('create')({ firstname: 'Peter', lastname: 'Širka' }, '#template-selector');

$.bindings('download')(url, [template]);

Create bindings.

$('#form').bindings('download')('/model.json');

// or

$('#form').bindings('download')('/model.json', '<input type="text" data-model="firstname" /><span>your firstname: <b data-model="first-name"></b></span>');

// or

$('#form').bindings('download')('/model.json', '#template-selector');

$.bindings('json')(query, [template]);

Create bindings.

<script type="text/plain" id="model-selector">{"firstname":"Peter","lastname":"Širka"}</script>

$('#form').bindings('json')('#model-selector');

// or

$('#form').bindings('json')('#model-selector', '<input type="text" data-model="firstname" /><span>your firstname: <b data-model="first-name"></b></span>');

// or

$('#form').bindings('json')('#model-selector', '#template-selector');

$.bindings('refresh');

Refresh values in HTML.

$('#form').bindings('refresh');

$.bindings('destroy');

Destroy bindings.

$('#form').bindings('destroy');

$.bindings('default');

Default bindings. As default model is used a model from bindings('create').

$('#form').bindings('default');

$.bindings('validate');

Validate a model.

$('#form').bindings('validate');

$.bindings('set')(path, value);

Rewrite an existing value.

$('#form').bindings('set')('firstname', 'Janko');

// or

$('#form').bindings('set')('user.firstname', 'Janko');

// or

$('#form').bindings('set')('tags', function(value) {
	value.push('new-tag');
	return value;
});

$.bindings('get')(path);

Get an existing value.

$('#form').bindings('get')('firstname');

// or

$('#form').bindings('get')('user.firstname');

$.bindings('update')(model);

Update a model.

$('#form').bindings('update')({ firstname: 'Janko', lastname: 'Izaak' });

// OR

$('#form').bindings('update')(function(model) {
	model.firstname = 'Peter';
	model.lastname = 'Širka';
	return model;
});

$.bindings('model') or $.bindings();

Get a model.

$('#form').bindings();

// or

$('#form').bindings('model');

// OUTPUT: { firstname: 'Janko', lastname: 'Izaak' }

$.bindings('send')(url, [options], [callback(err, data)])

Send a model via XHR as application/json.

$('#form').bindings('send')('/form/submit/');

// or

$('#form').bindings('send')('/form/submit/', { type: 'PUT' });

$.bindings('change')([isChange])

Was a model changed?

console.log($('#form').bindings('change')());

// or, custom set:

$('#form').bindings('change')(true);

Delegates

$.bindings.prepare(path, value, format, model, name)

Prepare current value from an INPUT to a MODEL. Always must return a value.

$.bindings.prepare = function(path, value, format, model, name) {
	// EXAMPLE:
	// this === current element with data-model attribute
	if (path === 'age')
		return parseInt(value);
	return value;
};

$.bindings.format(path, value, format, model)

Format current value from a MODEL to a HTML. Always must return a value.

<!-- ENCODED -->
<div data-model="age" data-format="years <b>old</b>"></div>

<!-- OR RAW -->
<div data-model="age" data-format="years <b>old</b>" data-encode="false"></div>

$.bindings.format = function(path, value, format, model, name) {
	// EXAMPLE:
	// this === current element with data-model attribute
	if (path === 'age')
		return value + ' ' + format;
	return value;
};

$.bindings.custom(path, value, format, model, name)

Format current value from a MODEL to HTML. Always must return a value.

<div data-model="age" data-custom="custom-value"></div>

$.bindings.custom = function(path, value, custom, model, name) {
	// EXAMPLE:
	// this === current element with data-model and data-custom attribute

		return value + ' years old';
	return value;
};

$.bindings.validation(path, value, model, name)

$.bindings.validation = function(path, value, model, name) {

	switch (path) {
		case 'age':
			return value > 17 && value < 50;
	}

	return true;
};

$.bindings.watch(isValid, path, value, model, name)
