LemonadeJS Methods

The following table lists the native LemonadeJS methods.
Method Description
Core functions
element(string, object, object)It will create the DOM elements based on a HTML template and bind the scope with the self object and return a DOM Element container.
lemonade.element(template: String, self: Object, components: Object) => DOMElement
render(DOMElement, DOMElement)It will append the new created LemonadeJS DOMElement to a DOMElement in the existing DOM.
lemonade.render(component: Function, root: HTMLElement) => void
apply(DOMElement, object, object)Bind the self scope to an existing DOMElement already in the DOM.
lemonade.apply(root: HTMLElement, self: Object, components: Object) => void
Sugar functions
set(string, self, persistence)Make the self or a data dispatcher available in the Sugar common container to be used across different components.
lemonade.set(alias: String, self: Object, persistence?: Boolean) => void
get(string)Get a self reference from the Sugar common container.
lemonade.get(alias: String) => Object | Function
dispatch(string, data)Call a data dispatcher.
lemonade.dispatch(alias: String, data: Object) => void

Apply method

In almost all examples through the website you can see that the lemonade.element creates render the HTML and binds with the self. Them the lemonade.render will append that element to the DOM. The lemonade.apply will be used when you wish to bind a self to an existing appended DOM element. Thus it would be use to bind a existing self to the already appended DOM element.

Basic Example

The following examples are basic examples on how to apply a self to an existing DOM root element. Of course this is just an example for education purposes and a better scope encapsulation should be considered.

<script src="https://lemonadejs.net/v2/lemonade.js"></script>

<div id='element'>
    <input type="button" value="Update"
        onclick="self.title = 'New title'" />

// Apply the self object to an existing HTML element already in the DOM
var self = {};
self.title = 'Hello world';
lemonade.apply(document.getElementById('element'), self);


Control an existing HTML form

The following example binds a self to an HTML form to control the values of the form elements.

<script src="https://lemonadejs.net/v2/lemonade.js"></script>

<form id='myForm'>
    <div class='form-group'>
        <input type='text' name='name' @bind="self.name">

    <div class='form-group'>
        <input type='text' name='profession' @bind="self.name">

    <div class='form-group'>
        <select name='gender' @bind="self.gender">
            <option value="1">Male</option>
            <option value="2">Female</option>

    <div class='form-group'>
        <input type='button' value='Save profile' onClick='self.save()'>

// Apply the self object to an existing HTML element already in the DOM
let self = {};
self.name = 'John Lennon';
self.profession = 'Musician';
self.gender = 1;
self.save = function() {
    alert('Do something...');
lemonade.apply(document.getElementById('myForm'), self);


You can use lemonade.render and lemonade.element to create components, or use lemonade.apply to bind a self to a block of HTML code.
