jQuery Cloner

A jQuery plugin to clone HTML content

Getting Started

This guide will help you install and use jQuery Cloner. See deployment for notes on how to deploy this plugin on frontend development on a live website.

Installation

via bower:

bower install jquery-cloner

via npm:

npm install jquery-cloner

or download or clone (pun!) on GitHub.

Usage

jQuery Cloner relies on classes and attributes to work.

A simple sample markup:

<!-- initialize jQuery-Cloner via the `data-toggle=cloner` attribute -->
<div class="clonable-block" data-toggle="cloner">
    <div class="clonable" data-clone-number="1">
        <label for="attr_1" class="clonable-increment-for">Attribute <span class="clonable-increment-html">1</span></label>
		<input id="attr_1" class="clonable-increment-id clonable-increment-name" type="text" name="attr[0]">
		<button type="button" class="clonable-button-close">Delete</button>
    </div>
    <button class="clonable-button-add" type="button">Add Attributes</button>
</div>

<!-- jQuery is, of course, a dependency -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<!-- Our main man here -->
<script src="jquery-cloner/dist/jquery-cloner.min.js"></script>

In the example above, the data-toggle="cloner" will automatically initialize our HTML.

Manual initialization, then, is as easy as:

// main.js
(function ($) {
    $('#my-clonable-block').cloner();
})(jQuery);

Options

The plugin have options you can modify. Below is the list of options with their default values:

$('#my-clonable-block').cloner({
    clonableContainer: '.clonable-block',
    clonable: '.clonable',
    addButton: '.clonable-button-add',
    closeButton: '.clonable-button-close',
    focusableElement: ':input:visible:enabled:first',

    clearValueOnClone: true,
    removeNestedClonablesOnClone: true,
    limitCloneNumbers: true,

    debug: false,

    cloneName: 'clonable-clone',
    sourceName: 'clonable-source',

    incrementName: 'clonable-increment',
    decrementName: 'clonable-decrement',
});

clonableContainer - The class that should contain all our clonable elements, including the Add Button

clonable - The class of the clonable element. This is the html chunk that will be repeated.

addButton - The class of the button that will fire the toggle method, prompting the cloning action.

closeButton - The class of the button that will fire the remove method, prompting to remove the clonable element. Important: this element should be inside a clonable element.

focusableElement - The attribute or input tag inside a newly cloned clonable to place the cursor over.

clearValueOnClone - The plugin will clone the last instance of the clonable class. This option will toggle to remove or retain all previous input values.

removeNestedClonablesOnClone - Toggle to remove all clone instances of the clonableContainer.

limitCloneNumbers - Will only work for decrementing clonables.

debug - Switch console.logging on/off.

incrementName - this option will increment all values inside a clonable. It uses suffixes (html, value, and any attribute like class, id, etc.) to know which integers will be incremented. Take the below as an example:

<input id="attr_1" class="clonable-increment-id clonable-increment-name" type="text" name="attr[0]">

In this example, we have classes of clonable-increments with suffixes -id and -name which corresponds with the input tag's id=attr_1 and name="attr[0]". Performing a clone, therefore will result in

<input id="attr_1" class="clonable-increment-id clonable-increment-name" type="text" name="attr[0]">
<input id="attr_2" class="clonable-increment-id clonable-increment-name" type="text" name="attr[1]">

It does this using regex.

decrementName - The reverse of increment.

beforeToggle - this is a function callback you can hook into before the cloning action is fired. It accepts parameters $clone( the clone of the last clonable), index (the clonables' length), and self (a catch-all reference of the jQuery-Cloner itself). An example use case:

$('#my-clonable-block').cloner({
    beforeToggle: function ($clone, i, self) {
        // console.log(self);
		var $container = self.$container;
		if ($clone.find('input:last').val() == "") {
		    $container.css({border:'1px solid red'});
		} else {
			$container.css({border:'none'});
		}
    },
});

afterToggle - this will fire after the cloning action is triggered.
