arrow-buttons

This module builds "next" and "previous" buttons and emits an update whenever the index changes. If the index changes outside of this module, it is important to notify this module of the new index.

ES5 polyfills needed for Array.forEach.

To get started

CommonJS

$ npm install c2-arrow-buttons

var ArrowButtons = require('c2-arrow-buttons');

Browser Global

<script src="https://code.jquery.com/jquery-3.0.0.min.js"></script>
<script src="TheC2Group/event-handler.js"></script>
<script src="standalone/arrow-buttons.js"></script>

Basic example

// The max is typically the array length minus 1
var max = 5;

// This wouldn't be necessary since all these options are the defaults
var options = {
    previousHTML: '<a href="#" class="previous"><span class="Hidden">Go to previous item</span></a>',
    nextHTML: '<a href="#" class="next"><span class="Hidden">Go to next item</span></a>',
    style: 'finite', // 'finite' || 'infinite'
    attribute: 'data-status',
    enabled: 'enabled',
    disabled: 'disabled',
    initial: 0
};

var arrows = new ArrowButtons('#parent', max, options);

arrows.on('update', function (index) {
    console.log(index);
});
