range-touch

range-touch =========== Lets you use **HTML5 range** input on **touch** devices <br /> (iPhone, iPad & Android) with a *single* **2kb** JS file (*no bloatware*)! ## Try it: https://range-touch.herokuapp.com ## Requirements 1. Let touch devices interact with the **<input type="range">** element 2. Do not *force* people to use any *extra* styles or script. 3. Do not modify markup on the page (other scripts do wierd things!) 4. Degrade gracefully for people with JavaScript disabled (desktop only) 5. Works with [JQuery](http://code.jquery.com/jquery-1.10.2.min.js) [**96kb**] ***or*** [Zepto](http://zeptojs.com/zepto.min.js) [**26kb**] ## Results #### iPhone (Safari Mobile iOS 7) !["range-touch iPhone"](http://i.imgur.com/hpkWznf.jpg) #### Android (Samsung Galaxy S3 - Default Browser 4.2) !["range-touch Android"](http://i.imgur.com/ZraQBwG.png) #### iPad (Safari Mobile iOS 7) !["range-touch iPad"](http://i.imgur.com/Y20bJN6.jpg) - - - ## Background Today I had to add a range ("slider") to our (HTML5) iPad App. <br /> Unfortunately, at the time of writing, *Mobile* Safari ***[does not support](http://caniuse.com/#feat=input-range)*** (touch/drag) `<input type="range">` ... so I had to search. ### Why Not Use JQuery UI...? A (*non-technical*) person in the office *asked* (in *patronizing* tone): > "*Why don't you just use Jquery UI Slider...?*" > http://jqueryui.com/slider/ Our project does *not* include JQuery UI I was *reluctant* to add it *just* for the slider feature. <br /> [jquery-ui-1.10.3.js](http://code.jquery.com/ui/1.10.3/jquery-ui.js) is **436kb**!! Even the ***minified*** version [jquery-ui.min.js](http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js) is a whopping **228kb** and you *also* need the CSS file (another **32kb**): [jquery-ui.css](http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css) (So unless you need *several* of Jquery UI's features, loading **260kb** on a mobile device is going to be *painfully slow*!) <br /> I tried building a *custom* JQuery UI script with just the *bare essentials*: <br /> http://jqueryui.com/download/ but this was *still* **140kb**+! ## Research My first search for a solution took me to **StackOverflow**: - http://stackoverflow.com/questions/5484540/recreating-the-html5-range-input-for-mobile-safari-webkit - http://stackoverflow.com/questions/16732569/zepto-js-tap-event-doesnt-fire - http://stackoverflow.com/questions/3556157/how-to-customize-the-html5-input-range-type-looks-using-css - http://stackoverflow.com/questions/5165287/how-to-achive-background-color-in-html5-inputtype-range But none of the answers solved the problem *satisfactorily*. All of them require a CSS file which overrides styles we have in our project! We need a lightweight solution that ***only*** adds touch support and no styles! ### Alternatives - JQuery Mobile: http://view.jquerymobile.com/1.3.2/dist/demos/widgets/sliders/ + http://jquerymobile.com/download-builder/ [still *huge*!] - TouchPunch [**Requires JQuery UI**!!]: http://touchpunch.furf.com/ + https://github.com/furf/jquery-ui-touch-punch - fd-slider [*bloated*!] https://github.com/freqdec/fd-slider - noUiSlider [**38kb**]: http://refreshless.com/nouislider/ + https://github.com/leongersen/noUiSlider - Jquery Tools: https://github.com/jquerytools/jquerytools - Range Polyfill: https://github.com/jonstipe/range-polyfill - Modernizr: https://github.com/Modernizr/Modernizr/ ### Bibliography - Intro to <input type="range">: http://www.html5tutorial.info/html5-range.php - Quirksmode Confirms Not Currently Supported in Safari Mobile: http://www.quirksmode.org/html5/inputs_mobile.html - http://www.developerdrive.com/2013/09/how-to-style-range-sliders-in-webkit/ - http://fusiongrokker.com/post/using-the-zepto-js-touch-events-plugin-for-more-responsive-phonegap-apps-without-zepto - http://stackoverflow.com/questions/18389224/how-to-style-html5-range-input-to-have-different-color-before-and-after-slider <br /> # License: MIT This code is licensed under MIT see: https://opensource.org/licenses/MIT Copyright (c) 2013 - 2016 dwyl.io Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
