From 8e5aa5093ab6e67db4f603a44bb7027245b91a21 Mon Sep 17 00:00:00 2001 From: Azul Date: Tue, 15 Oct 2013 14:31:52 +0200 Subject: detect os in browser and show proper download link We add a class to the html element based on the detected os and use that to pick which download link should be visible. If we detect an os that is not supported we display a deactivated download link instead with all alternatives. --- core/app/assets/javascripts/platform.js | 92 +++++++++++++++++++++++++++++++++ 1 file changed, 92 insertions(+) create mode 100644 core/app/assets/javascripts/platform.js (limited to 'core/app/assets/javascripts') diff --git a/core/app/assets/javascripts/platform.js b/core/app/assets/javascripts/platform.js new file mode 100644 index 0000000..3ab77d7 --- /dev/null +++ b/core/app/assets/javascripts/platform.js @@ -0,0 +1,92 @@ +/* Inspired by mozillas platform detection: + https://github.com/mozilla/bedrock/tree/master/media/js/base +*/ + (function () { + 'use strict'; + function getPlatform() { + var ua = navigator.userAgent, + pf = navigator.platform; + if (/Win(16|9[x58]|NT( [1234]| 5\.0| [^0-9]|[^ -]|$))/.test(ua) || + /Windows ([MC]E|9[x58]|3\.1|4\.10|NT( [1234]| 5\.0| [^0-9]|[^ ]|$))/.test(ua) || + /Windows_95/.test(ua)) { + /** + * Officially unsupported platforms are Windows 95, 98, ME, NT 4.x, 2000 + * These regular expressions match: + * - Win16 + * - Win9x + * - Win95 + * - Win98 + * - WinNT (not followed by version or followed by version <= 5) + * - Windows ME + * - Windows CE + * - Windows 9x + * - Windows 95 + * - Windows 98 + * - Windows 3.1 + * - Windows 4.10 + * - Windows NT (not followed by version or followed by version <= 5) + * - Windows_95 + */ + return 'oldwin'; + } + if (ua.indexOf("MSIE 6.0") !== -1 && + ua.indexOf("Windows NT 5.1") !== -1 && + ua.indexOf("SV1") === -1) { + // Windows XP SP1 + return 'oldwin'; + } + if (pf.indexOf("Win32") !== -1 || + pf.indexOf("Win64") !== -1) { + return 'windows'; + } + if (/android/i.test(ua)) { + return 'android'; + } + if (/armv[6-7]l/.test(pf)) { + return 'android'; + } + if (pf.indexOf("Linux") !== -1) { + if (pf.indexOf("64") !== -1) { + return 'linux64'; + } else { + return 'linux32'; + } + } + if (pf.indexOf("MacPPC") !== -1) { + return 'oldmac'; + } + if (/Mac OS X 10.[0-5]/.test(ua)) { + return 'oldmac'; + } + if (pf.indexOf('iPhone') !== -1 || + pf.indexOf('iPad') !== -1 || + pf.indexOf('iPod') !== -1 ) { + return 'ios'; + } + if (ua.indexOf("Mac OS X") !== -1) { + return 'osx'; + } + if (ua.indexOf("MSIE 5.2") !== -1) { + return 'oldmac'; + } + if (pf.indexOf("Mac") !== -1) { + return 'oldmac'; + } + if (navigator.platform === '' && + navigator.userAgent.indexOf("Firefox") !== -1 && + navigator.userAgent.indexOf("Mobile") !== -1) { + return 'fxos'; + } + + return 'other'; + } + (function () { + // Immediately set the platform classname on the html-element + // to avoid lots of flickering + var h = document.documentElement; + window.site = { + platform : getPlatform() + }; + h.className = window.site.platform; + })(); + })(); -- cgit v1.2.3
