Bagaimana Mencari Butiran Sistem Pengendalian Menggunakan JavaScript?
JavaScript menyediakan pelbagai kaedah untuk mendapatkan maklumat tentang sistem pengendalian dan versi OS pengguna. Berikut ialah skrip komprehensif untuk mencapai ini:
(function (window) { { var unknown = '-'; // screen var screenSize = ''; if (screen.width) { width = (screen.width) ? screen.width : ''; height = (screen.height) ? screen.height : ''; screenSize += '' + width + " x " + height; } // browser var nVer = navigator.appVersion; var nAgt = navigator.userAgent; var browser = navigator.appName; var version = '' + parseFloat(nVer); var nameOffset, verOffset, ix; // Yandex Browser if ((verOffset = nAgt.indexOf('YaBrowser')) != -1) { browser = 'Yandex'; version = nAgt.substring(verOffset + 10); } // Samsung Browser else if ((verOffset = nAgt.indexOf('SamsungBrowser')) != -1) { browser = 'Samsung'; version = nAgt.substring(verOffset + 15); } // UC Browser else if ((verOffset = nAgt.indexOf('UCBrowser')) != -1) { browser = 'UC Browser'; version = nAgt.substring(verOffset + 10); } // Opera Next else if ((verOffset = nAgt.indexOf('OPR')) != -1) { browser = 'Opera'; version = nAgt.substring(verOffset + 4); } // Opera else if ((verOffset = nAgt.indexOf('Opera')) != -1) { browser = 'Opera'; version = nAgt.substring(verOffset + 6); if ((verOffset = nAgt.indexOf('Version')) != -1) { version = nAgt.substring(verOffset + 8); } } // Legacy Edge else if ((verOffset = nAgt.indexOf('Edge')) != -1) { browser = 'Microsoft Legacy Edge'; version = nAgt.substring(verOffset + 5); } // Edge (Chromium) else if ((verOffset = nAgt.indexOf('Edg')) != -1) { browser = 'Microsoft Edge'; version = nAgt.substring(verOffset + 4); } // MSIE else if ((verOffset = nAgt.indexOf('MSIE')) != -1) { browser = 'Microsoft Internet Explorer'; version = nAgt.substring(verOffset + 5); } // Chrome else if ((verOffset = nAgt.indexOf('Chrome')) != -1) { browser = 'Chrome'; version = nAgt.substring(verOffset + 7); } // Safari else if ((verOffset = nAgt.indexOf('Safari')) != -1) { browser = 'Safari'; version = nAgt.substring(verOffset + 7); if ((verOffset = nAgt.indexOf('Version')) != -1) { version = nAgt.substring(verOffset + 8); } } // Firefox else if ((verOffset = nAgt.indexOf('Firefox')) != -1) { browser = 'Firefox'; version = nAgt.substring(verOffset + 8); } // MSIE 11+ else if (nAgt.indexOf('Trident/') != -1) { browser = 'Microsoft Internet Explorer'; version = nAgt.substring(nAgt.indexOf('rv:') + 3); } // Other browsers else if ((nameOffset = nAgt.lastIndexOf(' ') + 1) < (verOffset = nAgt.lastIndexOf('/'))) { browser = nAgt.substring(nameOffset, verOffset); version = nAgt.substring(verOffset + 1); if (browser.toLowerCase() == browser.toUpperCase()) { browser = navigator.appName; } } // trim the version string if ((ix = version.indexOf(';')) != -1) version = version.substring(0, ix); if ((ix = version.indexOf(' ')) != -1) version = version.substring(0, ix); if ((ix = version.indexOf(')')) != -1) version = version.substring(0, ix); majorVersion = parseInt('' + version, 10); if (isNaN(majorVersion)) { version = '' + parseFloat(nVer); majorVersion = parseInt(nVer, 10); } // mobile version var mobile = /Mobile|mini|Fennec|Android|iP(ad|od|hone)/.test(nVer); // cookie var cookieEnabled = (navigator.cookieEnabled) ? true : false; if (typeof navigator.cookieEnabled == 'undefined' && !cookieEnabled) { document.cookie = 'testcookie'; cookieEnabled = (document.cookie.indexOf('testcookie') != -1) ? true : false; } // system var os = unknown; var clientStrings = [ {s:'Windows 10', r:/(Windows 10.0|Windows NT 10.0)/}, {s:'Windows 8.1', r:/(Windows 8.1|Windows NT 6.3)/}, {s:'Windows 8', r:/(Windows 8|Windows NT 6.2)/}, {s:'Windows 7', r:/(Windows 7|Windows NT 6.1)/},
