How to find the operating system version using Jav

2楼-- · 2018-12-31 07:32

I fork @Ludwig code and remove necessity of swfobject.

I just use swfobject code for detect flash version.

/**

(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(navigator.appVersion);
    var majorVersion = parseInt(navigator.appVersion, 10);
    var nameOffset, verOffset, ix;

    // Opera
    if ((verOffset = nAgt.indexOf('Opera')) != -1) {
        browser = 'Opera';
        version = nAgt.substring(verOffset + 6);
        if ((verOffset = nAgt.indexOf('Version')) != -1) {
        version = nAgt.substring(verOffset + 8);
        }
    }
    // 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);

        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

I started to write a Script to read OS and browser version that can be tested on Fiddle. Feel free to use and extend.

@Ludwig 's solution was brilliant. A couple of fixes (which didn't have to do with operating system, and I couldn't place as a comment on his original posting because this is too long):

IE 11 no longer identifies itself as MS IE.
Chrome on IOS spoofs itself as Safari

Here they are:

(function (window) {
    {
    /* test cases
        alert(
            'browserInfo result: OS: ' + browserInfo.os +' '+ browserInfo.osVersion + '\n'+
                'Browser: ' + browserInfo.browser +' '+ browserInfo.browserVersion + '\n' +
                'Mobile: ' + browserInfo.mobile + '\n' +
                'Cookies: ' + browserInfo.cookies + '\n' +
                'Screen Size: ' + browserInfo.screen
        );
    */
        var unknown = '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(navigator.appVersion);
        var majorVersion = parseInt(navigator.appVersion, 10);
        var nameOffset, verOffset, ix;

        // Opera
        if ((verOffset = nAgt.indexOf('Opera')) != -1) {
            browser = 'Opera';
            version = nAgt.substring(verOffset + 6);
            if ((verOffset = nAgt.indexOf('Version')) != -1) {
                version = nAgt.substring(verOffset + 8);
            }
        }
        // MSIE
        else if ((verOffset = nAgt.indexOf('MSIE')) != -1) {
            browser = 'Microsoft Internet Explorer';
            version = nAgt.substring(verOffset + 5);
        }

        //IE 11 no longer identifies itself as MS IE, so trap it

You can find the OS name and version in the navigator object, as others have answered. The standard, cross-browser place to find this information is in the navigator.userAgent property. However, user agent strings vary widely by OS and browser.

So, I created a script to encapsulate this logic and report on the most common OSes and browsers in a familiar way, like http://www.whatsmybrowser.org.

I open-sourced the script and uploaded it to github, https://github.com/keithws/browser-report. Pull requests are welcome!

I can't comment on @Ian Ippolito answer (because I would have if I had the rep) but according to the document his comment linked, I'm fairly certain you can find the Chrome version for IOS. https://developer.chrome.com/multidevice/user-agent?hl=ja lists the UA as: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1

So this should work:

if ((verOffset = nAgt.indexOf('CriOS')) != -1) {
                //Chrome on iPad spoofing Safari...correct it.
                browser = 'Chrome';
                version = nAgt.substring(verOffset + 6);//should get the criOS ver.
            }

Haven't been able to test (otherwise I would have improved his answer) it to make sure since my iPad is at home and I'm at work, but I thought I'd put it out there.
