Detect Safari using jQuery
JavascriptJqueryBrowser DetectionJavascript Problem Overview
Though both are Webkit based browsers, Safari urlencodes quotation marks in the URL while Chrome does not.
Therefore I need to distinguish between these two in JS.
jQuery's browser detection docs mark "safari" as deprecated.
Is there a better method or do I just stick with the deprecated value for now?
Javascript Solutions
Solution 1 - Javascript
Using a mix of feature detection and Useragent string:
var is_opera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
var is_Edge = navigator.userAgent.indexOf("Edge") > -1;
var is_chrome = !!window.chrome && !is_opera && !is_Edge;
var is_explorer= typeof document !== 'undefined' && !!document.documentMode && !is_Edge;
var is_firefox = typeof window.InstallTrigger !== 'undefined';
var is_safari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);
Usage:
if (is_safari) alert('Safari');
Or for Safari only, use this :
if ( /^((?!chrome|android).)*safari/i.test(navigator.userAgent)) {alert('Its Safari');}
Solution 2 - Javascript
The following identifies Safari 3.0+ and distinguishes it from Chrome:
isSafari = !!navigator.userAgent.match(/Version\/[\d\.]+.*Safari/)
Solution 3 - Javascript
unfortunately the above examples will also detect android's default browser as Safari, which it is not.
I used
navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1 && navigator.userAgent.indexOf('Android') == -1
Solution 4 - Javascript
For checking Safari I used this:
$.browser.safari = ($.browser.webkit && !(/chrome/.test(navigator.userAgent.toLowerCase())));
if ($.browser.safari) {
alert('this is safari');
}
It works correctly.
Solution 5 - Javascript
Apparently the only reliable and accepted solution would be to do feature detection like this:
browser_treats_urls_like_safari_does = false;
var last_location_hash = location.hash;
location.hash = '"blah"';
if (location.hash == '#%22blah%22')
browser_treats_urls_like_safari_does = true;
location.hash = last_location_hash;
Solution 6 - Javascript
The only way I found is check if navigator.userAgent contains iPhone or iPad word
if (navigator.userAgent.toLowerCase().match(/(ipad|iphone)/)) {
//is safari
}
Solution 7 - Javascript
If you are checking the browser use $.browser. But if you are checking feature support (recommended) then use $.support.
You should NOT use $.browser to enable/disable features on the page. Reason being its not dependable and generally just not recommended.
If you need feature support then I recommend modernizr.
Solution 8 - Javascript
//Check if Safari
function isSafari() {
return /^((?!chrome).)*safari/i.test(navigator.userAgent);
}
//Check if MAC
if(navigator.userAgent.indexOf('Mac')>1){
alert(isSafari());
}
Solution 9 - Javascript
This will determine whether the browser is Safari or not.
if(navigator.userAgent.indexOf('Safari') !=-1 && navigator.userAgent.indexOf('Chrome') == -1)
{
alert(its safari);
}else {
alert('its not safari');
}

I use to detect Apple browser engine, this simple JavaScript condition:
navigator.vendor.startsWith('Apple')
Solution 11 - Javascript
Generic FUNCTION
var getBrowseActive = function (browserName) {
return navigator.userAgent.indexOf(browserName) > -1;
};
Solution 12 - Javascript
A very useful way to fix this is to detect the browsers webkit version and check if it is at least the one we need, else do something else.
Using jQuery it goes like this:
"use strict";
$(document).ready(function() {
var appVersion = navigator.appVersion;
var webkitVersion_positionStart = appVersion.indexOf("AppleWebKit/") + 12;
var webkitVersion_positionEnd = webkitVersion_positionStart + 3;
var webkitVersion = appVersion.slice(webkitVersion_positionStart, webkitVersion_positionEnd);
console.log(webkitVersion);
if (webkitVersion < 537) {
console.log("webkit outdated.");
} else {
console.log("webkit ok.");
};
});
This provides a safe and permanent fix for dealing with problems with browser's different webkit implementations.
Happy coding!

// Safari uses pre-calculated pixels, so use this feature to detect Safari
var canva = document.createElement('canvas');
var ctx = canva.getContext("2d");
var img = ctx.getImageData(0, 0, 1, 1);
var pix = img.data; // byte array, rgba
var isSafari = (pix[3] != 0); // alpha in Safari is not zero

My best solution
function getBrowserInfo() {
const ua = navigator.userAgent; let tem;
let M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
if (/trident/i.test(M[1])) {
tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
return { name: 'IE ', version: (tem[1] || '') };
}
if (M[1] === 'Chrome') {
tem = ua.match(/\bOPR\/(\d+)/);
if (tem != null) {
return { name: 'Opera', version: tem[1] };
}
}
M = M[2] ? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?'];
tem = ua.match(/version\/(\d+)/i);
if (tem != null) {
M.splice(1, 1, tem[1]);
}
return {
name: M[0],
version: M[1],
};
}
getBrowserInfo();
