How to Check User Browser is Supported or Not in jQuery

WebSolutionStuff | Nov-13-2020 | Categories : Laravel PHP jQuery Bootstrap

In this article, we will see how to check user browser is supported or not in jquery. Some time latest features are not supported in many browsers like internet explorer, safari, google chrome, etc. So, in this post, we will show you how to detect the user browser. We will get user agents of chrome, safari, and internet explorer using javascript.

So, let's see detect the browser using jquery, and check if the browser supports javascript.

Detect Chrome browser

indexOf() method is used to return the first occurrence of the specified string value in a string. If the value does not come up in the string, “-1” is returned.

let chromeAgent = userAgentString.indexOf("Chrome") > -1;

Detect Internet Explorer browser

The userAgent of the Internet Explorer browser is “MSIE” or “rv:”. these values are passed in the indexOf() method to detect this value in the userAgentString and the result of both them are used with the OR operator.

let IExplorerAgent = userAgentString.indexOf("MSIE") > -1 ||  
                     userAgentString.indexOf("rv:") > -1;

Detect Firefox browser

The user-agent of the Firefox browser is “Firefox”. This value is passed to the indexOf() method to detect this value in the user-agent string.

let firefoxAgent = userAgentString.indexOf("Firefox") > -1;

Detect Safari browser

The user-agent of the Safari browser is “Safari”. This value is passed to the indexOf() method to detect this value in the user-agent string.

One additional check is required in the case of the Safari browser as the user-agent of the Chrome browser also includes the Safari browser’s user-agent. If both the user-agents of Chrome and Safari are in the user-agent, it means that the browser is Chrome, and hence the Safari browser value is discarded.

// Detect Safari 
let safariAgent = userAgentString.indexOf("Safari") > -1; 
  
// Discard Safari since it also matches Chrome 
if ((chromeAgent) && (safariAgent)) safariAgent = false;

Detect Opera browser

The user-agent of the Opera browser is “OP”. This value is passed to the indexOf() method to detect this value in the user-agent string.

One additional check is also required in the case of this browser as the user-agent of the Opera browser also includes the Chrome browser’s user-agent. If both the user-agents of Chrome and Opera are in the user-agent, it means that the browser is Opera, and hence the Chrome browser value is discarded.

// Detect Opera 
let operaAgent = userAgentString.indexOf("OP") > -1; 
  
// Discard Chrome since it also matches Opera         
if ((chromeAgent) && (operaAgent)) chromeAgent = false;
