Hướng dẫn check cookie enabled javascript

Question

Published January 27, 2021

To check whether a setting a cookie is enabled in the browser, you can use the cookieEnabled property in the window.navigator global object in JavaScript.

// check if cookie enabled in browser
const isCookieEnabled = navigator.cookieEnabled;

console.log(isCookieEnabled); // true

The property will return a Boolean true if cookie enabled and return false if not enabled.

See this example live in JSBin.

For checking cookies you can use:

function checkCookie(){
    var cookieEnabled = navigator.cookieEnabled;
    if (!cookieEnabled){ 
        document.cookie = "testcookie";
        cookieEnabled = document.cookie.indexOf("testcookie")!=-1;
    }
    return cookieEnabled || showCookieFail();
}

function showCookieFail(){
  // do something here
}


// within a window load,dom ready or something like that place your:
checkCookie();

And for checking JavaScript use a

// Example[1]: if ( hasCookies() )
/**
* @hasCookies:  Check if cookie's are Enabled
* @param  {none} ''
* @return {BOOLEAN} true|false
*/
function hasCookies() {
return (navigator.cookieEnabled);
}

 // Example[2]: if ( JLS.TEST.COOKIE() )
// Java Pattern ( How to write usable JS)
/** @namespace JLS classes and functions. */
var JLS = JLS || {};
/**
* TEST utility
* @namespace JLS
* @class TEST
*/
JLS.TEST = {

/**
* @public-method COOKIE
* @COOKIE  Check if cookie's are Enabled
* @return {BOOLEAN} true|false
*/
 COOKIE: function () {
    //Change this (library). Not main.js (Algorithm)
    return (navigator.cookieEnabled);
    }
};

This is the easiest way

if (navigator.cookieEnabled) {
  document.write("Cookies Enabled");
} else {
  document.write("Oops Cookies Not Enabled");
}

Check if Cookies Enabled in Your Browser:

This function can view error message for users and also can stop script executing and it can return cookies status.

function IS_Cookies_Enabled(Show_Message, Stop_Script)
{
    if(Show_Message == undefined){
        Show_Message = true;
    }

    if(Stop_Script == undefined){
        Stop_Script = false;
    }


    var Cookie_Status = navigator.cookieEnabled;
    if (!Cookie_Status)
    { 
        document.cookie = "Test";
        Cookie_Status = document.cookie.indexOf("Test") != -1;
        // Delete test cookies
        document.cookie = "Test=1; expires=Thu, 01-Jan-1970 00:00:01 GMT";

    }

    if((!Cookie_Status) && (Show_Message))
    {
        document.getElementsByTagName('body')[0].innerHTML = "Cookies Required
Cookies are not enabled on your browser. 
Please enable cookies in your browser preferences to continue.
Sylingo";
    }

    if((!Cookie_Status) && (Stop_Script))
    {
        throw new Error('Cookies is disabled');
    }
    return Cookie_Status;
}

To use it:

IS_Cookies_Enabled(true, true);  // Will stop script and view error message

IS_Cookies_Enabled(true, false);  // Just view error message

$Cookies_Status = IS_Cookies_Enabled(false, false);  // return cookies status

And for checking JavaScript use:

This JavaScript function has always worked for me:

if (typeof areCookiesAllowed !== 'function')
    {
        function areCookiesAllowed()
            {
                var cookies_allowed = navigator.cookieEnabled;

                if (!cookies_allowed)
                    {
                        try
                            {
                                var cur_dt = new Date();
                                var cur_tm = cur_dt.getTime();

                                document.cookie = 'cookie_test_' + cur_tm + '=1';
                                cookies_allowed = document.cookie.indexOf('cookie_test_' + cur_tm + '=') !== -1;
                                document.cookie = 'cookie_test_' + cur_tm + '=1; expires=Thu, 01-Jan-1970 00:00:01 GMT';
                            }
                        catch(err)
                            {
                                return false;
                            };
                    };

                return cookies_allowed;
            };
    };

if (typeof areCookiesAllowed !== 'function')
	{
		function areCookiesAllowed()
			{
				var cookies_allowed = navigator.cookieEnabled;

				if (!cookies_allowed)
					{
						try
							{
								var cur_dt = new Date();
								var cur_tm = cur_dt.getTime();

								document.cookie = 'cookie_test_' + cur_tm + '=1';
								cookies_allowed = document.cookie.indexOf('cookie_test_' + cur_tm + '=') !== -1;
								document.cookie = 'cookie_test_' + cur_tm + '=1; expires=Thu, 01-Jan-1970 00:00:01 GMT';
							}
						catch(err)
							{
								return false;
							};
					};

				return cookies_allowed;
			};
	};
  
var result_elmt = document.getElementById("result");
var result;

if (areCookiesAllowed() === true)
	{
		result = 'Congratulations! Cookies are enabled in this Web Browser and on this website!';
	}
else
	{
		result = 'Aww Snap! Unfortunatly cookies are NOT enabled in this Web Browser or are disabled on this website.';
	};

result_elmt.innerHTML = result;
alert(result);

Try tags it works partial to check if JavaScript is enabled or not.
