disable third party cookies using javascript

问题

i am working to implement the new cookie policy compliance as per data protection rules for all companies operating in the EU. According to which user has to be able to refuse/accept all but required cookies when he is using any website. In my client's website i can see the following third party cookies are getting stored.

_ga - my-site
_gid - my-site
__ncuid - .doubleclick.net
DSID - .doubleclick.net
IDE - .doubleclick.net
1P_JAR - .google.be
NID - .google.be
CONSENT -.google.be
NID - .google.com
AID - .google.com
CONSENT - .google.com
1P_JAR - .google.com
DV - www.google.be
OTZ - www.google.com
locale - my-site
anonymousUserId - my-site
SESSID - my-site
JSESSIONID - my-site
TS01c70fa1 - my-site

in the above mentioned list few cookies are google analytics cookies intiated by google tag manager. I have handled them. but all the cookies with domain 'google' and '.doubleclick.net' i have no control over them? and i am not able to understand how are they getting stored.

can anyone help me, or suggest me if there is anyway to disable these cookies on user consent using javascript? Thanks in advanced.

回答1:

Instead of blocking cookies that are being/were set, it's easier to not load i.e. the GTM script until after the user has consented to the cookie policy.

回答2:

To block third-party cookies, find a JavaScript code that is setting third-party cookies and:

change type attribute from text/javascript to text/plain (if type attribute missing, just add it)
add data-cookiescript attribute and set it to accepted

All JavaScript with such attribute changes will only execute if user agreed with Cookie Policy.

Hope this helps !!

To disable _ga and _gid cookies do add the following code on your headers.php:

<script>
    if(document.cookie.split('; ').findIndex(x => x.split('=')[0] == 'cookiename') >= 0) 
    {
        // some code
    } else {
        window["ga-disable-UA-7358061-1"] = true;
        window["gid-disable-UA-7358061-1"] = true;
    }
</script>

A little bit old but I think you deserve a answer that works:

Step 1: Like thomaux already wrote: Don't load/execute the script. You can provide the code with the trick from vizsatiz without executing but add an id to the html element like GA_SCRIPT.

Step 2: Show the cookie banner.

Step 3: After the user accepted, load the code from the html element with document.getElementById("GA_Script").innerText and execute with eval.

Worked for me.

Alternatively you could write the GA script code into your code and execute it as a callback.
