Cookie not being deleted after session closed

I'm using cookies that should be deleted after user closes the page, but they're not. This is how I set cookies with JS

document.cookie="status=false";

I can see the cookie in console and after I close browser and open it again and go to my webpage there's still cookie status=false any idea why?

I solved it with this "trick", I don't know why I can't get cookies to work 

window.onbeforeunload = function() {
    document.cookie="status=false";
};

I was actually doing this today. A great reference is the Mozilla cookie documents if you create a js with their var docCookies code then using the functions provided like docCookies.setItem() docCookies.setItem() docCookies.getItem() or docCookies.removeItem() work incredible well.

document.cookie = ... sets individual cookie values, it does not set "the entire cookie" to the string you passed, so setting "status=false" simply binds or updates the "status" value, irrespective of whatever else is in the cookie:

document.cookie = "cow=bell";
document.cookie = "cat=lol";
// cookie is now "cow=bell&cat=lol", not just "cat=lol"

If you want to delete the entire cookie, set its expiration time to "in the past" and the browser will do the cleanup for you.

(As pointed out in a comment, if you never set an expiration timestamp for your cookie, it'l expire when the page session ends, e.g. you close the tab/browser)
