How to delete a cookie?
cookies, javascript
Solution
Try this:
function delete_cookie( name, path, domain ) {
if( get_cookie( name ) ) {
document.cookie = name + "=" +
((path) ? ";path="+path:"")+
((domain)?";domain="+domain:"") +
";expires=Thu, 01 Jan 1970 00:00:01 GMT";
}
}
You can define `get_cookie()` like this:
function get_cookie(name){
return document.cookie.split(';').some(c => {
return c.trim().startsWith(name + '=');
});
}
Problem
Is my function of creating a cookie correct? How do I delete the cookie at the beginning of my program? is there a simple coding? ``` function createCookie(name,value,days) ``` ``` function setCookie(c_name,value,1) { document.cookie = c_name + "=" +escape(value); } setCookie('cookie_name',mac); function eraseCookie(c_name) { createCookie(cookie_name,"",-1); } ```
