deleting cookies with a different option, doesn't work

[bruzie]

I can confirm a variation on this bug.

If I create a cookie with the following options:

$.cookie('cookie_name','cookie_val',{expires:365,path:'/'});

I can delete the cookie with:

$.cookie('cookie_name',null)

if the page is at the root level of the site.

If the page is in a sub folder, the cookie is not deleted with the above code, but will delete if I add the {expires:365,path:'/'} option.

I am having the same issue as Bruzie.

$.cookie( 'cookie_name', null , { expire: 7, path:'/'} );

using the following seems to work no matter what the path. This isn't reflected in the documentation.

$.cookie( 'cookie_name', null , {path:'/'} );

I think I'm having a related issue:

I need to delete a cookie that's set by the server, and the domain name is variable depending on the installation. I can't seem to delete the cookie unless I define the domain, so we've had to hard code it for every installation.

I'd like to be able to do this:
$.cookie( 'cookie_name', null );

or even this:
$.cookie( 'cookie_name', null, {path:'/'} );

but only this works:
$.cookie("ESID", null, { path: '/', domain: 'ourcompany.com' });

note: HttpOnly is not set on the cookie, so that's not the issue. :)

thanks!

@scowles4 instead of hard coding the url you could get it dynamically.

Hope this helps.

@night815 Thank you for the suggestion.

I did play around with window.location.hostname to retrieve the domain but it picks up the subdomain as well (it returns dev.ourcompany.com when the cookie is set to ourcompany.com). The regex solution for this would trip on a cookie set to ourcompany.com.uk, for example. So it's safer to hard code the value and that's ok for the short term.

I'm editing my comment to say I'm going to work on syncing up with our own server-side logic to make sure the domain matches, that's more appropriate for my situation. :)

Thanks again - appreciate the help!

I think the problem is you have to know the exact path when deleting a cookie. I've had this issue with PHP many times.

I will have to test this when I get some time. If i figure out a way to do it i will submit the code to this project.

@kirkhelek

"so, if i want to delete a cookie using your plugin I need to put the same options that I used for its creation, really?"

Yes, when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie (but not expires). That's how it works in a browser. I've updated the documentation to be more clear on this.

This will become a bit more straight forward with default options.

@bruzie In your case you can delete the cookie set with path: '/' at the root level that way because root is '/'.
