I'm trying to remove item from localStorage in javasscript but it doesn't work.

It only works manually for the sequence of the following events

Right click --> Inspect element --> Resources --> localStorage --> Right click --> Delete

I tried: 

localStorage.clear();

and

localStorage.removeItem(key); // the key is the link of the page and 
                              // the value is the selected word in the page

and both didn't work, I can save item using localStorage.setItem(key, vaule) and get items from localStorage using localStorage.getItem(key) but I can't remove them.

  • this is the only thing is not working , i want to remove the old values and put another each time i use this "function" so everything is perfect unless localStorage.clear(), it won't remove anything – elianore Feb 13 '13 at 22:54

what your looking for is this:

deleter void removeItem(DOMString key);

You could implement this like so:

localStorage.removeItem(key)

Everything about local storage can be found here on the W3 html5 spec for web storage.

You may find this document more helpful as it goes into more explanation.

*Local storage is not a finished spec and these could change.

localStorage.clear without the () currently works in major browsers.

    Does it? `localStorage.clear` isn't a function call. `localStorage.clear()` **is**. And since [Clear localStorage](http://stackoverflow.com/q/7667958/691711) opts for `()`, I think that might be correct. – zero298 Mar 24 '14 at 23:55
