How to clear localStorage? (JavaScript/jQuery)

Question

I'm currently testing on my local machine so the URL is as following when the user presses Sign out

// The ********** is my site name, which i don't want releasing yet http://localhost:8080/**********/logout/

Local storage item:

Key: tkn Value: EE8D9DA0F1D71A0BE8B80F3BA80343555655871151tk16

the following tests i've tried:

if (localStorage.getItem('tkn')) { localStorage.clear(); } if (localStorage.getItem('tkn')) { localStorage.removeItem('tkn'); } // I've also ran these both tests in the console of the browser // and they return back 'undefined' but the item is cleared.

However when I sign out, the user session is removed completely fine. However the localStorage doesn't seem to be cleared.

Could someone shred some light on this for me?

Instead of checking a specific property, check the length

if (localStorage.length > 0 ) { localStorage.clear(); }

localStorage is an implementation of Storage interface and Storage has a property called length

Storage.length

Returns an integer representing the number of data items stored in the Storage object.

@charlietfl In that case, specific items should be checked. But here OP has specifically asked how to clear localstorage
