从localstorage javascript中删除价值

Question

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.

Answer 1

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.

Answer 2

不带（）的localStorage.clear当前可在主要浏览器中使用。
