Removing items from the localStorage

Question

I\'m trying to remove the individual items from the localStorage. I\'m using localStorage for storing selected list items in the listview. I attached the checkboxes for remo

Answer 1

try removing items like this, removing local storage items by their key values

//syntax is localStorage.removeItem('keyName');
//so if your key name is checked                  
localStorage.removeItem('checked');

See this Link for reading about local storage.

Answer 2

Just use localStorage.clear();

Answer 3

localstorage.removeItem() wont work as expected. I had faced the same problem while trying to handle the localstorage items.

A work-around for this problem was to set the local storage item to null. It served my purpose.

For example if you have a localStorage item named test then to clear the item use :

localStorage.setItem("test", "");

Although this may not be the correct way, i had gone bonkers over this issue and the above one served my purpose.

Answer 4

I think the problem is in this part:

$("#delete").on('click', function() {
            var checked = $('#add #check:checkbox:checked');
            var url = localStorage.key(checked);
            localStorage.removeItem(url);
            $("#favoritesList").listview('refresh');
});

you are not using correct key for deleting and its because you are using :

var url = localStorage.key(checked);

and checked==[Object]==1 so you are pointing to localStorage.key(1)

for solving this problem you can both use key=localStorage.key(some);localStorage.removeItem(key); and localStorage.removeItem(some); but the important part is that you should match 'an index(first way)' or a 'key value(the second way)' for each checkbox and I can help you if I have the complete code (I think still there are some part of HTML or codes that are related)(also it would be so good if you put a fiddle of your codes)
