Delete Array From Object In Localstorage

When I click on a button I load the function 'DeleteFromlocalStorage' with the parameter 'id'. This is my function 'DeleteFromlocalStorage': function DeleteSessionFromLocal

Solution 1:

I may be wrong but here is what you want to do:

Either localStorage.removeItem(key);

Or if ifs something within the localStorage JSON item then do:

functionDeleteSessionFromLocalStorage(data)
{
    var id_session = data;
    //Not sure but you might need to do JSON.parse(a) after to get it
    a = localStorage.getItem('session');

    delete a.dataalert(a);

}

Solution 2:

Your code sample just looks like a javascript object to me. In which case you can use the 'delete' keyword. Good discussion here:

How do I remove a property from a JavaScript object?

So something like

delete a["21114"]

Solution 3:

for(obj in json) {       
            if(json[obj].id == id_session)
            {
                delete json[obj];

            }
        }

        localStorage.setItem('session', JSON.stringify(json));

Get the objects, check every id of every object and delete the ones with the id = "id_session".
