Learn how
you can implement the local storage using Google web tool kit.
Local
storage helps you to keep the data on client machine or end user machine but never use an important data on local storage because local storage is not a secure storage.
Creating an
instance using Storage class and also checking whether the browser supports local storage
or not using getLocalStorageIfSupported() method.
Storage
stockStore = Storage.getLocalStorageIfSupported();
Insert the
data using setItem() method , fetch data using getItem() method and clear the local
storage data using clear() method.
stockStore.setItem(String
key, String data);
stockStore.getItem(String
key);
stockStore.clear();}
Set Item has
two parameters, one is key and another one is data. Key is used to maintain the
index and data is the parameter where we can save the string which is needed in
other place.
Example :-
stockStore.setItem(“userName”,”demo”);
stockStore.setItem(“companyName”,
“company”);
Get Item has
only one parameter i.e., key , so enter the key to get a particular value.
Example:-
stockStore.getItem(“userName”);
// retrieve demo
stockStore.getItem(“companyName”);
// retrieve company
