Question

I have a webapp where my employees take quizes(Multiple choice question) .I have to save user response in json format and submit the response to server when user hits the submit button but When a person is going through a quiz and suddenly its system crashes or shutdown due to some reason I want to be able to save the progress of user locally.What I want is to store that json data locally till the time user submits the quiz and once user hits the submit button the local data should be destroyed.So that in case if system crashes I can collect the user progress from participant system manually.So is thr any way to store data locally using javascript?

You can use local storage from HTML5

localStorage.setItem(id, value);

To retrieve the storage value use:

localStorage.getItem(id);
