Answer 1

localStorage.setItem('your_data_key', 'your_data')

Answer 2

I can't see anywhere in your code where you're storing something to localStorage. You're trying to retrieve localStorage[students], but there's nothing there.

Note also that you can only store strings in localStorage. You're assigning a jQuery result to students at one point. Were you to try and store that in localStorage it would fail as it's an array of jQuery obects.

Answer 3

You are not setting the data, you are getting the data that doesn't exist

I believe what you want is this

(You have to give a name to the variable in local storage, I'm giving it the name of students)

localStorage['students'] = students;
$("#clickme").text("Students' first names: " + students);

After this you can have your get if you want similar to what you had before

var s_data = localStorage['students'];

Answer 4

You can use the setItem() to set a value to the localStorage and getItem() to retrieve it

Ex:

localStorage.setItem('mykey', 'somevalue')
