How to retrieve all localStorage items without knowing the keys in advance?

Question

I want to show all of the keys and storage written before. My code is below. I created a function (allStorage) but it doesn\'t work. How can I do this?

Answer 1

// iterate localStorage
for (var i = 0; i < localStorage.length; i++) {

  // set iteration key name
  var key = localStorage.key(i);

  // use key name to retrieve the corresponding value
  var value = localStorage.getItem(key);

  // console.log the iteration key and value
  console.log('Key: ' + key + ', Value: ' + value);  

}
