The getItem() method of the Storage interface, when passed a key name, will return that key's value.


var aValue = storage.getItem(keyName);


A DOMString containing the name of the key you want to retrieve the value of.


A DOMString containing the value of the key. If the key does not exist, null is returned.


The following function retrieves three data items from local storage, then uses them to set custom styles on a page.

function setStyles() {
  var currentColor = localStorage.getItem('bgcolor');
  var currentFont = localStorage.getItem('font');
  var currentImage = localStorage.getItem('image');

  document.getElementById('bgcolor').value = currentColor;
  document.getElementById('font').value = currentFont;
  document.getElementById('image').value = currentImage; = '#' + currentColor; = currentFont;
  imgElem.setAttribute('src', currentImage);

Note: To see this used within a real world example, see our Web Storage Demo.
