Storage.getItem()

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

SyntaxEdit

var aValue = storage.getItem(keyName);

Parameters

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

Returns

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

ExampleEdit

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;

  htmlElem.style.backgroundColor = '#' + currentColor;
  pElem.style.fontFamily = currentFont;
  imgElem.setAttribute('src', currentImage);
}

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

All browsers have varying capacity levels for both localStorage and sessionStorage. Here is a detailed rundown of all the storage capacities for various browsers.

Note: since iOS 5.1, Safari Mobile stores localStorage data in the cache folder, which is subject to occasional clean up, at the behest of the OS, typically if space is short.
