Getting ready

First, we create an empty project with VS 2017, and use JavaScript code to store data.

We need as a minimum browser requirement IE8, Firefox 3.5, or Chrome 4.0 to benefit from HTML5 capabilities in the browser.

All the following methods and properties are available for both localStorage and seesionStorage:

  • getItem(key): Store a key/value pair
  • setItem(key, value): Return a value associated with a key
  • removeItem(key): Delete a key/value pair with a key
  • clear(): Delete all key/value pairs
  • length: Return the number of stored pairs
