Find out how to add functionality in your Angular 2 application that deletes data in web storage based on your user's input.
- [Instructor] We remove items from session storage…using the remove item method of the session storage…property found on the browser's window object.…Session storage is a built in browser global…and no special angular code is needed to use this feature.…In our application let's add functionality…in our user list component that removes…session storage items whenever the…clear button is pressed in our UI.…This is done by adding a reference…to the session storage property inside…our on clear method in the component.…
In our method we'll add a new line…and reference the window.sessionstorage.removeItem method.…The remove item method takes one argument,…a string, representing the key of the data…we want to remove.…In our case that key will be filter.…If we look at the application tab…in our developer tools we can peek inside…session storage and watch our key value pair…disappear when the clear button is clicked.…Since we're now referencing our storage key…in both the on filter and on clear methods…it's good practice to pull that value out…
