Hi,

SetItem() and getItem() work with the following code, but not removeItem(). Do I need to format the object before removing it? Code below. Cheers.

<!DOCTYPE HTML>
<html>
<body>

<script>

function storeusername()
{
	var person = {};
	person.age = 25;
	person.firstname = 'Joe';
	person.lastname = 'Smith';
	localStorage.setItem('persondetails', JSON.stringify(person));
}

function getusername()
{
	var person = JSON.parse(localStorage.getItem('persondetails'));
	document.getElementById('username').innerHTML = person.age + ' ' + person.firstname + ' ' + person.lastname;
}

function clearusername()
{
	localstorage.removeItem('personaldetails');
}

</script>
<br/>
Name: <p id="username"></p>
<input type=button value="Store" onclick="storeusername()" />
<input type=button value="Retrieve" onclick="getusername()" />
<input type=button value="Clear" onclick="clearusername()" />
</body>
</html>

removeItem is correct, but you have to specify the right key. To add stuff you use persondetails and to remove you use personaldetails, so that's not going to work.

JavaScript

// localStorage is with capital S (very important, localstorage is undefined).
// The key is persondetails, and not personaldetails.
localStorage.removeItem('persondetails');
