<h1>The Storage removeItem() Method</h1>
<p>This example demonstrates how to use the removeItem() method to delete a specified session storage item.</p>
<h2>Missing sessionStorage item?</h2>
<p>Since you might not have the specified item stored in your session storage, we have added a script that creates it for you.</p>
<button onclick="createItem()">Create session storage item</button>
<h2>Remove Item</h2>
<p>Click the button to delete the item:</p>
<button onclick="deleteItem()">Delete item</button>
<h2>Display Item</h2>
<p>Click the button to display the items's value:</p>
<button onclick="displayItem()">Display item</button>
<p id="demo"></p>
<script>
function createItem() {
  sessionStorage.setItem("test1", "hello");
}
function deleteItem() {
  sessionStorage.removeItem("test1");
}
function displayItem() {
  var x = sessionStorage.getItem("test1");
  document.getElementById("demo").innerHTML = x;
}
</script>
