The value actually appears in the div but your form submits immediately. One way to get away is to not use submit button. Change input[type=submit] to button[type=button].

This will prevent the form from being submitted.

function showDiv() {
  document.getElementById('hello').style.display = "block";
}

function showValue() {
  var name = document.getElementById('name').value;
  document.getElementById('ans').innerHTML = name;
  document.getElementById('hello').style.display = "none";
}

<input type="button" onclick="showDiv()" value="click on me" />
<form id="hello" style="display:none;">
  <label>Enter Name: </label><br>
  <input type="text" id="name" required>
  <button type="button" onclick="showValue()">submit</button>
</form>
<div id="ans"></div>
