<form id="greeting">
<input name="firstName" id="firstName" required="" placeholder="Your first name" type="text"><br>
<input value="Send" type="submit">
</form>
<h2 id="instruction">Now <span class="userName"></span>, I want you to walk 10 steps away from where you are now.</h2>
<script>
var firstName; // variable that will store user name
$("form#greeting").submit(function(event){
console.log( $('#firstName').val() );
firstName = $('#firstName').val();
event.preventDefault();
$("#firstName").val(''); //clean input#firstName
$('form, #question').css('display', 'none'); //hide form
$('#instruction').css('display', 'block'); //show instruction
$('span.userName').text(firstName); //Add name to span.userName
})
</script>
</body></html>
What can we do by getting the user's text input?
- address him/her by name.
- ask him/her other questions. E.g. where are you?
- store his/her answers
