Need help with XHR Get Requests III

#1

Hello. I’m unable to pass the second step under XHR Get Requests III in Learn Javascript: Requests. Not sure what I’m doing wrong. Thanks for the help.

Here is the code in full.

// Include data for accessing Google APIs

const apiKey = 'AIzaSyAgUw6wr3FIvZkRYf92ha-e0Rn_vwgorBg';
const projection = 'FULL';
const url: "https://www.googleapis.com/urlshortener/v1/url";

// Some page elements

const $inputField = $('#input');
const $expandButton = $('#expand');
const $shortenButton = $('#shorten');
const $responseField = $('#responseField');

// AJAX functions

function expandUrl() {
	const urlToExpand = url + '?key=' + apiKey + '&shortUrl=' + $inputField.val();
}

function shortenUrl() {

}

function expand() {
  $responseField.empty();
  expandUrl();
  return false;
}

function shorten() {
  $responseField.empty();
  shortenUrl();
  return false;
}

// Call functions on submit

$expandButton.click(expand);
$shortenButton.click(shorten);
