I am trying to switch from a very basic webpage into anthor one but i face some issues with the result once i click on `getAll`


My previous webpage (the wroking one )


 <html>
 <head>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
 </head>
 <body>
 <button onclick="getAll()"> Get All The Users </button>
 
 <div id="users"></div>
 
 <script>
 function getAll()
 
 {
 $("#users").html("");
 
 
 
 $.getJSON("http://localhost:8080/users", function(data)
 {
 for (var i in data) {
 $('#users').append("<p>ID: " + data[i].id + "</p>")
 $('#users').append("<p>First name: " + data[i].fname + "</p>")
 $('#users').append("<p>Last name: " + data[i].lname + "</p><br>")
 }
 }); 
 
 }
 
 </script>
 </body>
 </html>




Here is the error:

 Uncaught ReferenceError: getAll is not defined
 at HTMLButtonElement.onclick (testt.html:96)
 onclick @ @ testt.html:96
 testt.html:145 
 
 Uncaught ReferenceError: screenfull is not defined
 at HTMLDivElement.<anonymous> (testt.html:145)
 (anonymous) @ testt.html:145

**EDITED** 
After Nina´s answer i get the desired result but the homepage looks like this:


[The result][2]

So it distorts the upper part of my homepage.
