Bootstrap Button onClick is not working

Question

I use bootstrap and have a simple layout including a button. I tried the code solution from here but it is not working. This is my code, it is not even showing 'test' after clicking the search button.

  <title>Search</title>

    </br>
    <button id="search" type="button" class="btn btn-primary">Suchen</button>
    <p><br/></p>
    <p id="output"></p>
    </div>
    <script type="text/javascript">
      $('#search').on('click', function (e) {
        document.getElementById('#output').innerHTML = "test";

        var EventSearch = require("facebook-events-by-location-core");

        var es = new EventSearch({
          "lat": 40.710803,
          "lng": -73.964040
        });

        es.search().then(function (events) {
          console.log(JSON.stringify(events));
          document.getElementById('output').innerHTML = JSON.stringify(events);
        }).catch(function (error) {
          console.error(JSON.stringify(error));
        }); 
      })
    </script>

When using document.getElementByid(), you dont need the # before the id.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    <p id="output"></p>
    </div>
    <script type="text/javascript">
      $('#search').on('click', function (e) {
        document.getElementById('output').innerHTML = "test";
        // I removed the event search code because I do not have the files and it was breaking the example.
      })
    </script>

If I run the code snippet in stackoverflow it works, but if I run the same from sublimetext it does not work. — 10jo10, Apr 26 '17 at 16:33
If this is your only code, it looks like you are not including jQuery, which would make $('#search').on(... break. — Ken, Apr 26 '17 at 19:09
Thank you for your answer. But I am saying , isn't this including jquery? Path and filename are also correct. — 10jo10, Apr 26 '17 at 19:20
Oh, yes, that would include them. I missed them because they are below the rest of your code. What is the error message in the console when you run this locally? — Ken, Apr 26 '17 at 19:41
It says 'Uncaught ReferenceError: $ is not defined' and points at this line: $('#search').on('click', function (e) { — 10jo10, Apr 26 '17 at 20:16
Thank you all for your help, I finally found the error, I had to include jquery at the top of my . It was used before it was included. — 10jo10, Apr 26 '17 at 20:26

First of all, don't use the "#" sign when using document.getElementById. Secondly, you need to add the "require" reference.

Check the console message:

 $('#search').on('click', function (e) {
        document.getElementById('output').innerHTML = "test";

        var EventSearch = require("facebook-events-by-location-core");

        var es = new EventSearch({
          "lat": 40.710803,
          "lng": -73.964040
        });

        es.search().then(function (events) {
          console.log(JSON.stringify(events));
          document.getElementById('output').innerHTML = JSON.stringify(events);
        }).catch(function (error) {
          console.error(JSON.stringify(error));
        }); 
      })

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="container-fluid">
      <h1>Welcome!</h1>
    </br>
    <button id="search" type="button" class="btn btn-primary">Suchen</button>
    <p><br/></p>
    <p id="output"></p>
    </div>

If I comment out the search part it still does not work (it does not show 'test') from my sublime text editor. — 10jo10, Apr 26 '17 at 16:34
