    <p>In your AJAX call you use global <code>event</code> object, which is not cross-browser and shouldn't be used (e.g. Firefox doesn't have it).</p> <p>Pass event in function call instead:</p> <pre><code>$('#remove_session').click(function(e){ e.preventDefault(); // rest of your code }); </code></pre> <p>If you do it that way, jQuery takes care about cross-browser normalization and proper behaviour.</p> <p>See also <a href="https://stackoverflow.com/questions/8838635/event-preventdefault-working-in-chrome-not-firefox-for-a-submit-button">this question</a> to learn more about difference between global <code>event</code> object and event passed into function.</p> <hr> <p><strong>If it still doesn't work</strong></p> <ul> <li>open developer tools in Chrome (F12)</li> <li>check in your console (<em>Console</em> tab) if there are any error reports after you click a button</li> <li>also, open <em>Network</em> tab and see if after clicking a button any request is made; what is response status?</li> <li>make sure your controller works with GET requests (as you don't specify request type, and <code>GET</code> is default)</li> <li>you may also try adding <code>dataType: "json"</code> to your AJAX request, but this shouldn't be a problem as Symfony's <code>JsonResponse</code> should already provide neccessary response headers </li> </ul> <hr> <p><strong>Check other places</strong></p> <ul> <li>error you posted says where the unexpected <code>:</code> is; investigate that line; is the code you have posted here the <code>whole</code> javascript that you have on your page?</li> </ul>

    1. COYeah, I tried this, but to no avail. Doesn't seem to do anything. I am convinced there is something wrong with my approach.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
