    <p>You can make your AJAX request synchronous. <a href="https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest/Synchronous_and_Asynchronous_Requests" rel="nofollow">https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest/Synchronous_and_Asynchronous_Requests</a></p> <pre><code>var request = new XMLHttpRequest(); // Last parameter makes it not asnychronous request.open('GET', 'http://www.mozilla.org/', false); request.send(null); // Won't get here until the network call finishes if (request.status === 200) { console.log(request.responseText); } </code></pre> <p>However, that will block the UI while waiting for the server to respond, which is almost never what you want. In that case, you should use a callback to process results.</p> <p>Here's an example using a callback without relying on a global variable. You should always run away from those</p> <pre><code>function ShowInserisciCommerciale( ) { getElementiEsistenti(function(responseText) { JSON.parse(responseText); }); } function getElementiEsistenti(successCallback){ var url = "http://127.0.0.1:8080/Tesi/Ingredienti"; var xmlHttp = new XMLHttpRequest(); xmlHttp.open("POST", url, false); xmlHttp.send(null); xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlHttp.onreadystatechange = function() { if (xmlHttp.readyState == 4) // COMPLETED { if (xmlHttp.status == 200) // SUCCESSFUL { successCallback(xmlHttp.responseText); } else { alert("An error occurred while communicating with login server."); } } }; } </code></pre>

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).
