    <p>What I am trying to achieve is to graph a table using Google's graph API, when the page loads, it queries my REST server for the JSON data. This is my Javascript function. </p> <p>The JavaScript console doesn't show any errors.</p> <pre><code> $(document).ready(function() { $.ajax({ url: 'http://localhost:8004/project5', dataType: "json", async:false, error: function(error){ console.debug(error); }, success: function(data) { alert("YESSSSS"); var data = data.results; for(var i=0; i&lt;data.length; i++) { mytable[arraysize] = new terms(data[i].term1, data[i].term2, (data[i].contains)/((data[i].contains)+ (data[i].notcontains))); arraysize +=1; } drawTable(); } }); }); </code></pre> <p>This Is the JSON that is returned when I query the server in my browser using "<a href="http://localhost:8004/project5" rel="nofollow">http://localhost:8004/project5</a>"</p> <pre><code>{ "results":[ { "term1":"test", "term2":"hard", "contains":"32", "notcontains":"55" }, { "term1":"test", "term2":"easy", "contains":"32", "notcontains":"55" }, { "term1":"pizza", "term2":"hut", "contains":"32", "notcontains":"55" } ] } </code></pre> <p>The html contents of content isn't set to "YESSSS" which i was using to test to see if the function was a success. When the page loads, the rest server recognizes that it is queried and successfully returns the JSON, so I believe the problem is getting the data out of the returned JSON. Which is where I am stuck.</p> <p>EDIT: it seems that my success function isn't being called. This is the function that is called in the java REST server, JAX-RS. To produce the JSON.</p> <pre><code> @GET @Produces(MediaType.APPLICATION_JSON) public String getStudentByid(@QueryParam("id") String id) { System.out.println("Queried"); if (id == null) return Terms.stringTerms(container); return Terms.getTermsByFirst(container, id); } </code></pre> <p>I am getting a <code>XMLHttpRequest cannot load http://localhost:8004/project5/terms.json. Origin null is not allowed by Access-Control-Allow-Origin.</code> error now</p>

    3. COThe `content` element has a class of "content" and not an ID, correct? I ask because the ID situation seems more likely.

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).
