    <p>I have been trying to use json and ajax with jquery and I am running in to some trouble. I am trying to get data from a json file to display on my page.</p> <p>At the moment I am just trying to send it to the console but I am getting null in the console. I am not sure what I am doing right and what I am doing wrong so I was just wondering if I could get some pointers.</p> <p>This is what I have for the request</p> <pre><code>$(document).ready(function() { var json = (function () { var json = null; $.ajax({ 'async': false, 'global': false, 'url': 'js/refs.json', 'dataType': "json", 'success': function (refs) { json = refs; } }); return json; })(); console.log(json); </code></pre> <p>This is what is in refs.json</p> <pre><code>var refs = { "referee": [ { "name": "Ellie", "company": "University", "position": "Lecturer", "address": "", "phone": "5750", "email": "ellie@ac.uk", "type": "Education" }, { "name": "Matthew", "company": "", "position": "", "address": "23 High Street", "phone": " 962", "email": "matthew@aaa.com", "type": "Character" } ], "project": [ { "tab": "Dissertation", "title": "Can technology in the home be used to enhance learning of numeracy, in conjunction with the nantional curriculum", "yr": "2013", "link": [ { "name": "Artefact", "links": "fypc", "size": "", "misc": "" } ], "docs": [ {"type": "doc", "links": "fyp.docx", "size" :"3.78MB", }, {"type": "pdf", "links": "fyp.pdf", "size" :"1.76MB", } ], "purpose": "School - Anglia Ruskin University", "grade": "Not yet awarded", "sshot": "fypc.png" }, { "tab": "Network and IT Operations", "title": "Virtual inter-office network with firewall. (Built using PacketTracer 5.3.3)", "yr": "2013", "link": [ { "name": "Serial Cable Connection Version", "links": "", "size": "204KB", "misc": "(Submitted version)" }, { "name": "Frame Relay Version", "links": "", "size": "129KB", "misc": "" }, { "name": "Packet Tracer 5.3.3 Download", "links": "", "size": "48.2MB", "misc": "(.zip)" } ], "docs": [ { "type": "doc", "links": "nio.docx", "size" :"223KB", }, { "type": "pdf", "links": "nio.pdf", "size" :"943.KB", } ], "purpose": "School - Anglia Ruskin University", "grade": "Not yet awarded", "sshot": "nio1.png" } ] }; </code></pre> <p>As I say, the response from the console using console.log is null. I can't see where I am going right or wrong. The request is a snippet I got from a post on here (<a href="https://stackoverflow.com/questions/2177548/load-json-into-variable">load json into variable</a>)</p> <p>Any pointers would be much appreciated</p> <p>Thanks in advance</p>

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.
