    <p>I trigger the following function when a tooltip is clicked. It is an ajax poll.</p> <p>There can be many tooltips on the page, and more than one can need access to the data retrieved from the server.</p> <p>What I want to achieve is to have this poll running as one instance - so if the user clicks a different tooltip the polling stops, rather than being duplicated.</p> <p>Would be grateful if you could help.</p> <p>Thanks</p> <pre><code>function doConversationsAjaxLongPoll(tablename){ clientSubmit = new Object; // HERE WE'RE GOING TO GET A LIST OF THE ROWIDS THAT WE NEED TO POLL FOR, MAKE AN OBJECT OUT OF THEM. DO THIS BY LOOKING AT WHICH //TOOLIPS HAVE CLASS OPEN var tooltips = []; $('.tooltipOpen').each(function(index){ tooltips.push($(this).data('idrow')) }) console.log("tooltips length: " + tooltips.length) if(tooltips.length==0){ // console.log("tooltip length is 0 so we're returning false") return false } clientSubmit.OpenConversations = tooltips clientSubmit.tablename = tablename clientSubmit.CurrentData = $('body').data('conversations') console.log(clientSubmit) $.ajax({ type: 'POST', url: '/conversations.php?loadNew=1', data: clientSubmit, timeout: 25000, success: function(data){ console.log('success') data=JSON.parse(data) console.log(data) $('body').data('conversations', data) }, complete: function(status, jqXHR){ if(tooltips.length==0){ // console.log("tooltip length is 0 so we're returning false") return false } else { doConversationsAjaxLongPoll(tablename); } } }); updateConversations() } </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.
