Body
<p>I have an AJAX function I'd like to kill, but it is outside of the function. Take a look:</p> <pre><code>function waitForMsg(){ var heartbeat = $.ajax({ type: "GET", url: "includes/push_events.php", tryCount : 0, retryLimit : 3, async: true, cache: false, // timeout: 500, success: function(data){ console.log(data); if(data){ if(data.current_date_time){ updateTime(data.current_date_time); } if(data.color){ console.log("Receiving data"); displayAlert(data.color, data.notification_message, data.sound, data.title); } if(data.user_disabled){ console.log("Receiving data"); fastLogoff(); checkDisabled(); } } setTimeout( waitForMsg, 5000 ); }, error: function(data){ if (data.status == 500) { console.log("Connection Lost to Server (500)"); $.ajax(this); } else { console.log("Unknown Error. (Reload)"); $.ajax(this); } }, dataType: "json" }); }; // Detect browser open. $(document).ready(function(){ // window.onunload = function(){alert('closing')}; // mainmode(); $('#alertbox').click(function(){ $('#alertbox').slideUp("slow"); }); $(document).ready(function(){ $('#alertbox').click(function(){ $('#alertbox').slideUp("slow"); }); // Check focal point var window_focus = true; $(window).focus(function() { window_focus = true; console.log('Focus'); }); $(window).blur(function() { window_focus = false; console.log('Blur'); }); setInterval(function(){ if(window_focus == true){ console.log('in focus'); waitForMsg(); }else{ console.log('out of focus'); heartbeat.abort(); } }, 5000); }); }); </code></pre> <p>If you notice, the ajax is outside of the document.ready. I am trying to kill the ajax calls if the user goes to a different window, then restart the calls once the return to the window. The start works, but if the user goes away from the window, it gives me the "heartbeat is not defined". Obviously this is because its outside of that function. Any work arounds?</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.
