    <p>Does Message Channel work in Shared Workers? I want to create some kind of communication between several Shared Workers, so I took example from <a href="http://www.antkorp.in/workersComm/" rel="nofollow">here</a> and change it into this:</p> <pre><code>$(function() { var worker1 = new SharedWorker("worker1.js"); var worker2 = new SharedWorker("worker2.js"); var channel=new MessageChannel(); worker1.port.start(); worker2.port.start(); worker1.port.onmessage = function(e) { $("#log").append("&lt;br&gt;" + e.data); console.log(e.data); } worker1.port.postMessage({ code : "start", msg : "ping" },[channel.port1]); worker2.port.onmessage = function(e) { $("#log").append("&lt;br&gt;" + e.data); console.log(e.data); } worker2.port.postMessage({ code : "start", msg : "ping" },[channel.port2]); /*channel.port1.postMessage("channel port1 msg"); channel.port1.onmessage=function(e){ $("#log").append("&lt;br&gt; port1 recieved msg : " + e.data); console.log(e.data); }*/ $("#send1").click(function() { var msg = $("#msg").val(); if (msg &amp;&amp; msg != "start") worker1.port.postMessage({ code : "msgw", msg : "ping2" }); $("#msg").val(""); }) $("#send2").click(function() { var msg = $("#msg").val(); if (msg &amp;&amp; msg != "start") worker2.port.postMessage({ code : "msgw", msg : "ping3" }); $("#msg").val(""); }) $("#send3").click(function() { var msg = $("#msg").val(); if (msg &amp;&amp; msg != "start") worker1.port.postMessage({ code : "msgch", msg : "ping3" }); $("#msg").val(""); }); $("#send4").click(function() { var msg = $("#msg").val(); if (msg &amp;&amp; msg != "start") worker2.port.postMessage({ code : "msgch", msg : "ping3" }); $("#msg").val(""); }) }); </code></pre> <p>worker1.js and worker2.js:</p> <pre><code>var channelPort; function getChannelMessage(e){ postMessage(e.data+" &gt;&gt; channel recieved msg in worker1 "); } self.onconnect = function(e){ var port = e.ports[0]; port.onmessage = function(e) { if (e.data.code == "start") { channelPort = e.ports[0]; channelPort.start(); channelPort.postMessage(e.data.msg+" &gt;&gt; worker1 channel post"); channelPort.onmessage = getChannelMessage; } else if(e.data.code=="msgw") { port.postMessage(e.data.msg+" &gt;&gt; worker1 got msg"); }else if(e.data.code=="msgch") { channelPort.postMessage(e.data.msg+" &gt;&gt; worker1 got msg"); } }; port.start(); } </code></pre> <p>But when I send message from worker1 I don't receive it in worker2. Am I doing something wrong or is it impossible to do? Is there any other way of communicating two Shared Workers without posting message to browser tab?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
