I have the following html page: 

<!DOCTYPE HTML>
<html>
  <head>
    <title>Web Worker Example</title>
  </head>
 <body>
  <p>The time is now: <span id="result" /></p>
  <script>
var worker  = new Worker('worker.js');
worker.onmessage = function (event) {
document.getElementById('result').innerText = event.data;
    };
  </script>
 </body>
</html>

And the worker.js is simply: 

setInterval(function() {
        postMessage(new Date());
}, 2000);

This works fine in Chrome but I get nothing after "The Time Is Now:" in FireFox?

Ideas?

Thanks,

Ray

I just noticed my initial post got all jacked up!

Here is the html:

<title>Web Worker example</title>

The time is now:

<script> var worker = new Worker('worker.js'); worker.onmessage = function (event) { document.getElementById('result').innerText = event.data; }; </script>

And worker.js:

setInterval(function() { 

   postMessage(new Date());

}, 2000);

Again, this works in Chrome but not FireFox.

I did post to Stack Overflow. So far no responses. This should not be that hard of a question. I'm pretty sure this should work in FF. I just don't know if I need to set something in about:config or not?

Thanks for fixing it. What was the issue? You can't cut and paste?

Current Firefox versions do not support innerText, so you need to use innerHTML to make it work in Firefox. The code will work in Firefox 45 and later.
