<p>Test required here: File -> Work Offline - toggle the value and there <em>should</em> be three list items notifying of online and offline.</p>
|
|
<ul>
|
|
<li>via body "on" events: <span id="viabody"></span></li>
|
|
<li>via window "on" events: <span id="viaon"></span></li>
|
|
<li>via window.addEventListener: <span id="vialistener"></span></li>
|
|
</ul>
|
|
<p>Note that the test shows that <code>window.ononline</code> and <code>window.onoffline</code> doesn't work (which I thought I had read in the specs somewhere...).</p>
