When using href='#/' or any other href starting with '#' in jquery.mmenu plugin the following exception is fired:
Syntax error, unrecognized expression: #
HTML
<body>
<nav id="my-menu">
<ul>
<li><a href="#/">Home</a></li>
<li><a href="#/about/">About us</a></li>
<li><a href="#/contact/">Contact</a></li>
</ul>
</nav>
<div>
<div id="my-header">
<a href="#my-menu">Open the menu</a>
</div>
</div>
</body>
JS
$(document).ready(function() {$("#my-menu").mmenu();});
Although the execution is not affected and the page loads as expected in all cases the error is really annoying.
See the fiddle: Open the menu -> Home see the console.
Posted an issue on github but looking for any workarounds meanwhile
UDPATE
The issue is resolved in 5.3.1
I think it is a sizzle specific error.
Look at this jsfiddle.
This is the same error, i think it means that the selector is not valid. Based on This article I can confirm that the selector is not valid.
So here is your problem :)
