This url throws a missing ) after argument error. It is being dynamically generated by PHP. I cannot figure out the correct sequence/placement of single and double quotes to render it.

<a href="cards.html" onmouseover="jQuery('.menu-image li').html('<img src='cards_1.png' />');">Cards</a>

The particular effect desired is to onmouseover insert an image into .menu-image li. All I can figure out is that the img src with the quotes (I’ve tried single and double) is not liked and throws the argument error.

    Try escaping the incorrect quotes with \ or \\.

    I.e. html('<img src=\'cards_1.png\' />');

    Alternatively, you can just use &quot;. An URL encoder should have done this for you automatically.

    A very popular error btw. is to not encode every & in an URL as &amp;. Browsers usually guess right what was intended though, so people never learn. But the link

    <a href="test.php?a=1&b=2">example</a>

    is actually incorrect and should be

    <a href="test.php?a=1&amp;b=2">example</a>

    Now if you had been using an URL encoder instead of just “printing” the string, it should automatically have converted your double quote to &amp; and probably saved you some headaches.
