WordPress JavaScript error

Question

I am having a javascript error on my site http://fightgifs.com with this line of code in footer.php:

var main_menu=new main_menu.dd("main_menu");

Uncaught TypeError: Cannot read property 'dd' of undefined

Anyone has an idea what to do ? The error is creating a problem for a javascript plugin (Shashin). Whole script:

<script type="text/javascript">

jQuery(document).ready(function($){

$('.carousel').elastislide({

    imageW  : 145,

    minItems    : 2,

    margin      : 10

});

var main_menu=new main_menu.dd("main_menu");

main_menu.init("main_menu","menuhover");

});

</script>

The main_menu you expected this to refer to is actually being shadowed.

var main_menu = new main_menu.dd("main_menu");

Both mentions of main_menu actually refer to the local variable being declared, which will be undefined rather than an object with a .dd() method.

To avoid this, you'll have to rename one of them.

var menu = new main_menu.dd("main_menu");

menu.init("main_menu","menuhover");

Or, if you don't need the var afterwards, you can also skip it:

new main_menu.dd("main_menu")
    .init("main_menu","menuhover");

Thanks for helping, however now I get Uncaught ReferenceError: main_menu is not defined

@MartinLaumets Well, that depends on what main_menu was expected to be and what is supposed to be defining it. It might actually have a different name. It might be a property of another object rather than a global. If it's from a WordPress plugin, it could be that some the plugin's files aren't being included in the pages.

Your code of main_menu object has a problem. Post your code related to main_menu or check code yourself.

it's also probably a bad idea to redefine the object to a variable . . .
