Override or cancel .prepend

Override or cancel .prepend

Hi,

$(document).ready(function() {

    $('#menu ul ul li').prepend('~ ');

});

This chunk of code is in a .js file that is link to every pages of the site I'm working on (called via an include). I linked another .js file to all the pages of a new section I'm developping. Is there a way to override or cancel the .prepend with my section specific .js file??

I tried to use .remove() but I can't make it remove only ~ 

Thanks,
