If that’s the only class that you set to <body>, then remove all the classes

$("body").removeClass();

// or
document.body.className = "";

If not, go the plain DOM way, use a regular expression to strip the class name out of the string.

document.body.className = document.body.className.replace(/\blightbox\d+/, "");

The jQuery way is a bit more complicated here:

$("body").removeClass(function (index, oldClass) {
   var matches = oldClass.match(/\blightbox\d+/) || [];
   return matches[0];
});
