TypeError: body is null

[ipepe]

I included mdb.js in head and Im getting

TypeError: body is null

Code:

   Waves.init = function (options) {
        var body = document.body;

        options = options || {};

        if ('duration' in options) {
            Effect.duration = options.duration;
        }

        if ('delay' in options) {
            Effect.delay = options.delay;
        }

        if (isTouchAvailable) {
            body.addEventListener('touchstart', showEffect, false);
            body.addEventListener('touchcancel', TouchHandler.registerEvent, false);
            body.addEventListener('touchend', TouchHandler.registerEvent, false);
        }

        body.addEventListener('mousedown', showEffect, false); //TypeError: body is null
    };

Error is marked on last line

I think it should be added to the end of the body tag.

Dear ipepe, you are including js in head, due to that when website JS and try to assign body to the variable it cannot do this because this elements wasn't crated yeat (body tag is below head). You have to place your script below body.

Lol, I know what happend. I just assumed that placing script src tags in head is something normal in modern web development. I guess I will have to patch it myself.
