js error on swipe to delete implementation

[ShashankaNataraj]

I copy pasted

Swiped.init({
        query: 'li',
        right: 400,
        onOpen: function () {
          this.destroy(true)
        }
      });

from the readme and get:

everytime an element is swiped.

But, changing:

if (isRemoveNode) {
            this.elem.parentNode.removeChild(this.elem);
        }

to

if (isRemoveNode && this.elem.parentNode) {
            this.elem.parentNode.removeChild(this.elem);
        }

doesnt give out any errors.
