I\'m looking for someone to explain how to drag and drop in javascript, I want a horizontal line with some customizable images in it.

I\'ve had a look at the online

Answer 1

Find 2x of:

dragHelper.style.top  = mousePos.y - mouseOffset.y;
dragHelper.style.left = mousePos.x - mouseOffset.x;

change to:

dragHelper.style.top  = mousePos.y - mouseOffset.y + 'px';
dragHelper.style.left = mousePos.x - mouseOffset.x + 'px';

Works on FF. 3.6
