Remove All Images

Question

What JavaScript will remove all image tags?

Answer 1

The previous answer will only remove every second image.

Remember NodeLists returned by getElementsByTagName or other DOM methods are ‘live’. That means when you remove image 0, images 1–n move down to 0–(n-1); this is a ‘destructive iteration’.

To avoid this, either make a static Array copy of the NodeList (as the jQuery answer is effectively doing), or, faster, just iterate the list backwards:

for (var i= document.images.length; i-->0;)
    document.images[i].parentNode.removeChild(document.images[i]);
