Question

i wanna create a simple bookmarklet that hides all images from the current website i’m browsing.

javascript:body.getElementsByTagName("img").style.visibility="hidden";

that’s not working? i wonder what i’m doing wrong?

thank you for your help!

Answer 1

You need to iterate over the array-like object returned from document.getElementsByTagName, e.g.:

var imgs = document.getElementsByTagName("img");
for (var i = 0; i < imgs.length; i++) {
    imgs[i].style.visibility = "hidden";
}

Edit:

The complete bookmarklet URI:

javascript:(function(){var imgs=document.getElementsByTagName("img");for(var i=0;i<imgs.length;i++)imgs[i].style.visibility="hidden"}());
