Anyone here know how to use Mutation Observer please help me!
Here's one from MDN. There are many other googlable examples.
To hide all added images (hiding is arguably faster than deleting) you can use something like this:
var mo = new MutationObserver(function(mutations){
for (var m, i=0, mlen=mutations.length; i<mlen && (m=mutations[i]); i++)
for (var nodes=m.addedNodes, n, j=0, nlen=nodes.length; j<nlen && (n=nodes[j]); j++)
if (n.nodeType == 1) { // Node.ELEMENT_NODE
var imgs = (n.tagName == 'IMG') ? [n] : n.getElementsByTagName('img');
for (var img, k=imgs.length-1; (k>=0) && (img=imgs[k]); k--)
img.style.display = 'none';
}
});
mo.observe(document, {subtree:true, childList:true});
Thank you very much!

Hi everybody, I'm trying to write a Anti AdBlock Blocker that work like detect element that gonna added to page, if it match my condition then remove it.
I know that there is "DomContentInserted" but it is now outdate, so I really want to use Mutation Observer because it is overall better.
Anyone can give me an example like this, many thank:
Use Mutation Observer to detect img tag going to add to the page, if match then set that img tag outerHTML = ""; to remove, and script should run at document-start for testing only, probably after I figure something then I can dig it and make it become a Anti Ablock Blocker soon, but at this time Mutation Observer, I know nothing about it but only an example that help my situation is enough.
