MutationObserver wrapper to wait for an element (or elements) with the specified CSS selector.
First, load the function in your script metablock:
.............. // @require https://greasyfork.org/scripts/12228/code/setMutationHandler.js .............. // ==/UserScript==
Usage (single node, one-time change):
setMutationHandler(document, '.container p.some-child', function(observer, nodes) {
nodes[0].remove();
observer.disconnect(); // disconnect the observer, this is useful for one-time jobs
});
Usage (multiple nodes, the page is watched constantly for the added elements):
setMutationHandler(document, '.container p.some-child', function(observer, nodes) {
[].forEach.call(nodes, function(node) {
node.style.display = 'none';
});
return true; // continue enumerating current batch of mutations
});
Usage (observe the changes only inside particular container element):
setMutationHandler(document.querySelector('.container-selector'), '.some-child', function(observer, nodes) {
[].forEach.call(nodes, function(node) {
node.style.display = 'none';
});
return true; // continue enumerating current batch of mutations
});
You may want to make your userscript run at document-start to catch the mutations during page load:
.............. // @run-at document-start // @require https://greasyfork.org/scripts/12228/code/setMutationHandler.js .............. // ==/UserScript==
