This seems like something that would have a quick answer, but I can't find one. Maybe I'm searching the wrong terms? No libraries please, though I don't need cross-browser fallbacks, I'm targeting all the latest versions on this project.
I'm getting some elements:
element = document.querySelectorAll(".someselector");
This is working, but how do I now delete these elements? Do I have to loop through them and do the element.parentNode.removeChild(element); thing, or is there a simple function I'm missing?
Yes, you're almost right. .querySelectorAll returns a frozen NodeList. You need to iterate it and do things.
Array.prototype.forEach.call( element, function( node ) {
node.parentNode.removeChild( node );
});
Even if you only got one result, you would need to access it via index, like
elements[0].parentNode.removeChild(elements[0]);
If you only want to query for one element, use .querySelector instead. There you just get the node reference without the need to access with an index.
