I have this working code:
a.parentNode.removeChild(a);
I need to also remove this child's previous sibling, ie the element that comes before it.
How do I update this? Does MDN have documentation on it?
Ok, here is a solution which takes into account that the previous sibling might not be an element node:
var previous = a.previousSibling;
// iterate until we find an element node or there is no previous sibling
while(previous && previous.nodeType !== 1) {
previous = previous.previousSibling;
}
// if there is a sibling, remove it
if(previous) {
previous.parentNode.removeChild(previous);
}
Reference: Node.previousSibling
[MDN]
You could easily create a function which gives you the previous element node.
I will repeat my comment here:
You can find a reference of all DOM interfaces at MDN , in particular, the Node
interface .
