To answer the original question - there are various ways to do this  but the following would be the simplest   If you already have a handle to the child node that you want to remove  i e  you have a JavaScript variable that holds a reference to it   myChildNode parentNode removeChild myChildNode     Obviously  if you are not using one of the numerous libraries that already do this  you would want to create a function to abstract this out   function removeElement node        node parentNode removeChild node         EDIT  As has been mentioned by others  if you have any event handlers wired up to the node you are removing  you will want to make sure you disconnect those before the last reference to the node being removed goes out of scope  lest poor implementations of the JavaScript interpreter leak memory
