How can I implement prepend and append with regular JavaScript?

Here's a snippet to get you going:

theParent = document.getElementById("theParent");theKid = document.createElement("div");theKid.innerHTML = 'Are we there yet?';// append theKid to the end of theParenttheParent.appendChild(theKid);// prepend theKid to the beginning of theParenttheParent.insertBefore(theKid, theParent.firstChild);

theParent.firstChild will give us a reference to the first element within theParent and put theKid before it.

Perhaps you're asking about the DOM methods appendChild and insertBefore.

parentNode.insertBefore(newChild, refChild)

Inserts the node newChild as a child of parentNode before the existing child node refChild. (Returns newChild.)

If refChild is null, newChild is added at the end of the list of children. Equivalently, and more readably, use parentNode.appendChild(newChild).

You didn't give us much to go on here, but I think you're just asking how to add content to the beginning or end of an element?If so here's how you can do it pretty easily:

//get the target div you want to append/prepend tovar someDiv = document.getElementById("targetDiv");//append textsomeDiv.innerHTML += "Add this text to the end";//prepend textsomeDiv.innerHTML = "Add this text to the beginning" + someDiv.innerHTML;

Pretty easy.
