Visualization of position names
html
<!-- beforebegin -->
<p>
<!-- afterbegin -->
foo
<!-- beforeend -->
</p>
<!-- afterend -->
Note: The beforebegin
and
afterend
positions work only if the node is in a tree and has an element
parent.
Examples
js
beforeBtn.addEventListener("click", () => {
para.insertAdjacentText("afterbegin", textInput.value);
});
afterBtn.addEventListener("click", () => {
para.insertAdjacentText("beforeend", textInput.value);
});
Have a look at our insertAdjacentText.html
demo on GitHub (see the source code too.) Here we have a simple paragraph. You can enter some text into the form
element, then press the Insert before and Insert after buttons to
insert it before or after the existing paragraph text using
insertAdjacentText()
. Note that the existing text node is not added to —
further text nodes are created containing the new additions.
