<!-- 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.
Example
beforeBtn.addEventListener('click', function() {
para.insertAdjacentText('afterbegin',textInput.value);
});
afterBtn.addEventListener('click', function() {
para.insertAdjacentText('beforeend',textInput.value);
});
Have a look at our [[../../../../../../../mdn.github.io/dom-examples/insert-adjacent/insertAdjacentText|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.
Polyfill
You can polyfill the insertAdjacentText() method
in Internet Explorer 5.5 (maybe earlier) and higher with the following code:
if (!Element.prototype.insertAdjacentText) Element.prototype.insertAdjacentText = function(type, txt){ this.insertAdjacentHTML( type, (txt+'') // convert to string .replace(/&/g, '&') // embed ampersand symbols .replace(/</g, '<') // embed less-than symbols ) }
