Add text before or after an HTML element

Question

If i have an HTML element like

with some text inside or another elements can I add before or after this div some text data without an html element,

Answer 1

Yes, you can create a text node with document.createTextNode('the text')

Then you can insert it like an element, with appendChild or insertBefore.

Example that insert a text before #childDiv:

var text = document.createTextNode('the text');
var child = document.getElementById('childDiv');
child.parentNode.insertBefore(text, child);
