Issue #32 (normalize() + splitText(), jQuery, Mobile, GUI)02/27/14
In most cases, a text node is counted as a single node in the DOM tree. But if you add a text node to an element as a sibling element (e.g. using appendChild()), the element will then have more than one text node:
var el = document.getElementById('el');
console.log(el.childNodes.length); // 2
The log in that code would produce a length value of "2" after the text node is appended.
If you want to merge these text nodes, you can use a little-known method called normalize():
console.log(el.childNodes.length); // 1
As shown, this would produce a length value of 1, as was the case prior to adding the second text node.
You can also use a method that is the opposite of normalize(), and that's the splitText() method:
console.log(el.childNodes.length); // 2
console.log(el.firstChild.nodeValue + el.lastChild.nodeValue);
splitText() takes an argument specifying the offset to define where to do the split.
To see these two methods in action, check out this JS Bin demo. Pay close attention to the way the HTML starts out, and how the output progresses. As for browser support, one book I own says these methods are supported in IE6-8 but other sources say they aren't. At the very least, they're supported everywhere including IE9+.
More info on normalize() and splitText() on MDN.
