Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The Text.isElementContentWhitespace read-only property returns a Boolean flag indicating whether or not the text node's content consists solely of whitespace.
b = textnode.isElementContentWhitespace;
In the example below, we create a node with mixed display and whitespace characters and the attribute is false.
var tn = document.createTextNode("Hello world");
tn.isElementContentWhitespace; /* evaluates to false */
For a node that is all whitespace characters, the isElementContentWhitespace evaluates to true.
var ws = document.createTextNode(" \t \r\n ")
ws.isElementContentWhitespace; /* evaluates to true */
