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 */
