Text.isElementContentWhitespace
Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Note: You may replace it with /\s+/.test(Text.data)
, /\s+/.test(Text.nodeValue)
, or /\s+/.test(Text.textContent)
. Putting any property that represents the textual content of the Text
node into test()
should do the same work just like the three example above.
The Text.isElementContentWhitespace
read-only property returns a Boolean
flag indicating whether or not the text node's content consists solely of whitespace.
Syntax
b = textnode.isElementContentWhitespace;
Example
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 */
