JavaScript DOM HTML method: hasChildNodes()
[this page | pdf | back links]
The hasChildNodes() method (when applied to
HTML
elements in the JavaScript
DOM) returns true if the element has any child
nodes, otherwise it returns false.
Note: whitespace inside a node is deemed to form a (child) text node, and so
will result in a true value
being returned by this method.
It
has the following syntax with no parameters. It returns a Boolean as above.
It can be applied to any node, but if the node is not an element then it will
always return false.
element.hasChildNodes()
