Empty ()

Delete all child elements

Syntax:

Myelement. Empty ();

Return Value:

• (Element) Main adjustment element

Example: HTML

<Div id = "myelement"> <p> </P> <span> </div>

Javascript

$ ('Myelement'). Empty ();

Result html <Div id = "myelement"> </div>

Element Method: Destroy

Delete the element itself and all its child elements (and perform memory garbage collection)

Syntax:

Myelement. Destroy ();

Return Value:

• (Null)

In addition, I found that for an array of classname = "option", $ ('. option '). empty () does not work. It is possible that empty takes effect on the ID at this time.

You can use $ ('. option'). Destroy.
