- The async IDL attribute controls whether the
element will execute asynchronously or not. If the element's "force-async" flag is
set, then, on getting, the async IDL attribute must return
true, and on setting, the "force-async" flag must first be unset, and then the
content attribute must be removed if the IDL attribute's new value is false, and must be set to
the empty string if the IDL attribute's new value is true.
- The IDL attribute text must return a
concatenation of the contents of all the Text nodes that are children of the
script element (ignoring any other nodes such as comments or elements), in tree
order. On setting, it must act the same way as the textContent IDL attribute.
