XML.sendAndLoad()
Availability
Flash Player 5; behavior changed in Flash Player 7.
Usage
my_xml.sendAndLoad(url, targetXMLobject)
Parameters
url
The destination URL for the specified XML object. If the SWF file issuing this call is
running in a web browser,
url must be in the same domain as the SWF file; for details, see
“Description,” below.
targetXMLobject An XML object created with the XML constructor method that will receive
the return information from the server.
Returns
Nothing.
Description
Method; encodes the specified XML object into a XML document, sends it to the specified URL
using the
POST method, downloads the server’s response and then loads it into the
targetXMLobject specified in the parameters. The server response is loaded in the same manner
used by the
load() method.
In SWF files running in a version of the player earlier than Flash Player 7,
url must be in the
same superdomain as the SWF file that is issuing this call. For example, a SWF file at
www.someDomain.com can load variables from a SWF file at store.someDomain.com, because
both files are in the same superdomain of someDomain.com.
In SWF files of any version running in Flash Player 7 or later,
url must be in exactly the same
domain (see “Flash Player security features” on page 188). For example, a SWF file at
www.someDomain.com can load variables only from SWF files that are also at
www.someDomain.com. If you want to load variables from a different domain, you can place a
cross-domain policy file on the server hosting the SWF file that is being accessed. For more
information, see “About allowing cross-domain data loading” on page 190.
When
load() is executed, the XML object property loaded is set to false. When the XML data
finishes downloading, the loaded property is set to true, and the onLoad() method is invoked.
The XML data is not parsed until it is completely downloaded. If the XML object previously
contained any XML trees, they are discarded.
