The loadVariables method can also be used to update variables in the active movie clip with
new values.
The
loadVariables method requires that the text of the URL be in the standard MIME
format: application/x-www-form-urlencoded (CGI script format).
In SWF files running in a version earlier than Flash Player 7,
url must be in the same
superdomain as the SWF file that is issuing this call. A superdomain is derived by removing
the left-most component of a file's URL. For example, a SWF file at www.someDomain.com
can load data from a source 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 as the SWF file that is issuing this call. For example, a SWF file at
www.someDomain.com can load data only from sources that are also at
www.someDomain.com. To load data from a different domain, you can place a cross-domain
policy file on the server hosting the data source that is being accessed.
To load variables into a specific level, use
loadVariablesNum() instead of
loadVariables().
You can extend the methods and event handlers of the MovieClip class by creating a subclass.
Availability: ActionScript 1.0; Flash Lite 2.0 - Behavior changed in Flash Player 7.
Parameters
url:String - The absolute or relative URL for the external file that contains the variables to
be loaded. 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.
method:String [optional] - Specifies an HTTP method for sending variables. The parameter
must be the string
GET or POST. If no variables are sent, omit this parameter. The GET method
appends the variables to the end of the URL and is used for small numbers of variables. The
POST method sends the variables in a separate HTTP header and is used for long strings of
variables.
