MovieClip.loadVariables()
Availability
Flash Player 5; behavior changed in Flash Player 7.
Usage
my_mc.loadVariables(url:String [, variables:String]) : Void
Parameters
url
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.
variables An optional parameter specifying an HTTP method for sending variables. The
parameter must be the string
GET or POST. If there are no variables to be 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.
Returns
Nothing.
Description
Method; reads data from an external file and sets the values for variables in my_mc. The external
file can be a text file generated by ColdFusion, a CGI script, Active Server Page (ASP), or PHP
script and can contain any number of variables.
This method can also be used to update variables in the active movie clip with new values.
This 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 (see “Flash Player security features” in Using
ActionScript in Flash). For example, a SWF file at www.someDomain.com can load data only
from sources that are also at www.someDomain.com. If you want 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. For more information, see “About allowing cross-domain data loading” in Using
ActionScript in Flash.
If you want to load variables into a specific level, use
loadVariablesNum() instead of
loadVariables().
