FLASH® LITE™ 2.x - Adobe Help and Support

Downloads variables from the specified URL, parses the variable data, and places the resulting
variables into my_lv. Any properties in my_lv with the same names as downloaded variables
are overwritten. Any properties in my_lv with different names than downloaded variables are
not deleted. This is an asynchronous action.
The downloaded data must be in the MIME content type application/x-www-form-urlencoded.
This is the same format used by loadVariables().
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. 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 sources at store.someDomain.com because both
files are in the same superdomain named someDomain.com.
In SWF files of any version running in Flash Player 7 or later, url must be in exactly the same
domain. 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 SWF file.
Also, in files published for Flash Player 7, case-sensitivity is supported for external variables
loaded with LoadVars.load().
This method is similar to XML.load().
Parameters
url:String - A string; the URL from which to download the variables. 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 the Description section.
Returns
Boolean - false if no parameter (null) is passed; true otherwise. Use the onLoad() event
handler to check the success of loaded data.
Example
The following code defines an onLoad handler function that signals when data is returned to
the Flash application from a server-side PHP script, and then loads the data in passvars.php.
var my_lv:LoadVars = new LoadVars();
my_lv.onLoad = function(success:Boolean) {
if (success) {
trace(this.toString());
} else {
trace("Error loading/parsing LoadVars.");
}
