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

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 leftmost 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 SWF file. For more
information, see "About allowing cross-domain data loading" in Using ActionScript in Flash.
If you want to load variables into a target MovieClip, use loadVariables() instead of
loadVariablesNum().
Parameters
url:String - An absolute or relative URL where the variables are located. 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.
level:Number - An integer specifying the level in Flash Player to receive the variables.
method:String [optional] - Specifies 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.
Example
The following example loads information from a text file called params.txt into the main
Timeline of the SWF at level 2 in Flash Player. The variable names of the text fields must
match the variable names in the params.txt file. The setInterval() function is used to
check the progress of the data being loaded into the SWF. The script checks for a variable in
the params.txt file named done.
loadVariablesNum("params.txt", 2);
function checkParamsLoaded() {
if (_level2.done == undefined) {
trace("not yet.");
} else {
trace("finished loading. killing interval.");
trace("-------------");
for (i in _level2) {
