The following example sends a string to the previous SWF file and displays a status message about
whether the local connection was able to connect to the file. A TextInput component called
, a TextArea instance called
name_ti
used to display content.
var sending_lc:LocalConnection;
var sendListener:Object = new Object();
sendListener.click = function(evt:Object) {
sending_lc = new LocalConnection();
sending_lc.onStatus = function(infoObject:Object) {
switch (infoObject.level) {
case 'status' :
status_ta.text = "LocalConnection connected successfully.";
break;
case 'error' :
status_ta.text = "LocalConnection encountered an error.";
break;
}
};
sending_lc.send("_mylc", "sayHello", name_ti.text);
};
send_button.addEventListener("click", sendListener);
In the following example, the receiving SWF file, which resides in thisDomain.com, accepts
commands only from SWF files located in thisDomain.com or thatDomain.com:
var aLocalConn:LocalConnection = new LocalConnection();
aLocalConn.Trace = function(aString) {
aTextField += aString+newline;
};
aLocalConn.allowDomain = function(sendingDomain) {
return (sendingDomain == this.domain() || sendingDomain ==
"www.macromedia.com");
};
aLocalConn.connect("_mylc");
When published for Flash Player 7 or later, exact domain matching is used. This means that the
example will fail if the SWF files are located at www.thatDomain.com but will work if the files are
located at thatDomain.com.
