ActionScript Language Reference

When implementing onData( ), be sure to convert the loaded variables to properties via

decode( ), as shown in the following Example.

Example

The following example shows how to display raw loaded-variable source while preventing

it from being parsed by ActionScript. The onLoad( ) method is not called, and the

loaded

property is not set:

loadedVars = new LoadVars();

loadedVars.onData = function (src) {

trace("Variables received: " + src);

};

loadedVars.load("http://www.thesite.com/cgi-bin/getData.pl");

Here we display raw loaded-variable source but call onLoad( ) as it normally would be.

Note that we take care to recreate all the default onData( ) behavior, including converting

the loaded variables to properties with decode( ) and setting the

loaded property to true:

loadedVars = new LoadVars();

loadedVars.onData = function (src) {

trace("Variables received: " + src);

if (src = = undefined) {

this.onLoad(false);

} else {

this.decode(src);

this.loaded = true;

this.onLoad(true);

}

};

loadedVars.onLoad = function (success) {

trace("Vars load successfully? " + success);

}

loadedVars.load("http://www.thesite.com/cgi-bin/getData.pl");
