Availability
Flash Player 6.
Usage
my_lv.getBytesLoaded() : Number
Parameters
None.
Returns
An integer.
Description
Method; returns the number of bytes downloaded by LoadVars.load() or
LoadVars.sendAndLoad(). This method returns undefined if no load operation is in progress
or if a load operation has not yet begun.
Example
The following example uses a ProgressBar instance and a LoadVars object to download a text file.
When you test the file, two things write to the log file: whether the file loads successfully and how
much data loads into the SWF file. You must replace the URL parameter of the
LoadVars.load() command so that the parameter refers to a valid text file using HTTP. If you
attempt to use this example to load a local file that resides on your hard disk, this example will not
work properly because in test movie mode Flash Player loads local files in their entirety. To see this
code work, add a ProgressBar instance called
loadvars_pb to the Stage. Then add the following
ActionScript:
var loadvars_pb:mx.controls.ProgressBar;
var my_lv:LoadVars = new LoadVars();
loadvars_pb.mode = "manual";
this.createEmptyMovieClip("timer_mc", 999);
timer_mc.onEnterFrame = function() {
var lvBytesLoaded:Number = my_lv.getBytesLoaded();
var lvBytesTotal:Number = my_lv.getBytesTotal();
if (lvBytesTotal != undefined) {
trace("Loaded "+lvBytesLoaded+" of "+lvBytesTotal+" bytes.");
loadvars_pb.setProgress(lvBytesLoaded, lvBytesTotal);
}
};
