Hi,
In the last few days I built a bead MultipleFiles and ended up changing a
lot in FileReference.
The thing is that FileReference was designed in mind for a single file and
a lot of changes would be required.
This is a long task of rewriting a Flex application to Royale and there is
a single place that requires multiple files upload, so, I decide to
implement it directly with JS and not change the Royale Framework, avoiding
this complexity.
Of course, if in future this becomes more required (even for another user),
I can dive and implement it (perhave a browseForMultiple method instead of
a bead on this particular scenario and not change the original method).
Here my JS code only for this specific and singular use case:
var input:Element = document.createElement("input");
input.setAttribute("type", "file");
input.setAttribute("accept", "application/pdf");
input.setAttribute("multiple", true);
input.addEventListener("change", function():void
{
for (var i:int = 0; i < input["files"].length; i++)
{
var reader:FileReader = new FileReader();
reader["fileName"] = input["files"][i].name;
reader.addEventListener("load", function(e:Event):void
{
var fileName = e.target.fileName;
var fileData = btoa(e.target.result);
//do what necessary with file name and file data now with AS
});
reader.readAsBinaryString(input["files"][i]);
}
});
input.click();
}
