Wrong behavior after the first file read #29
Description
Hi,
When I read from the input file the first time, everything is correct, but when the file is changed and I read again, the load event will be triggered 2 times, when I change the file again, it's getting triggered 3 times, and so on... This is obviously wrong, the real Filereader object doesn't behaves like this.
Here are some logs :
debugMode : ,true
File Input add...,my_input_id,false,,,
MouseOverEvent...,my_input_id
FileInput Event click[object Object]
Browsing...,my_input_id
File Input change...,my_input_id
FileInput Event change[object Object]
FileReader read...,my_input_id,A.JPG,readAsDataURL
FileReader Event loadstart[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event load[object Object]true
FileReader result...,my_input_id.A.JPG
FileReader Event loadend[object Object]true
FileInput Event click[object Object]
Browsing...,my_input_id
File Input change...,my_input_id

FileReader Event loadstart[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event progress[object Object]true
FileReader Event load[object Object]true <====== WRONG FROM HERE
FileReader result...,my_input_id.A.JPG
FileReader Event loadend[object Object]true <=== TO HERE
FileReader Event load[object Object]true
FileReader result...,my_input_id.B.jpg
FileReader Event loadend[object Object]true

Occurs for me as well. Would love a fix.

@MattKing17 : here is the dirty hack I've done for now (bamarni@74546ba).
I didn't go further in my investigation since it fixed my issue, I'm not sure though wether the issue is in this library or on the underlying swfObject it uses.

thanks @bamarni! I'm trying to remove all dependencies on jquery from this plugin and ended up rewriting an implementation myself. I think what I'm going to do is refactor it to only support one file handler at a time. It seems that the reader result comes in multiple times, it ends up triggering load events for all file handlers ever registered. This works for my case since I only care about people uploading one file at a time.
