smartupload.js

Upload lib in js, simple and smart :

var smartUp = new SmartUpload("inputFileId", "http://target/upload.php");

The SmartUpload object handle the file input selection, and send chunk of file to the server.

You can add events/cb easily :

smartUp.updateProgress = function(){ /* DO SOMETHING HERE */ };

Or change chunks size, method and send data synchronously:

smartUp.smartSize = 1024 * 100; //100 Ko DEFAULT => 128Ko
smartUp.smartMethod = "PUT"; // DEFAULT => "POST"
smartUp.smartAsync = true; // DEFAULT => false
smartUp.smartTimeout = 5000; // DEFAULT => 1000 in ms

Format

Chunks of data are sent with POST method, with multipart/form-data enctype. the result is a POST Object :

• data -- the chunk of data in binary format
• id -- the id of the file (== filename)
• type -- the mimeType of the file
• chunkIndex -- the chunk index, begin at 0
• chunkLength -- the length of chunk sent
• chunkStart -- the start of chunk sent in the file
• chunkTotal -- the length of the file

Server

The server must return a JSON object with at least this field :

{
  code:0
}

If code != 0, an error occured and smartupload.js will try to reupload the chunk after the smartTimeout delay.
