Hi,
I try to upload the content of my html5 canvas
here what it's my javascript look like :
function saveImage() {
var canvasData = canvas.toDataURL();
var ajax = new XMLHttpRequest();
ajax.open("POST",'localhost/getFile.fwx',false);
ajax.onreadystatechange = function() {
console.log(ajax.responseText);
}
ajax.setRequestHeader('Content-Type', 'application/upload');
ajax.send("imgData="+canvasData);
}

It's a .PNG encoded base64, I try to get it from my getfile.fwx foxweb script but can't get it!?
can you help me with getfile.fwx to recuperate this images?
do you have some code I can re-use?
thank you
