bonjour.
sur mon site, l'utilisateur peut "signer" dans un blob mais.. ensuite je voudrais enregistrer ce blob directement sur le serveur sans aucune boite de message et.. n'y arrive pas..
une partie du code :
save : function(){
//
var canvas = document.getElementById("newSignature");
var dataURL = canvas.toDataURL("image/png");
document.getElementById("saveSignature").src = dataURL;
//window.alert('fin save');
canvas.toBlob(function (blob)
{
var nouvelleImg = document.createElement("img"),
url = URL.createObjectURL(blob);
});
nouvelleImg.src = "image.jpg";
nouvelleImg.canvas.save;
nouvelleImg.savefile("./test.jpg");
nouvelleImg.canvas.URL="http://www.xxxxxxxxxxxxxx.fr/site/protect/signature.png"
nouvelleImg.writeFile();
nouvelleImg.save;
et rien ne fonctionne..
Je débute en javascript.. Merci
