[javascript] How do I pass the this context to a function?

Another basic example:

NOT working:

var img = new Image;
img.onload = function() {
   this.myGlobalFunction(img);
};
img.src = reader.result;

Working:

var img = new Image;
img.onload = function() {
   this.myGlobalFunction(img);
}.bind(this);
img.src = reader.result;

So basically: just add .bind(this) to your function
