Access member method from async call


This question already has an answer here:


I suppose your readerOnLoad function is called in a different context than you expect, and you end up with a this value which is not an instance of FileProcessor.

Try this:

reader.onload = this.readerOnload.bind(this);

Or, if you must support older browsers:

var self = this;
reader.onload = function(e) { self.readerOnLoad(e); };
