W3C/PhoneGapFileReader-如何使用？-W3C/PhoneGapFileReader-howtouse?

I am working with PhoneGap (which implements a W3C FileReader for its file access), and there are a ton of tutorials online, but they all seem to lead to a dead end. Basically, they show you how to set everything up, but in the end, they all get to a place where it says:

我正在使用PhoneGap（它为文件访问实现了W3C FileReader），并且有很多在线教程，但它们似乎都导致死路一条。基本上，它们会向您展示如何设置所有内容，但最终，它们都到达了一个地方：

myReader.readAsText(file);

What I am confused about is...what exactly does that do? Does it return some sort of index array? Can I use something along the lines of while(!feof)? How can I actually access what it has just read?

我感到困惑的是......究竟是做什么的？它是否返回某种索引数组？我可以使用while（！feof）的东西吗？我怎样才能真正访问它刚才读到的内容？

var reader = new FileReader();
reader.Onloadend= function(evt) {
    console.log("Read as data URL");
    console.log(evt.target.result);
};
reader.readAsText(file);
