I have a text file stored on the server and an object in HTML like this:

```
<object id="data" type="text/plain" data="test.txt"></object>

```

How can I read the contents of `test.txt` in Javascript? What I have so far is:

```
var data = document.getElementByID("data");

```

But I can't figure out how to read the HTML document inside the object tag.
