Overview

We automatically run JavaScript in the included file.

Details

We include a JS file:

<script src="../Scripts/AutoRun.js" type="text/javascript"\>\</script>

And inside it we execute JavaScript:

document.write("\<p\>JavaScript text run automatically\</p\>");

The point is that arbitrary JavaScript is run without us ever explicitly calling it. This can be useful or dangerous, depending on how it is used.
