How can one access this completely anonymous entity, and is there a way to identify it?

Understanding the Purpose of a Script Tag with src and Content

While browsing through this webpage that explains how to include Google's +1 button, I came across an example code snippet that caught my attention:

<script type="text/javascript" src="https://apis.google.com/js/plusone.js">
  {parsetags: 'explicit'}
</script>

At first glance, it appears to be an anonymous object. However, I'm unsure how this anonymous object can be accessed or utilized. My initial thought was to parse the DOM, but that seems overly complex.

Is the code indeed showcasing an anonymous object, and if so, how is it used? Could there be a common technique that I am overlooking?

Alternatively, could I be misinterpreting the code entirely, and it's not an anonymous object at all?

Answer №1

This is a sneaky workaround.

When a script element contains a src attribute, the content within the element is disregarded.

The JavaScript code tries to locate its own script element, extract the content inside it (most likely using innerHTML, although not confirmed), and then interpret it.
