Sometimes, one cannot inspect JavaScript-objects using an external debugger, like Firebug.

For example, this can happen during development of Firefox addons: Open the JavaScript inspector of Firebug and you will only see the JavaScript errors on the currently displayed website, but not the ones from the addon.

Thus, I modified the inspect()-function from Ariel Tapia (codeprojects.com) a bit. My version will not only return a HTML string with all the attributes and functions that are inside the object. It will also add the values of these.

Installation: Just unzip the file and include it via
<script src="inspector.js" type="text/javascript"></script>
(As an alternative, you can also just copy and paste the function directly into your source.)

Example usage: var htmlResult = inspect(myObject, null, null);
htmlResult will now hold a string-representation of the properties and functions of myObject.

Note: An alternative for Firefox addons is Venkman. Haven’t really figured out how to use that though.
So, if you don’t want to bother with Venkman or need an object-inspector for any other purpose, I think you’ll be fine with my function provided above.
