See this blog post:

but that is in Java, does not cover Robot Framework and Selenium2Library, but the concepts can be adapted. Using that example, it is probably easier to adapt with the Java version of the Selenium2Library rather than Python.

This that I mention of course is for the unseen javascript errors or ones that pop up an error on IE (but usually only show up in javascript console for other browsers). This does not apply to special alert/confirmation popups indicating an error or question to proceed/cancel to the user, which are not "javascript" errors but javascript prompts/alerts.

If you are continuosly getting js error then use "Get Alert Message" or "Alert should be present" commands.

Didn't you see my previous comment/post? That gives you a link to the details. You have to port it to RobotFramework, because I haven't heard of anyone ported it already.

Shouldn't be a lot of work to port. Just execute some javascript with Selenium2Library on every page you test, or for Firefox, load the special extension XPI file mentioned in that link, then later after testing a page, call some special javascript to retrieve errors if any, there are some snippet examples in that link page, although I don't think any are in RobotFramework/Python.
