Home button should reset page

[tmheunis]

If I filter subdatasets by any means, and then I select the home button I would expect to reset the filtering options to default. Also, if I click the home button I would expect it to reset to the subdatasets tab, if I were originally on funding or content tabs.

Note to self about the functionality:

Home button calls router.push(params) and when Vue Router realises that the user is trying to navigate to the same route that is currently active, it throws an error:

I think the code should catch this redundant navigation attempt and call the necessary functionality.

Also, any refactoring of routing code should take into account route.push() and/or route.replace() for tab navigation, see #391.

The current idea is to run some logic in the goToHome() function on the dataset component, before navigation:

Current logic when pressing home button when located on any dataset page in a catalog:

If there is NO home page set:

• if there is a tab name in the URL, navigate to current
• else: don't navigate, only "reset"

If there IS a home page set:

• if the current page IS the home page:
  • if there is a tab name in the URL, navigate to current
  • else: don't navigate, only "reset"
• if the current page is NOT the home page, navigate to home

reset = clear filters and set tab index = 0
