visaplan.plone.ajaxnavigation

Add AJAX navigation to a Plone site.

This is probably not the most advanced or state-of-the-art way to add AJAX navigation; for Plone 5, I was told about plone.patternslib, based on patternslib.

For Volto sites, the whole jQuery-based handling might be obsolete because of the use of React.js.

At the time of this writing, those were no options for me since I was still on Plone 4.3. Thus, I needed a working solution. Depending on the quality, I'll switch to some Plone-5-ish solution when doing the leap, or I'll stick with my own.

The general idea is:

  • Catch the onclick event for every a element on the page.

  • For some links, a special check will tell to proceed with the standard behaviour, i.e. load the target the standard way; this includes:

    • Link targets outside of the current site (another hostname is given)
    • Management pages (e.g. starting with manage_)
    • Other pages which don't load the navigation links etc. anyway, or wouldn't work when loaded via AJAX
    • Anchor elements with certain attributes
    • Views for contexts which don't have a suitable embedable view yet.

    For such link targets, this function will simply return true, and the page is loaded in the standard way.

  • If that check function says, "let's load the target via AJAX", it will look for certain elements on the page and try to update them:

    • content
    • breadcrumbs
    • title

    It will also set the page url accordingly, allowing for the browser history.

Features

  • Can be bullet points
