Some pages with AJAX should update quickly, because the data is likely
to be changing quickly, and be finished changing sooner. Other pages we
want to have tick over a bit slower.
This commit adds an optional ‘interval’ parameter to the updateContent
modules, which sets how often the page should ping the server for an
update.
It then sets the interval for the dashboard page to be 10 seconds,
rather than the default 1.5 seconds.
This is a first go at having the job page update without refreshing.
The approach I’ve taken is to do all the rendering of HTML on the server side,
rather than use a Javascipt templating engine like mustache. This ensures that
we don’t have to maintain two sets of templates.
So the approach is to split the job page into partials. These partials can then:
- be included in the job page to render the whole page
- be rendered indivudually and then returned as a blob of HTML inside a JSON
response
Then I’ve added a Javascript module which looks for areas of the page that should
be reloaded. For each area of the page it will poll a URL and re-render that
section of the page when it gets new HTML. It implements some throttling so that
API calls will never happen more frequently than 0.67 times/second.
