[annotator-dev] Loading Annotations Asynchronously

Sun Jan 26 00:04:52 UTC 2014

Hey Randall,

Sure. I set up the annotator, then get a reference to it with:

var subscriber = $('#textcontent').annotator().data('annotator');

Then I define an on click function for a filter control, which sets up a loadOptions object, and calls:

subscriber.plugins.Store.loadAnnotationsFromSearch(loadOptions);

That works, in that the data are correctly loaded from the API. What’s not happening, is that the annotator doesn’t reload the new annotations in the DOM, and/or the highlights are not shown in the text. 

Is there another step the annotator takes after loading or loading from search, to display or update display of highlights?

Here’s the relevant line: https://github.com/hyperstudio/Annotation-Studio/blob/master/app/views/documents/_annotator-setup.html.erb#L181

Thanks!

Jamie
