[annotator-dev] Custom Storage Plugin

Fri Jul 31 14:04:28 UTC 2015

Hi,

I am writing my own storage backend in PHP and also a JavaScript plugin to
send/retrieve the data to the server. I don't want to use the default store
plugin.

I have subscribed to the "beforeAnnotationCreated" event. When it is fired,
I attach the url to the annotation. I have also subscribed to the
"annotationCreated" event. When it is fired, I attempt to send to
annotation to the server via Ajax. However I get the following error:
*Uncaught Error: Error while finding start node: undefined: TypeError:
Cannot read property 'substring' of undefined.*

It seems to me that the annotation object is no longer available. I have
attached the code below (hopefully the format doesn't get messed up).
I appreciate any help!

Annotator.Plugin.Storage= function(element) {
        return {
            pluginInit: function() {
                this.annotator
                    .subscribe("beforeAnnotationCreated",
function(annotation) {
                    annotation.url = document.location.href;
                    })
                    .subscribe("annotationCreated", function(annotation) {
                    console.log("Created: %o", annotation); //This works as
expected

                    jQuery.post("./annotator/create.php", annotation,
function(data) {
                    annotation.id = data.id;
                    annotation.username = data.username;
                    annotation.timecreated = data.timecreated;
                    }); //This doesn't work
                    })
            }
        }
    };
