Original Post Discovery minimal client side implementation. Requires promisejs (HTTP) and bean (events)

opd.js

// Original post discovery (in progress)
var noteForms = document.querySelectorAll('.note-post-form');
if (noteForms.length > 0) {
	for (var i = 0;i < noteForms.length;i++) {
		var form = noteForms[i];
		var inReplyToField = form.querySelector('.in-reply-to');
		bean.on(inReplyToField, 'blur', function(event) {
			var url = event.target.value;
			// TODO: Start loading indicator
			promise.get('/services/original-post', {'url': url}).then(function (error, text, xhr) {
				// TODO: Stop loading indicator
				if (error) return;
				
				inReplyToField.value = text;
			});
		});
		if (inReplyToField.value !== '')
			bean.fire(inReplyToField, 'blur');
	}
}
