Using the "loading remote data" example from the ngInfiniteScroll website I have tried to implement infinite scrolling. My issue;
The function nextPage()
gets called continuously until there are no more records left to load (controlled by an offset value in the SQL query).
I'd appreciate any input on this as I'm rather lost.
Thanks in advance.
HTML
<tbody>
<div id="infinite_scroll" infinite-scroll='visits.nextPage()' infinite-scroll-disabled='visits.busy' infinite-scroll-distance='1'>
<tr ng-repeat="visit in visits.items" ng-class="{active: visit.uuid == data.detailItem.uuid}" ng-click="openDetailItem(visit.uuid)">
<td>{{visit.details.name}}</td>
<td>{{visit.created_at}}</td>
</tr>
</div>
</tbody>

angular.module('app').factory('Visits', function(VisitResource) {
// new visits object
var Visits = function () {
this.items = [];
this.busy = false;
this.offset = 0;
};
Visits.prototype.nextPage = function () {
// busy - stop
if (this.busy == true) {
// DEBUG
console.log('busy test 1.1: ' + this.busy);
return;
} else {
// DEBUG
console.log('busy test 1.2: ' + this.busy);
}
// busy now
this.busy = true;
VisitResource.getVisitations({
limit: 500,
offset: this.offset
}, function (response) {
// stop loading if no data returned
if(response.data.length == 0) {
// DEBUG
console.log('busy test 2: ' + this.busy);
return;
} else {
// DEBUG
console.log('Payload: ' + response.data.length);
}
var _this = this;
angular.forEach(response.data, function (a_visit) {
_this.items.push(a_visit);
});
// set the last acquired record value
this.offset = this.items[this.items.length - 1].id;
// not busy
this.busy = false;
}.bind(this));
};
return Visits;
});
As it turns out you can't get vanilla nginfinitescroll to trigger when the container is scrolled as nginfinitescroll is looking at the height of the window.
