How do I implement progressive loading of content as you scroll down the page? Otherwise 1000 images would load at the same time.
I didn't want to use ngInfiniteScroll the other guy posted as my mobile app does not use jQuery so there is no point in loading it just for this.
Anyhow, I found a jsfiddle with pure Javascript that solves this problem.
HTML
<div id="fixed" when-scrolled="loadMore()">
<ul>
<li ng-repeat="i in items"></li>
</ul>
</div>
JavaScript
function Main($scope) {
$scope.items = [];
var counter = 0;
$scope.loadMore = function() {
for (var i = 0; i < 5; i++) {
$scope.items.push({
id: counter
});
counter += 10;
}
};
$scope.loadMore();
}
angular.module('scroll', []).directive('whenScrolled', function() {
return function(scope, elm, attr) {
var raw = elm[0];
elm.bind('scroll', function() {
if (raw.scrollTop + raw.offsetHeight >= raw.scrollHeight) {
scope.$apply(attr.whenScrolled);
}
});
};
});
