angular-in-viewport

Set of directives handling events when a DOM element enters or leaves a viewport

viewport

Directive (attribute) specifying the DOM element which should be used as viewport.

To use window as the viewport element, set viewport="window" on any parent element.

viewport-enter

Directive (attribute) specifying a DOM element which should be watched. When the element enters the viewport the value of the attribute will be evaluated.

viewport-leave

Directive (attribute) specifying a DOM element which should be watched. When the element leaves the viewport the value of the attribute will be evaluated. The viewport-leave attribute needs a viewport-enter attribute with valid callback

#Compatibility This plugin works with Angular 1.x (v1.2 and higher)

Viewport container element:

<ul style="width: 200px; height: 200px" viewport>
  <li ng-repeat="item in items" style="width: 200px; height: 200px" viewport-leave="item.visible = false" viewport-enter="item.visible = true">
</ul>
