lrInfiniteScroll

lrInfiniteScroll is a module for AngularJS which allow you to attach an event handler to the element when this element has been scrolled almost to its bottom. In most of the case it will be used for infinite scrolling. It is very light (about 45 lines of code) and optimized to reduce the amount of $digest loop.

See the example section.

Attach an Event Handler

Simply set as attribute a function accessible within the $scope:

<ul lr-infinite-scroll="myEventHandler">
    <li ng-repeat="item in myCollection">
</ul>

Change the Scroll Threshold

By default the handler will be called when the user is scrolling down and only 50 pixels are remaining before reaching the end of the element. You can overwrite the 50px by setting the attribute scroll-threshold:

<ul lr-infinite-scroll="myEventHandler" scroll-threshold="200">
    <li ng-repeat="item in myCollection">
</ul>

Change the Time Threshold

To reduce the amount of $digest loop, instead of calling the handler whenever a scroll down event is detected in the end zone a timer is started and if no other event is detected within 400ms, then the handler is called.

You can overwrite the time value by setting the time-threshold attribute:

<ul lr-infinite-scroll="myEventHandler" scroll-threshold="200" time-threshold="600">
    <li ng-repeat="item in myCollection">
</ul>
