AngularJS: Scroll to end of element after applying DOM changes - angularjs

Question

I have a simple list of items. I want to be able to scroll to the bottom of the element displaying the items whenever I add more items. I understood there is no way of hooking to the end of the $apply() function, so what might be my solution?
Here is a jsfiddle to illustrate my problem. after adding enough items, the ul element doesn't scroll to the bottom...

Answer 1

There's the very awesome angularjs-scroll-glue available, which does exactly what you want.
All you need to do is to apply the scroll-glue directive to your container element, and you get exactly what you're looking for.
There's also a demo available.

Another valid solution to this is using $timeout. Using a timeout value of 0, angular will wait until the DOM is rendered before calling the function you pass to $timeout. So, after you add an element to the list, you can use this to wait for your new element to be added to the DOM before scrolling to the bottom.
Like #Mark Coleman's solution, this won't require any extra external libraries.
var myApp = angular.module('myApp', []);
function MyCtrl($scope, $timeout) {
$scope.list = ["item 1", "item 2", "item 3", "item 4", "item 5"];
$scope.add = function() {
$scope.list.push("new item");
$timeout(function() {
var scroller = document.getElementById("autoscroll");
scroller.scrollTop = scroller.scrollHeight;
}, 0, false);
}
}
ul {
height: 150px;
overflow: scroll;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="MyCtrl">
<button ng-click="add()">Add</button>
<ul id="autoscroll">
<li ng-repeat="item in list">{{item}}</li>
</ul>
</div>
</div>

A simple working example (no need for plugins or directives)...
.controller('Controller', function($scope, $anchorScroll, $location, $timeout) {
$scope.func = function(data) {
// some data appending here...
$timeout(function() {
$location.hash('end');
$anchorScroll();
})
}
})
The trick that did it for me was wrapping the anchorScroll command with $timeout, that way the scope was resolved and it automatically shifted to an element at the end of the page.

You could create a simple directive that bind a click handler that scrolls the <ul> to the bottom each time.
myApp.directive("scrollBottom", function(){
return {
link: function(scope, element, attr){
var $id= $("#" + attr.scrollBottom);
$(element).on("click", function(){
$id.scrollTop($id[0].scrollHeight);
});
}
}
});

Answer 5

You can use the AnchorScroll.. here the documentation: https://docs.angularjs.org/api/ng/service/$anchorScroll

Answer 6

You can achieve this using angularjs custom directory.
example :
<ul style="overflow: auto; max-height: 160px;" id="promptAnswerBlock">
<li ng-repeat="obj in objectKist track by $index" on-finish-render="ngRepeatFinished">
app.directive('onFinishRender', function($timeout) {
return {
restrict : 'A',
link : function(scope, element, attr) {
if (scope.$last === true) {
$timeout(function() {
$('#promptAnswerBlock').scrollTop($('#promptAnswerBlock')[0].scrollHeight + 150);
});
}
}
}
});
</li>
