I cannot seem to scroll to the last message in my chat window.
var app=angular.module('myApp', ['ngMaterial'] );
app.controller('ChatCtrl', function($window, $anchorScroll){
var self = this;
self.messageWindowHeight = parseInt($window.innerHeight - 170) + 'px';
self.messages = [];
for(var i = 1 ; i<=200;i ++){
self.messages.push(i);
}
self.user = { text : ""};
self.send = function(){
self.messages.push(angular.copy(self.user.text));
self.user.text = "";
}
});
app.directive('scrollToBottom', function($timeout, $window) {
return {
scope: {
scrollToBottom: "="
},
restrict: 'A',
link: function(scope, element, attr) {
scope.$watchCollection('scrollToBottom', function(newVal) {
if (newVal) {
$timeout(function() {
element[0].scrollTop = element[0].scrollHeight;
}, 0);
}
});
}
};
});/* Styles go here */
