$scope.call= function(){
alert('reached end');
};
})
.directive('ul', function () {
return {
restrict: 'E',
link: function ($scope, element, attrs) {
element.bind('scroll', function (e) {
if ($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight) {
// alert('end reached');
$scope.call();
}
})
}
}
});
But in the above try $scope.call();
function is not calling. Any one pls help me
My actual requirement is when the scroll reaches the end, remaining records has to show in the typeahead
Make these changes to your directive, add a callBack scope variable in directive and add a callBack attribute in HTML , type function
.directive('ul', function () {
return {
restrict: 'E',
scope: {
callBack:"&"
}
link: function (scope, element, attrs) {
scope.callBack();
})
}
}
<div ul callBack="functionName"></div>
