We have a large model and it takes a couple seconds for ng-repeat to bind all the items in the model to the form. We would like to show a spinner while it this is happening. Is there some event that fires when binding is complete so we know when to hide the spinner?

fireEvent = function(){ // This will only run after the ng-repeat has rendered its things to the DOM $timeout(function(){ $scope. $broadcast('thingsRendered'); }, 0); }; }); Note that this is only useful for functions you need to call one time after the ng-repeat renders initially.
But ng-repeat is not the right thing to use when you have large datasets as it involves heavy DOM manipulations. And you should consider using ng-repeat with pagination. You can consider using transclusion inside a custom directive, to achieve the behavior you are looking for without using ng-repeat.
AngularJS ng-repeat Directive The ng-repeat directive repeats a set of HTML, a given number of times. The set of HTML will be repeated once per item in a collection. The collection must be an array or an object. Note: Each instance of the repetition is given its own scope, which consist of the current item.
$first and $last It's common when using ng-repeat to add specific behavior to the first or last element of the loop, e.g. special styling around the edges. Instead, ng-repeat already supplies you with two ready boolean properties. $first is true for the first element, and $last is true for the last element.

Use ng-show on the spinner If you are using 1.2 use ng-if
<div ng-controller="Ctrl">
<div ng-show="complete">Complete={{complete}}</div>
<div class="thing" ng-repeat="thing in things" my-post-repeat-directive>
thing {{thing}}
</div>
</div>
In your directive use $last to determine if rendering is done and then change the variable that you have the ng-show/ngif defined on.
function Ctrl($scope) {
$scope.complete=false;
$scope.doComplete = function() {
$scope.complete = true;
}
$scope.things = [
'A', 'B', 'C'
];
}
angular.module('myApp', [])
.directive('myPostRepeatDirective', function() {
return function(scope, element, attrs) {
if (scope.$last) {
scope.$eval('doComplete()');
}
};
});
