Can you explain the significance of the equals sign in the ng-repeat attribute value?
<li ng-repeat="person in people = (people | orderBy: firstname)">
rather than using:
<li ng-repeat="person in people | orderBy: firstname">
I couldn't find any examples illustrating this in the ngRepeat documentation.
This is a helpful tool for calculating the number of filtered objects.
function Users($scope) {
$scope.users = [{
username: 'john'
}, {
username: 'doe'
}, {
username: 'jane'
}, {
username: 'smith'
}]
}<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="Users">
<ul>
<li ng-repeat="user in filteredUsers = (users | filter: 'j')">{{user.username}}</li>
</ul>
Total filtered items: {{ filteredUsers.length }}
</div>Hey @Krzysztof, using the "=" operator is not necessary to display the number of filtered objects. It can be achieved without it. Therefore, your assertion is incorrect.
