元素中的角度ng-repeat条件包装项目（ng-repeat组中的过滤器项目）

Question

I'm trying to hide occupation name when filtered user is not found in some occupation.

JS:

$scope.contacts = [
    {name: 'John', occupation: 'occupation 1'},
    {name: 'George', occupation: 'occupation 2'},
    {name: 'Jeck', occupation: 'occupation 3'},
    {name: 'Paula', occupation: 'occupation 1'},
    {name: 'Scruath', occupation: 'occupation 3'}
];

HTML:

<input type="text" ng-model="query">
<div ng-repeat="(key, occupation) in contacts | groupBy: 'occupation'">
    <p ng-bind="occupation[0].occupation"></p>
    <div>
        <div ng-repeat="contact in occupation | filter:search">
            <p ng-bind="::contact.fullName"></p>
            <p ng-bind="::contact.email"></p>
        </div>
    </div>
</div>

RESULT:

Occupation Name: "occupation 1"

• name: "John"
• name: "Paula"

Occupation Name: "occupation 2"

• name: "George"

Occupation Name: "occupation 3"

• name: "Jeck"
• name: "Scruath"

Any thoughts?

Answer 1

There are two solution to your problem:

• Use ng-show on the filtered array.
• Use the sorting on the top ng-repeat .

Live example on jsfiddle .

 angular.module('ExampleApp', ['angular.filter']) .controller('ExampleController', function($scope) { $scope.contacts = [{ name: 'John', occupation: 'occupation 1' }, { name: 'George', occupation: 'occupation 2' }, { name: 'Jeck', occupation: 'occupation 3' }, { name: 'Paula', occupation: 'occupation 1' }, { name: 'Scruath', occupation: 'occupation 3' }]; });
