Question

在某些职业中找不到过滤后的用户时，我试图隐藏职业名称。

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>

结果：

职业名称：＆＃34;职业1＆＃34;

姓名：＆＃34; John＆＃34;
姓名：＆＃34; Paula＆＃34;

职业名称：＆＃34;职业2＆＃34;

姓名：＆＃34; George＆＃34;

职业名称：＆＃34;职业3＆＃34;

姓名：＆＃34; Jeck＆＃34;
姓名：＆＃34; Scruath＆＃34;

有什么想法吗？

您的问题有两种解决方案：

在已过滤的阵列上使用ng-show。
使用顶部ng-repeat的排序。

jsfiddle上的实例。

＆＃13;

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'
    }];
  });
