角ng-在元素中重复条件包装项(ng-重复组中的筛选项)

Question

当在某些职业中找不到过滤用户时，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：“职业1”

• 姓名：“约翰”
• 姓名：“保拉”

职业名称：“职业2”

• 姓名：“乔治”

职业名称：“职业3”

• 姓名："Jeck“
• 名称：“斯克鲁斯”

有什么想法吗？

对您的问题有两种解决方案：

• 对筛选后的数组使用ng-show。
• 使用顶部ng-repeat上的排序。

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'
    }];
  });
