javascript - Angularjs ng-repeat 与过滤范围对象

Question

我需要过滤 ng-repeat 中的行基于 $scope.filterObject 中的内容。我有一个数据在 $scope.customerData包含所有客户信息，但是当循环每个客户时，我只想根据 $scope.filterObject 中的内容显示结果。例如，仅显示具有 $scope.filterObject 中职位的客户行.

这是 JSFiddle link .

这是我到目前为止所拥有的:

HTML:

<table ng-app="app" ng-controller="AppsCtrl">
  <thead>
    <tr>
      <th>+</th>
      <th>Name</th>
      <th>Email</th>
      <th>DOB</th>
      <th>Hobby</th>
    </tr>
  </thead>
  <tbody ng-repeat="customer in customerData">
    <tr>
      <td><a href="#" class="main" ng-click="expandTable($event)">+</a></td>
      <td>{{customer.name}}</td>
      <td>{{customer.email}}</td>
      <td>{{customer.DOB}}</td>
      <td>{{customer.Hobby}}</td>
    </tr>
    <tr class="showhide">
      <td> </td>
      <td>Degree</td>
      <td>{{customer.Degree}}</td>
      <td>Job title</td>
      <td>{{customer.Job}}</td>
    </tr>
    <tr class="showhide">
      <td></td>
      <td>Country</td>
      <td>{{customer.Country}}</td>
      <td>City</td>
      <td>{{customer.City}}</td>
    </tr>
  </tbody>
</table>

JS:

// AngularJS toggle table

var app = angular.module('app', []);
app.controller('AppsCtrl', function($scope) {
  $scope.expandTable = function() {
    console.log($(event.target).closest('tr').nextUntil("tr.main"));
    $(event.target).closest('tr').nextUntil("tr.main").slideToggle();
    // console.log($(event.currentTarget).parent().parent());
  }
  var data = [{
    "name": "John",
    "email": "JSmith@yahoo.com",
    "DOB": "01/05/1968",
    "Degree": " BSC",
    "Job": "Engineer",
    "Hobby": "Football",
    "Country": "US",
    "City": "Houston"
  }, {
    "name": "Jessica",
    "email": "Jess@yahoo.com",
    "DOB": "03/05/1976",
    "Degree": " Accounting",
    "Job": "CPA",
    "Hobby": "Video games",
    "Country": "US",
    "City": "Fredericks"
  }, {
    "name": "Andrew",
    "email": "AJoan@yahoo.com",
    "DOB": "06/12/1998",
    "Degree": " PHD",
    "Job": "Professor",
    "Hobby": "Writing",
    "Country": "US",
    "City": "San Diago"
  }, {
    "name": "Rich",
    "email": "Rschol@yahoo.com",
    "DOB": "09/21/1988",
    "Degree": " PHD",
    "Job": "Technician",
    "Hobby": "Writing",
    "Country": "US",
    "City": "San Diago"
  }];
  $scope.customerData = data;
  $scope.filterObject = [{
    "Job": "CPA"
  }, {
    "Job": "Engineer"
  }]
});

\非常感谢任何建议和帮助。 :)

您可以使用 Angular filter ng-repeat 中的函数将 customerArray 与 customerObject 进行比较，然后仅返回与 customerObject 属性匹配的元素。

//Instead of array    
$scope.filterObject = {
    "Job": "CPA"
  };

HTML:

  <tr ng-repeat="customer in customerData | filter: filterObject">

否则，您可以创建自定义过滤器函数来比较字段或字段数组:

 app.filter('customerFilter', function() {
  return function( items, filterParams) {
    var filtered = [];
    angular.forEach(items, function(item) {
      if(filterParams.Job.indexOf(item.Job) !== -1) {
        filtered.push(item);
      }
    });
    return filtered;

}；});

HTML:

   <tr ng-repeat="customer in customerData | customerFilter: filters">

客户 Controller :

$scope.filters = {
  "Job" :["Technician","CPA"]
  }
