javascript - AngularJS分页表: limitTo parameters do not update in the view

Question

我正在 AngularJS 中的 Bootstrap 3 表中显示 JSON。

我正在使用 limitTo 过滤器对表格进行分页:

var root = 'https://jsonplaceholder.typicode.com';

// Create an Angular module named "usersApp"
var app = angular.module("usersApp", []);

// Create controller for the "usersApp" module
app.controller("usersCtrl", ["$scope", "$http", function($scope, $http) {
  var url = root + "/users"
  $http.get(url)
    .then(function(data) {
      // Users arary
      $scope.users = data.data;

      // Order by function
      $scope.orderByMe = function(criteria) {
        $scope.myOrderBy = criteria;
      }

      // Paginate
      $scope.pageNum = 1;
      $scope.perPage = 5;
      $scope.startAt = 0;

      $scope.prevPage = function() {
        if ($scope.pageNum > 1) {
          $scope.pageNum = $scope.pageNum - 1;
          $scope.startAt = ($scope.pageNum - 1) * $scope.perPage;
        }
      };

      $scope.nextPage = function() {
        $scope.pageNum = $scope.pageNum + 1;
        $scope.startAt = ($scope.pageNum - 1) * $scope.perPage;
      };

    });
}]);

body {
  padding-top: 70px;
}
.container {
  padding: 0 10px;
}
.search-box {
  margin: 5px;
}
.panel-heading {
  font-weight: bold;
}
.table-container {
  margin: 10px 0;
}
.table-container .panel-body {
  padding: 0;
}
.table-container table {
  margin-bottom: 0;
  border-width: 0;
  border-top-width: 1px;
  border-bottom-width: 1px;
}
.table-container table tr:last-child td {
  border-bottom: none;
}
.table-container table tr th {
  font-weight: bold;
  cursor: pointer;
}
.table-container table tr th:first-child {
  border-left: none;
}
.table-container table tr td:first-child {
  border-left: none;
}
.table-container table tr th:last-child, .table-container table tr td:last-child {
  border-right: none;
}

@media (min-width: 768px) {
  .container {
    width: auto;
  }
}

                </tr>
              </tbody>
            </table>
          </div>
          <p class="text-center">Page {{pageNum}}</p>
          <p class="text-center">Show users from {{startAt + 1}} to {{startAt + perPage}}</p>
          <div class="text-center">
            <ul class="pager">
              <li><a href="#" ng-click="prevPage()">&larr; Previous</a></li>
              <li><a href="#" ng-click="nextPage()">Next &rarr;</a></li>
            </ul>
          </div>
        </div>
      </div>
    </div>
  </div>

单击下一步和上一步按钮后，limitTo的startAt参数执行 在 View 中更新，如表下面的段落所示，但 data-ng-repeat 不会(重新)使用它更新。

如何在每次更新 startAt 时呈现表格？ 我的脚本中缺少什么？

Answer 1

1.2.23在limitTo中没有begin，我发现支持begin的最低版本是1.4.0

这是一个可以工作的小工具。 https://plnkr.co/edit/bcrlKW46zlZ20k6E57M4
