如何在angularjs中更新数组列表对象

Question

我是AngularJS的学习者，我试图更新我的表列表用户，使其能够编辑用户信息，并能编辑下面的代码使用的表列表对象，但是在保存编辑用户信息时出现异常。

employee_list.html

<?php $numrows = count( get_sub_field( 'agence_post' ) );
  echo $numrows;?>

EmployeeListController

<div ng-repeat="employee in employeeList | filter:{name:searchName}">
    <div class="panel panel-primary" ng-class="{'panel-success':employee.id==selectedId}">
        <div class="panel-heading">
            <h3 class="panel-title">{{employee.name}}</h3>
        </div>
        <div class="panel-body">

            <div class="row">

EmployeeCreateCtrl

 $scope.employeeList = employeeService.getListOfEmployees();

employeeService：

     */
    $scope.saveData = function (employee) {
        //Edit employee Information
        if ($stateParams.employeeId != 0) {
            var employee = employeeService.getEmployeeById($stateParams.employeeId);
            employeeService.updateEmployee($stateParams.employeeId,employee);
        } else {
            employee.id = employeeService.getListOfEmployees().length + 1;
            employeeService.addNewEmployee(employee);
        }
        $state.go('employeeList');
    }

Answer 1

当要传递给“ ng-repeat”指令的数组中有重复对象时，AngularJS会引发上述异常。因此，您需要使用track by，如下所示。您可以在模型数组对象中使用track by $index或其他任何属性（例如track by employee.id或track by employee.email），这是唯一的。
试试下面的示例

<div ng-repeat="employee in employeeList | filter:{name:searchName} track by $index ">
