Question

我正在尝试使用php和angular从我的“Customers”表中删除一行。这是我得到的错误

“无法读取未定义的属性'拼接'。

有人知道为什么吗？

这是我的代码：

控制器：

$scope.delete = function(deletingId, index) {
        var params = $.param({"customer_id":deletingId});
        $http({
          headers: {'Content-Type': 'application/x-www-form-urlencoded'},
          url: 'http://localhost:8081/hamatkin/api/delete-customer.php/',
          method: "GET",
          data: params
        }).success(function(data){
         console.log(data);
         $scope.customerDetails = data;
         $scope.customerDetails.splice(index, 1);
        });
      }

Customer.php

<?php
class Customer {

  private $table_name = "customers";

  public $customer_id;
  public $kind_Of_Customer;
  public $full_name;
  public $id;
  public $city;
  public $address;
  public $phone;
  public $phone_2;
  public $email;
  public $fax;
  public $referrer;
  public $comments;


}

?>

删除-customer.php

<?php header('Content-Type: text/html; charset=utf-8');
$connect=mysqli_connect("localhost", "root", "", "hamatkin");

  include_once 'Customer.php';

// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$customer = new Customer();


if(isset($_GET['customer_id'])){
   $customer_id = $_GET['customer_id'];
   $del = "DELETE FROM posts WHERE customer_id='".$customer_id."'";
   mysql_query($connect, $del);
 }


$newURL = "/hamatkin/#/customerCards";
header('Location: '.$newURL);
?>

HTML

<tr ng-repeat="x in customers | filter:search_query | orderBy: order_query:reverse_query">
            <td>{{ x.customer_id}}</td>
            <td>{{ x.kind_Of_Customer}}</td>
            <td>{{ x.full_name}}</td>
            <td> {{ x.id}} </td>
            <td> {{ x.city}} </td>
                     <td><a href="/hamatkin/index.html#/customerCardDetails/{{ x.customer_id}}"  class="btn btn-primary btn- active">הצג פרטי לקוח </a></td>
            <td><a ng-click="delete(x.customer_id, $index)" class="btn btn-primary btn- active">מחיקה</td>

当我使用console.log（数据）

时

Answer 1

$scope.data未定义，因此错误。它应该是，

.success(function(data){

          data.splice(index, 1);
          $scope.customerDetails = data;

        });

或者，

.success(function(data){
          $scope.customerDetails = data;
          $scope.customerDetails.splice(index, 1);
        });

如果数据不是数组，则无效。

我想它应该是，

.success(function(data){
          console.log(data);

          $scope.customerDetails = data.data;
          $scope.customerDetails.splice(index, 1);
        });

Answer 2

这意味着您的$scope.data未定义。在进行拼接之前，请检查$scope.data是否有值并且是否为数组。

另外，我在代码中看不到$scope.data。您在回调中获得的data可能是您需要拼接的那个。

Answer 3

$ scope.data未定义为什么它会抛出该错误仅使用数据

data.splice(index, 1);

无法读取未定义错误的属性“拼接”
