【问题标题】：Cannot read property 'splice' of undefined error无法读取未定义错误的属性“拼接”
【发布时间】：2016-07-25 06:19:33
【问题描述】：

我正在尝试使用 php 和 angular 从“客户”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：

控制者：

$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);
        });
      }

客户.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(data)

【问题讨论】：

标签： php angularjs

【解决方案1】：

这意味着您的$scope.data 未定义。在拼接之前检查$scope.data 是否有一个值并且是一个数组。

另外，我在您的代码中没有看到$scope.data。你在回调中得到的data 可能就是你需要拼接的那个。

【讨论】：

谢谢，我更改了代码，我有不同的错误 $scope.customerDetails.splice is not a function
表示 $scope.customerDetails 不是数组。你能在$scope.customerDetails 上做一个console.log 吗？
你的意思是console.log($scope.customerDetails)吗？写在哪里？
是的。在您的应用中打印并将输出发布到您的问题
好的，所以数据是 string 。 Splice 用于数组，它不适用于字符串

【解决方案2】：

$scope.data 未定义，这就是它抛出该错误的原因只使用数据

data.splice(index, 1);

【讨论】：

谢谢，我改成了@Ved 所说的，现在我有错误 - $scope.customerDetails.splice 不是函数
要么你无法获取数据，要么你获取的数据不是数组，所以你最好先记录数据。
你正在获取整个页面而不是你得到的数据，尝试链接到后端而不是 php 页面。

【解决方案3】：

$scope.data未定义，因此出现错误。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);
        });

如果数据不是一个数组，它就不起作用。

我想应该是，

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

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

【讨论】：

谢谢我改变了你的建议，但现在它说：$scope.customerDetails.splice is not a function
这是因为，$scope.customerDetails 不是一个数组。你能控制 DATA 的帖子并给我回复吗？
我不明白该怎么做？
我的意思是写 console.log(data)。并在浏览器控制台中检查。更新你的qus。用这个值。
在哪里正确呢？在控制台中？对不起，我是新手
