Question

我正在学习angularJs，我想用php和angularJs创建基本的crud应用程序我坚持删除部分，请帮帮我这是我的代码：
HTML

<ul>
    <li ng-repeat="data in data">
        {{data.ID}}
        {{data.subject}}
        {{data.body}}
        <a ng-click="delete(data.id)" href="">Delete</a>
    </li>
</ul>

JS

$scope.delete = function(){
    var id = $scope.data.id;
        that = this;
    $http.get("delete.php?id=" + id)
        .success(function(data){
            $scope.data.splice(that.$index, 1);
        })
}

Php

 include('config.php');
    mysql_select_db('ngdb');
    $id = $_GET ['id'];
    $sql = "SELECT * FROM story";
    $records = mysql_query($sql);

    if(isset($_GET ['id'])){
        $id = $_GET ['id'];
        $delete = "DELETE FROM story WHERE id= '$id'";
        $res = mysql_query($delete) or die ("FAILED" .mysql_error());

    }

我哪里错了？

Answer 1

您需要将$index传递给delete方法并从data对象

中删除该项目

HTML

<ul>
    <li ng-repeat="row in data">
        {{row.ID}}
        {{row.subject}}
        {{row.body}}
        <a ng-click="delete(row.ID, $index)">Delete</a>
    </li>
</ul>

JS

$scope.delete = function(deletingId, index){

    $http.get("delete.php?id=" + deletingId)
        .success(function(data){
            $scope.data.splice(index, 1);
        })
}

也不要做

为ng-repeat键使用不同的名称（现在我更改为row而不是data）
不要清空属性href =＆＃34;＆＃34;因为当你点击这整个页面时可能会刷新（现在我删除了这个）
不要在PHP中使用弃用的语法。使用PDO代替mysql_*

其他简单的解决方案：

$scope.deleteUser = function (user) {
    $http.delete("php/delete.php", {params: {id: user}}).success(function (data, status){
    });
};

从此链接：Angular - $http.delete returns success but doesn't works

php代码也在链接上。

var uid = 1;
var app = angular.module('myApp', []);
   app.controller('customersCtrl', function($scope, $http) {

$scope.addNewFriend = function(add){

};


$scope.delete = function(deletingId, index){

                    $scope.names1 = angular.copy($scope.names[index]);
