Question

我正在尝试使用php文件从mysql数据库加载数据，然后将结果加载到我的angularjs文件中。但是，它不起作用。我使用.get（）函数使用$ http服务尝试了它。

config.php：

<?php
define('HOST','localhost');
define('NAME','test');
define('USER','root');
define('PW','');

$mysqli = new mysqli(HOST,USER,PW,NAME);
if(mysqli_connect_errno())
{
 //echo("Failed to connect, the error message is: ".mysqli_connect_error());
 exit();
}
else
{
 //echo "Connection success";
}
?>

loadDatabase.php：

  <?php
require_once'config.php';

$query = "select * from lebensmittel";
$result = $mysqli->query($query);

if(mysqli_num_rows($result) > 0)
{
    echo " Tupels vorhanden";
    while ($row = $result->fetch_assoc()) 
    {
        $data[] = $row;
    }
}

header('Content-Type: application/json');
echo json_encode($data);
?>

controller.js：

angular.module('starter.controllers', [])
.controller('AppCtrl', function ($scope, $ionicModal, $timeout, $http) {

   $scope.items = [];

   function loadData()
   {
       $http.get("http://localhost/4n/db_zugriff/loadDatabase.php").success(function (data) {
           $scope.items = data;
       }).error(function () {
           console.log("Error: can't load from php");
       });
   }

   loadData();

/*
$scope.items = [
   { id: 1, name: 'milk', date: '01-01-2016', amount: 1000 },
   { id: 2, name: 'cheese', date: '01-01-2016', amount: 250 },

];
   */

});

output.html：

<ion-view view-title="Output">
    <ion-content data-ng-app="starter" ng-controller="AppCtrl">

        <ion-list >
            <ion-item ng-repeat="item in items">
                {{item.name}} {{item.date}}
            </ion-item>
        </ion-list>

    </ion-content>
</ion-view>

我该如何解决这个问题？感谢您的帮助！

您的ng-app错误，应该是

  <ion-content data-ng-app="starter.controllers" ng-controller="AppCtrl">

还有一个像这样声明的函数，并在ng-init中调用它，

$scope.loadData = function()
{
 $http.get("http://localhost/4n/db_zugriff/loadDatabase.php").success(function                                                     (data) {
           $scope.items = data;
       }).error(function () {
           console.log("Error: can't load from php");
       });
    });
}

<强> HTML：

  <ion-view view-title="Output">
        <ion-content data-ng-app="starter.controllers" ng-controller="AppCtrl">
            <ion-list ng-init="loadData()">
                <ion-item ng-repeat="item in items">
                    {{item.name}} {{item.date}}
                </ion-item>
            </ion-list>
        </ion-content>
    </ion-view>

AngularJs，Ionic：$ http.get不起作用
