無法使用 angular.js 和 PHP 在視圖上綁定數據

Question

我需要使用 Angular.js 在頁面上顯示數據。 首先，我使用 PHP 從數據庫中獲取了所有數據。頁面上沒有顯示數據。我在瀏覽器控制台中獲取了以下檢索到的數據。

all data [{"0":"1","id":"1","1":"","name":"","2":"","pass":"","3":"","email":""},{"0":"2","id":"2","1":"subhra","name":"subhra","2":"12345","pass":"12345","3":"subh@gmail.com","email":"subh@gmail.com"},{"0":"3","id":"3","1":"rakesh","name":"rakesh","2":"0901209474","pass":"0901209474","3":"maini","email":"maini"},{"0":"4","id":"4","1":"raj","name":"raj","2":"23457","pass":"23457","3":"rai","email":"rai"},{"0":"5","id":"5","1":"Rahul","name":"Rahul","2":"098765","pass":"098765","3":"shinha","email":"shinha"}]

我在下面解釋我的代碼。

閱讀.js：

var app=angular.module('Read_data',[]);
app.controller('readController',function($scope){
    $.ajax({
        type:'GET',
        url:"php/read.php",
        success: function(data){
            $scope.data=data;
            console.log('all data',$scope.data);
        }
    })
});

閱讀.php：

<?php
//database settings
$connect = mysqli_connect("localhost", "root", "*******", "AngularTest");
$result = mysqli_query($connect, "select * from users");
$data = array();
while ($row = mysqli_fetch_array($result)) {
  $data[] = $row;
}
    print json_encode($data);
?>

索引.html：

<body>

<div id="body">
 <div id="content">
    <table align="center">
    <tr>
    <th colspan="5"><a href="add_data.html">add data here.</a></th>
    </tr>
    <th> Name</th>
    <th> Email</th>
    <th> Password</th>
    <th colspan="2">Operations</th>
    </tr>
        <tr ng-repeat="users in data">
        <td>{{users.name}}</td>
        <td>{{users.email}}</td>
        <td>{{users.pass}}</td>
  <td align="center"><a href="edit_data.php?edt_id={{users.id}}"><img src="images/pencil_small.png" align="EDIT" /></a></td>
        <td align="center"><a href="javascript:delete_id('')"><img src="images/cross-small-icon.png" align="DELETE" /></a></td>
        </tr>
    </table>
    </div>
</div>

</center>
</body>
</html>

請幫我解決這個問題並成功綁定表中的所有數據。

Answer 1

Angular 不知道更新的數據。 如果您沒有將$http用於 AJAX，請使用$scope.$apply 。

var app=angular.module('Read_data',[]);
app.controller('readController',function($scope){
    $.ajax({
        type:'GET',
        url:"php/read.php",
        success: function(data){
            $scope.$apply(function(){
                $scope.data = angular.fromJson(data);
            });
            console.log('all data',$scope.data);
        }
    })
});

或使用$http （推薦）

var app=angular.module('Read_data',[]);
app.controller('readController',function($scope, $http){
    $http.get('php/read.php').
        then(function(data) {
            // this callback will be called asynchronously
            // when the response is available
            $scope.data = data.data;
        }, function(response) {
            // called asynchronously if an error occurs
            // or server returns response with an error status.
        });
});
