我需要使用 Angular.js 在页面上显示数据。首先，我使用 PHP 从数据库中获取所有数据。这里页面上没有显示任何数据。我在浏览器控制台中获取以下检索到的数据。
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":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1b686e79735b7c767a727735787476" rel="noreferrer noopener nofollow">[email protected]</a>","email":"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="82f1f7e0eac2e5efe3ebeeace1edef" rel="noreferrer noopener nofollow">[email protected]</a>"},{"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"}]
我在下面解释我的代码。
read.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);
}
})
});
read.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);
?>

请帮我解决这个问题并成功绑定(bind)表中的所有数据。
最佳答案
Angular 不知道更新的数据。如果您不使用$http，请使用$scope.$apply用于 AJAX。
var app=angular.module('Read_data',[]);
app.controller('readController',function($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$http(推荐)
var app=angular.module('Read_data',[]);
app.controller('readController',function($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.
});
});
关于php - 无法使用 angular.js 和 PHP 在 View 上绑定(bind)数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32778801/
