这是我之前post的延续。 我使用AngularJS的路由来加载不同的html文件。 对于学生显示，使用$ http.get从SQL数据库中检索数据。
我想检查我的ajax.php是否真的有效。
从浏览器开始运行时localhost/ajax.php
然后可以看到信息
MySQL host info:
[{"0":"1","id":"1","1":"Mark","Name":"Mark","2":"Male","Gender":"Male","3":"London","City":"London"},
{"0":"2","id":"2","1":"John","Name":"John","2":"Male","Gender":"Male","3":"Chenni","City":"Chenni"},
{"0":"3","id":"3","1":"Hint","Name":"Hint","2":"Male","Gender":"Male","3":"Singapore","City":"Singapore"},
{"0":"4","id":"4","1":"Sara","Name":"Sara","2":"Female","Gender":"Female","3":"Sydney","City":"Sydney"},
{"0":"5","id":"5","1":"Tom","Name":"Tom","2":"Male","Gender":"Male","3":"New York","City":"New York"},
{"0":"6","id":"6","1":"Pam","Name":"Pam","2":"Male","Gender":"Male","3":"Los Angeles","City":"Los Angeles"},
{"0":"7","id":"7","1":"Catherine","Name":"Catherine","2":"Female","Gender":"Female","3":"Chicago","City":"Chicago"},
{"0":"8","id":"8","1":"Mary","Name":"Mary","2":"Femal","Gender":"Femal","3":"Houston","City":"Houston"},
{"0":"9","id":"9","1":"Mike","Name":"Mike","2":"Male","Gender":"Male","3":"Phoenix","City":"Phoenix"},
{"0":"10","id":"10","1":"Rosie","Name":"Rosie","2":"Female","Gender":"Female","3":"Manchestor","City":"Manchestor"},
{"0":"11","id":"11","1":"Lim","Name":"Lim","2":"Male","Gender":"Male","3":"Singapore","City":"Singapore"},
{"0":"12","id":"12","1":"Tony","Name":"Tony","2":"Male","Gender":"Male","3":"Hong Kong","City":"Hong Kong"},
{"0":"13","id":"13","1":"Royce","Name":"Royce","2":"Male","Gender":"Male","3":"London","City":"London"},
{"0":"14","id":"14","1":"Hitler","Name":"Hitler","2":"Male","Gender":"Male","3":"Germany","City":"Germany"},
{"0":"15","id":"15","1":"Tommy","Name":"Tommy","2":"Male","Gender":"Male","3":"New Jersy","City":"New Jersy"}]
看起来很正确。 我的数据库有以下数据。
id Name Gender City
1 Mark Male London
2 John Male Chenni
3 Hint Male Singapore
4 Sara Female Sydney
5 Tom Male New York
6 Pam Male Los Angeles
7 Catherine Female Chicago
8 Mary Femal Houston
9 Mike Male Phoenix
10 Rosie Female Manchestor
11 Lim Male Singapore
12 Tony Male Hong Kong
13 Royce Male London
14 Hitler Male Germany
15 Tommy Male New Jersy
我的疑问是
如何以其他更好的替代方式调试我的ajax.php？我使用Netbeans IDE。 我在学生链接显示数据时遇到问题。 名称不会显示。如果ajax.php没有问题，哪里可能有问题？
由于
编辑： 我将代码更改为
connect.php
<?php
// db credentials
define('DB_HOST', 'localhost');
define('DB_USER','root');
define('DB_PASS','nyan');
define('DB_NAME','Students');
// Connect with the database.
function connect()
{
$connect = mysqli_connect(DB_HOST ,DB_USER ,DB_PASS ,DB_NAME);
if (mysqli_connect_errno($connect))
{
die("Failed to connect:" . mysqli_connect_error());
}
mysqli_set_charset($connect, "utf8");
return $connect;
}
?>
Ajax.php
<?php
require 'connect.php';
$connect = connect();
// Get the data
$students = array();
$sql = "SELECT id, Name, Gender, City FROM tblStudents";
if($result = mysqli_query($connect,$sql))
{
$count = mysqli_num_rows($result);
$cr = 0;
while($row = mysqli_fetch_assoc($result))
{
$students[$cr]['id'] = $row['id'];
$students[$cr]['Name'] = $row['Name'];
$students[$cr]['Gender'] = $row['Gender'];
$students[$cr]['City'] = $row['City'];
$cr++;
}
}
$json = json_encode($students);
echo $json;
exit;
?>
的script.js
var app = angular.module("Demo", ["ngRoute"])
.config(function($routeProvider){
$routeProvider
.when("/home", {
templateUrl:"Templates/home.html",
controller:"homeController"
})
.when("/courses", {
templateUrl:"Templates/courses.html",
controller:"coursesController"
})
.when("/students", {
templateUrl:"Templates/students.html",
controller:"studentsController"
})
})
.controller("homeController", function($scope){
$scope.message = "Home Page";
})
.controller("coursesController", function($scope){
$scope.courses = ["C#", "VB.NET", "SQL Server", "ASP.NET"];
})
.controller("studentsController", function ($scope, $http) {
$http.get("ajax.php") .then(function(response) {
$scope.students = response;
});
});
看起来没问题，但是当我按下F12时Chrome仍然出错。
GET http://localhost:8383/favicon.ico net::ERR_EMPTY_RESPONSE
我测试了Ajax.php和connect.php到/ var / www / html文件夹并运行localhost / Ajax.php 返回的数据是正确的，如下所示。
[{"id":"1","Name":"Mark","Gender":"Male","City":"London"},{"id":"2","Name":"John","Gender":"Male","City":"Chenni"},{"id":"3","Name":"Hint","Gender":"Male","City":"Singapore"},{"id":"4","Name":"Sara","Gender":"Female","City":"Sydney"},{"id":"5","Name":"Tom","Gender":"Male","City":"New York"},{"id":"6","Name":"Pam","Gender":"Male","City":"Los Angeles"},{"id":"7","Name":"Catherine","Gender":"Female","City":"Chicago"},{"id":"8","Name":"Mary","Gender":"Femal","City":"Houston"},{"id":"9","Name":"Mike","Gender":"Male","City":"Phoenix"},{"id":"10","Name":"Rosie","Gender":"Female","City":"Manchestor"},{"id":"11","Name":"Lim","Gender":"Male","City":"Singapore"},{"id":"12","Name":"Tony","Gender":"Male","City":"Hong Kong"},{"id":"13","Name":"Royce","Gender":"Male","City":"London"},{"id":"14","Name":"Hitler","Gender":"Male","City":"Germany"},{"id":"15","Name":"Tommy","Gender":"Male","City":"New Jersy"}]
所以Ajax.php和connect.php正在运行。只是AngularJs脚本无法正确检索。我的Script.js有什么问题？
