<script type="text/javascript" src="ajax.js" charset="utf-8"></script>

【js代码 ajax.js】
var myModule = angular.module("HelloAjax",[]);
myModule.controller("HelloAjax",["$scope","$http",function HelloAjax($scope,$http){
/*
$scope.users=[{'username':"zhangsan","email":"[email protected]"},
{'username':"zhangsan2","email":"[email protected]"},
{'username':"zhangsan3","email":"[email protected]"}];
*/
$scope.get_more = function(){
$http({
method: "POST",
url: "./ajax.php",
data:{'username':$scope.username,
'email':$scope.email
}
}).
success(function(data, status) {
//$scope.status = status;
$scope.users = data;
}).
error(function(data, status) {
//$scope.data = data || "Request failed";
//$scope.status = status;
});
}
}]);
【PHP代码 ajax.php】
<?php
//获取参数
$data = file_get_contents("php://input");
$user = json_decode($data);
//查询数据库
$conn = mysql_connect("localhost","root","");
mysql_select_db("test");
$sql ="select username,email from users ";
$res = mysql_query($sql,$conn);
$users = array();
while($row = mysql_fetch_assoc($res)){
$users[] = $row;
}
//当然这里简化了插入数据库
$users[] = array('username'=>$user->username,
'email'=>$user->email);
//返回数据库
echo json_encode($users);
