AJAX调用PHP文件：返回值为空

本文介绍了AJAX调用PHP文件：返回值为空的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个简单的ajax调用：

I have a simple ajax call:

function init() { $.ajax({ url: "./myFolder/user.php", data: { action: "init" }, type: "post", success: function (output) { console.log("Success"); console.log("Output: " + output); } }); }

PHP init 方法被调用，只需返回一些json数据：

The PHP init method gets called and simply should return some json data:

function init() { $arr = array( array( "region" => "valore", "price" => "valore2" ), array( "region" => "valore", "price" => "valore2" ), array( "region" => "valore", "price" => "valore2" ) ); return json_encode($arr); }

但我的控制台说：

Success Output:

所以输出变量为空。我的json数据在哪里？

So the output variable is empty. Where is my json data?

推荐答案

在 user.php 页面上你需要这样做： -

On user.php page you need to do :-

function init() { $arr = array( array( "region" => "valore", "price" => "valore2" ), array( "region" => "valore", "price" => "valore2" ), array( "region" => "valore", "price" => "valore2" ) ); echo json_encode($arr); }
