Jaxon 不会在响应中返回任何内容答案

【问题描述】：

请问，有人可以帮忙吗？

我开始使用 jaxon 3，计划从 xajax 迁移。在一个 php7.3 平台上，我编写了一个简单的代码，只是为了加载 jaxon 并运行一个警报脚本，但它在浏览器上没有返回任何内容。服务器日志没有错误，浏览器也没有信息，甚至在 chrome 调试控制台上也没有。

下面是简单的代码：

<?php


require_once( 'Jaxon/vendor/autoload.php' );
use Jaxon\Jaxon;
use Jaxon\Response\Response;

$ajax = jaxon();
$ajax->setOption('core.debug.on', false);

$ajax->setOption('core.prefix.function', 'jaxon_');

$ajax->setOption('core.request.uri', 'ajax.php');
$objResponse = new Response();



$objResponse->alert('test');
return $objResponse;
echo 'tests';
?>

PS：我没有在标签上使用 jaxon 词，因为编辑器不让我这样做

我会告诉你删除最后的回声，并尝试编写一些函数甚至用于测试，这样你可以更好地理解v3。

在这里，检查一下这段代码，它可能会对你有所帮助，这段代码已经过测试并且可以工作。

<?php
require_once ($_SERVER['DOCUMENT_ROOT'].'/vendor/autoload.php');

use Jaxon\Jaxon;
use Jaxon\Response\Response;

$jaxon = jaxon();

$jaxon->setOption('js.app.minify', TRUE);
$jaxon->setOption('js.lib.uri', '/vendor/jaxon-php/jaxon-js/dist');

/** using jaxon with just functions then you have to register each function 
 * 
 *  call these functions like this:

 *  
*/
$jaxon->register(Jaxon::USER_FUNCTION, 'demo1'); 
$jaxon->register(Jaxon::USER_FUNCTION, 'demo2'); 
$jaxon->register(Jaxon::CALLABLE_FUNCTION, 'functionThatReturnsUsing_setReturnValue', ['mode' => "'synchronous'"]); 

function demo1(){
    $jaxonResponse = new Response();
    $jaxonResponse->alert('Hello there, be sure to open browser console to see the console.log');
    $jaxonResponse->script("console.log('Hello there')");
    
    return $jaxonResponse;
}

function demo2(){
    $jaxonResponse = new Response();

    // <div id="theDiv"> this will be replaced </div>
    $jaxonResponse->assign("theDiv","innerHTML",'Some content that can even be a template if you implement smarty or similar');
    
    return $jaxonResponse;
}

function functionThatReturnsUsing_setReturnValue(){
    $jaxonResponse = new Response();
    // lets suppose you have a script like this

    //    function demo3(){

        )
    );
    $jaxonResponse->setReturnValue($someData);
    $jaxonResponse->getOutput();
    return $jaxonResponse;
}    
    
if($jaxon->canProcessRequest()){
    $jaxon->processRequest();
