Jaxon 不會在響應中返回任何內容

Question

請問，有人可以幫忙嗎？

我開始使用 jaxon 3，計划從 xajax 遷移。 在一個 php7.3 平台上，我編寫了一個簡單的代碼，只是為了加載 jaxon 並運行一個警報腳本，但它在瀏覽器上沒有返回任何內容。 服務器日志上沒有錯誤，瀏覽器上也沒有信息，甚至在 chrome 調試控制台上也沒有。

這是簡單的代碼：

<?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：我沒有在標簽上使用 jaxon 詞，因為編輯不讓我這樣做

我會告訴你最后刪除回聲，並嘗試編寫一些函數甚至進行測試，這樣你就可以更好地理解 v3。

在這里，檢查此代碼，它可能會對您有所幫助，此代碼已經過測試並且可以工作。

<?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');

$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;
}

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

    );
    $jaxonResponse->setReturnValue($someData);
    $jaxonResponse->getOutput();
    return $jaxonResponse;
