PHP to Javascript通過AJAX/XML變量

首先要說清楚。我想在不使用jQuery的情況下做到這一點，換句話說，是的，我想重新發明輪子以瞭解輪子的工作原理。據我的理解，這可能通過AJAX，但網絡似乎只提供jQuery解決方案的問題。我的目標是使用javascript生成html文檔，但是在頁面已經通過javascript將僅輸出文檔outerHTML的非腳本存根輸出到僅包含指定文本的新.php文件之後。PHP to Javascript通過AJAX/XML變量

的index.php

<!DOCTYPE html> 

<?php 
    include 'devScript.php'; 

    $div = new Div(); 
    $div->setBounds(0, 0, 100, 100); 
?>

devScript.php

<script type="text/javascript"> 

    var srcScript; 
    var devScript; 
    var stubScript; 

    (function() { 

     document.documentElement.appendChild(document.createElement('body')); 

     srcScript = document.head.innerHTML; 



    }()); 


    window.onload = function() { 



     devScript = document.head.innerHTML.toString().replace(srcScript, ''); 
     document.documentElement.removeChild(document.documentElement.lastChild); 

     stubScript = document.documentElement.outerHTML.toString().replace(srcScript, '').replace(devScript, ''); 

     alert("Full Script!"); 
     alert(document.documentElement.outerHTML); 
     alert('Stub Script'); 
     alert(stubScript); 

<?php 
/*

    This DOES NOT WORK!!!!

    function horizontalAlign() { 

     echo '<script>', 
     $this->obj_id . '.horizontalAlign();', 
     '</script>'; 
    } 

} 
?>

注：問題的根源是在index.php中。隨意在Firefox上測試這兩個，因爲警報框有一個滾動條。 :)

OUTPUT： iHateWritingHtmlTags.php只包含「stubScript」作爲其文本而不是實際的javascript變量stubScript？！？！

@SLaks你碰巧有跨瀏覽器的代碼實現嗎？我想通過錯誤步驟跳過試用版。 :) – StoneAgeCoder

XMLHttpRequest是跨瀏覽器，如果你想要處理所有瀏覽器的東西（包括舊版本的IE等），可以使用jQuery或其他一些爲你處理這種抽象的框架。 – Busches

讓「變量」是的Javascript變量名稱現在

<form action="." method="get"> 

<input type='hidden' name='Javascript_Variable' value='<script>document.write(variable);</script>'> 

</form>

，在PHP中：

<?php 

$phpVariable = $_GET['Javascript_Variable']; 

?>

這是很好的存儲一個PHP變量到JavaScript，但我需要反之亦然。 – StoneAgeCoder

然後你可以通過創建一個隱藏的輸入類型來保留這個過程，該隱藏的輸入類型的值是javascript變量的值，然後通過獲取$ _GET ['隱藏輸入的名稱]的值來獲取PHP變量] – user2938543

你請介意以您建議的方式編輯您的答案。 – StoneAgeCoder
