将javascript值传递给php并将其POST（同一文件）

我有一个名为sendform.php的文件，它包含一个POST数据并通过邮件发送的表单。将javascript值传递给php并将其POST（同一文件）

现在我有一个JavaScript函数，可以将4个不同的选择字段的选择选项相乘。

 <script language="javascript"> 
     function Calculate() 
     { 
      var h = document.getElementById('bedrag-bol').value; 
      var l = document.getElementById('aantal-bol').value; 
      var h2 = document.getElementById('bedrag-gamma').value; 
      var l2 = document.getElementById('aantal-gamma').value; 
      var h3 = document.getElementById('bedrag-douglas').value; 
      var l3 = document.getElementById('aantal-douglas').value; 
      var h4 = document.getElementById('bedrag-bartsmit').value; 
      var l4 = document.getElementById('aantal-bartsmit').value; 
      var result = h * l * 10 + h2 *l2 * 10 + h3 * l3 * 10 + h4 * l4 * 10; 
      document.getElementById('totaal').innerHTML = result; 
     } 
    </script>

是否有可能POST POST JavaScript变量？我找到了一些关于它的文章，我知道这是可能的，但我无法弄清楚。

你有没有看到术语AJAX？ [这里是一个相当复杂的例子]（http://stackoverflow.com/questions/10534441/javascript-ajax-request-vs-jquery-ajax），但谷歌_“XMLHttpRequest AJAX教程”_ –

Ajax不需要这样做。你也可以有一个''并更新它的'.value'。如果你想传递任何东西而不是一个字符串看看JSON。 – Christoph

@Christoph：AJAX在这里并不是必需的（没有正确地阅读这个问题），但是我对隐藏的领域不是太大。也许改变变化事件的价值属性可能会更好？ –

感谢人的答复的

这奏效了：

的Javascript：

document.aanvraag.totaal.value = result; //assign value to hidden input element.

的Html

<input type="hidden" name="totaal" id="totaal" value="" />

@Christoph谢谢:)

！ 见表格

<form name="aanvraag" method="post" action="" onsubmit="Calculate()">

在这里写下您所有的HTML和当您提交表格，然后才提交表格计算功能调用，并将其粘贴隐藏总价值包括隐藏字段

<input type="hidden" name="totaal" id="totaal" value="" /> 

<input name="Submitform" value="Verstuur" type="submit" /> 

</form>

字段，然后所有值与您的给定的URL发布。
