將javascript值傳遞給php並將其POST（同一文件）

Question

我有一個名爲sendform.php的文件，它包含一個POST數據並通過郵件發送的表單。

現在我有一個JavaScript函數，可以將4個不同的選擇字段的選擇選項相乘。

 <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變量？我找到了一些關於它的文章，我知道這是可能的，但我無法弄清楚。

Answer 1

感謝人的答覆的

這奏效了：

的Javascript：

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

的Html

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

@Christoph謝謝:)

Answer 2

！ 見表格

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

在這裏寫下您所有的HTML和當您提交表格，然後才提交表格計算功能調用，並將其粘貼隱藏 總價值包括隱藏字段

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

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

</form> 

字段，然後所有值與您的給定的URL發佈。
