将javascript值传递给php并将其发布（相同文件）
[英]passing javascript value to php and POST it (same file)
问题描述
I have a file called sendform.php wich include a form that POST the data and send it by mail. 
我有一个名为sendform.php的文件，其中包含一个可发布数据并通过邮件发送的表单。
Now I have a javascript function that multiply select options of 4 different select fields. 现在，我有一个JavaScript函数，可以将4个不同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>

Is it possible to POST the javascript variable with php? 是否可以用php发布javascript变量？ I found some articles about it and I know it is possible but I cant figure it out. 我找到了一些有关它的文章，我知道这是可能的，但我无法弄清楚。

See Form 见表格
<form name="aanvraag" method="post" action="" onsubmit="Calculate()">
Write your all HTML HERE and include hidden field 在此处编写所有HTML，并包含隐藏字段
<input type="hidden" name="totaal" id="totaal" value="" />
<input name="Submitform" value="Verstuur" type="submit" />
</form>
When you submit this form then before submit the form calculate function will call and it paste total value in hidden field and then all value post with your given URL. 当您提交此表单时，在提交表单之前，将调用表单计算功能，它将总值粘贴到隐藏字段中，然后将所有值发布到给定的URL。
