提交表单传递的Javascript变量到PHP

这个问题从我的previous问题counting使用PHP 在HTML表中的行。 因为我没有工作的解决方案，我想尝试一种新的方式，但不知道如何实现它。 我分配唯一的ID添加的每个动态记录使用Javascript。因此，在JavaScript中计数变量存储的行present以HTML表格的数量。当我提交表单，它是由 savedata.php 处理。是否可以自动通过JavaScript变量计数 savedata.php 每个表单提交的时间。

This question follows from my previous question counting the rows in html table using php. Since I got no working solution, I want to try a new way but dont know how to implement it. I assign unique ID to each dynamic row added using Javascript. So the count variable in Javascript stores the number of rows present in HTML table. When i submit the form, it is processed by savedata.php. Is it possible to automatically pass the Javascript variable count to savedata.php each time the form is submitted.

下面是用于创建唯一ID的动态创建行元素的短版我的JavaScript文件。

Following is a short version of my Javascript file that is used to create unique IDs for elements of dynamically created rows.

var count=2;

function addRow()
{


var table=document.getElementById("studenttable");
var row=table.insertRow(-1);
var cell15=row.insertCell(14);

var ipt8 = document.createElement('input');
    ipt8.setAttribute("type", "hidden");
    ipt8.id = "text" + count; 
    ipt8.name = "htmlrow[]";      
    ipt8.value = count;        
    cell15.appendChild(ipt8);
count++;
}

新行被添加每次计数的增量，所以才将它传递到PHP文件将允许获取HTML表中的行数。我想每一个表单提交的时候自动进行。

Each time a new row is added, count increments, so just passing it to the PHP file will allow to get the number of rows in HTML table. I want to do it automatically each time the form is submitted.
