Php javascript和MySQL表

好的。我正在为我的系设计一个网络应用程序，讲师可以在其中输入他/她正在学习的课程的结果。我已经使用java脚本表成功地创建了接口；完成后，我希望将表的内容发布到我使用MySQL设计的数据库中

有什么办法吗

下面是javascript代码片段

<script type="text/JavaScript">

function addRowToTable()

// if there's no header row in the table, then iteration = lastRow + 1

var row = tbl.insertRow(lastRow);

// left cell
var cellLeft = row.insertCell(0);
var textNode = document.createTextNode(iteration);
cellLeft.appendChild(textNode);

// right cell
var cellRight = row.insertCell(1);
var el = document.createElement('input');
el.type = 'text';
el.name = 'Student_ID' + iteration;
el.id = 'Student_ID' + iteration;

el.size = 30;

el.onkeypress= keyPressTest;
cellRight.appendChild(el);  

//CA cell

“我已经使用java脚本表成功创建了接口；” 不，您的表是由Javascript生成的HTML表。一点也不一样

---

您可以使用AJAX或表单发布数据。阅读和了解更多信息。

您需要遵循以下几个步骤-

• 在构建表之后，用javascript编写一个方法，该方法接受这个表元素并返回一个JSON对象，该对象将被发回服务器。这里将讨论简单的JS代码

• 您将收到在PHP脚本中发布的数据。用这个。fot将数据存储到mySql表中

这是一种罕见的情况，答案对你没有帮助。基本上，你需要开始阅读网络的工作原理，因为你非常缺乏理解。
