我担心您需要提供更多详细信息以获得准确的回复，显然您要求

“使用javascript”
从html表中选择所有数据

会让我相信你想把实际的html保存到mySQL吗？

您的问题可能需要针对您的表格进行特定编码，或者针对更一般的方法......这取决于您的确切需求。

作为一般概念，你可以浏览每个TR并为每个TR做一个ajax请求......

$("#yourtableselector tr").each(function() {
var postData = {};
//use $(this).find or similar to get the data you need for each td and add it to the postData variable
$.ajax({ post the data here to a php file of your chosing, that adds the "data" in the database });
});

如何在html表中选择所有数据并使用ajax将其发送到我的数据库
