通过javascript将Input(box）中的数据添加到sql db

Add data in Input(box) to sql db through javascript

本文关键字：数据 添加 db sql javascript Input box 通过      更新时间：2023-09-26

这是我的代码，我正在使用JavaScript中的C#代码将input（box）"纬度"和"longitude"中的数据写入数据库。

我想要的只是每当按下按钮时插入数据。此代码仅在初始化时插入一次数据。按钮单击时不会产生任何影响。

我没有用javascript编码的经验。任何帮助将不胜感激。

JavaScript 运行客户端，不能将 c# "嵌入"到其中，为此，我将 c# 代码移动到它自己的页面并使用 AJAX 向服务器发送/接收数据并相应地执行 C# 代码
