Question

我有一个用于应用程序的消息传递应用程序模板，但是我不知道如何结合JavaScript使该模板正常工作。我至少要发送消息。我该怎么办？

我当前拥有的代码：

我只希望至少能够发送消息。但是我知道我需要像Python或Java这样的东西才能做到这一点。

该项目看起来很棒！是的，您需要一些JavaScript来处理来自

的用户输入

<input type="text" placeholder="Type Something Here..." name="message-to-send" id="message-to-send">

我建议查看类似 document.getElementById（“要发送的消息”）之类的内容，以开始处理输入。祝你好运！
