VC中SendMessage和PostMessage的区别

主要介绍了VC中SendMessage和PostMessage的区别,较为全面的分析了SendMessage和PostMessage运行原理及用法上的不同之处,非常具有实用价值,需要的朋友可以参考下

// 获取页面元素 const chatbot = document.getElementById('chatbot'); const chatHeader = document.getElementById('chat-header'); const chatClose = document.getElementById('chat-close'); const chatMessages = document.getElementById('chat-messages'); const chatInput = document.getElementById('chat-input'); const chatInputBox = document.querySelector('#chat-input input'); const chatSend = document.getElementById('chat-send'); // 客服自动回复 function chatbotReply(message) { const reply = '这是客服自动回复的消息：' + message; const received = document.createElement('div'); received.className = 'message received'; received.textContent = reply; chatMessages.appendChild(received); chatMessages.scrollTop = chatMessages.scrollHeight; } // 用户发送消息 function sendMessage() { const message = chatInputBox.value; if (!message) { return; } const sent = document.createElement('div'); sent.className = 'message sent'; sent.textContent = message; chatMessages.appendChild(sent); chatMessages.scrollTop = chatMessages.scrollHeight; chatInputBox.value = ''; chatbotReply(message); } // 关闭客服窗口 chatClose.addEventListener('click', function() { chatbot.style.display = 'none'; }); // 发送消息 chatSend.addEventListener('click', function() { sendMessage(); }); chatInputBox.addEventListener('keydown', function(event) { if (event.key === 'Enter') { sendMessage(); } }); // 显示客服窗口 window.addEventListener('load', function() { chatbot.style.display = 'block'; });这个代码要加到1哪里

const chatInput = document.getElementById('chat-input'); const chatInputBox = document.querySelector('#chat-input input'); const chatSend = document.getElementById('chat-send'); // 客服自动回复 ...

把下面代码完善一下：接下来，在当前目录下创建一个名为templates的目录，并在该目录下创建一个名为index.html的文件，编写如下代码：复制 <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Chat with OpenAI</title> <script> function sendMessage() { const message = document.getElementById("message").value; const conversationId = document.getElementById("conversationId").value; const xhr = new XMLHttpRequest(); xhr.open("POST", "/ask"); xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xhr.onload = function() { if (xhr.status === 200) { const response = xhr.responseText; const responseContainer = document.getElementById("response"); responseContainer.innerHTML = response; } }; xhr.send(message=${encodeURIComponent(message)}&conversationId=${encodeURIComponent(conversationId)}); } </script> </head> <body> Chat with OpenAI <input type

uiHandler.sendMessage(message);

这个代码片段看起来像是在 Android 应用程序中使用 UI 线程处理程序（UIHandler）发送消息（message）的部分。在 Android 应用程序中，所有的 UI 操作都必须在 UI 线程中完成，否则会抛出异常。因此，当您需要在非 ...
