這是代碼的主體。基本上我正在嘗試爲聊天服務器編寫客戶端頁面。假設服務器交互是正確的，頁面將永遠不能接收從服務器發回的消息，因爲每當我點擊輸入時頁面刷新。代碼應該向服務器發送消息，然後服務器將消息發送給所有連接的客戶端，客戶端將消息追加到列表的末尾。我正在嘗試爲網頁創建一個聊天功能，並且當我按下回車鍵時它會不斷重新加載。誰能告訴我爲什麼會發生這種情況？

對這個重載的主要罪魁禍首是進入聊天功能：
$("#enterChat").click(function() {
var messageValue = $("#chatMessage").val();
console.log("Entered by User: %s", messageValue);
sendChat(messageValue);
});
如果任何人都可以點我朝着爲什麼頁面重新加載，我可以朝看是否來自服務器的消息是實際工作正確傳遞。最重要的是，我真的很感激它。
