當我想要發送數據時即時獲得一個箴言o在頁面加載時從集線器啓動一個子集。患病把這個樣本代碼,因爲是短SignalR發送數據頁面加載
這是我chat.vb
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web
Imports SignalR.Hubs
Public Class Chat
Inherits Hub
Public Sub Send(message As String)
' Call the addMessage method on all clients
Clients.addMessage(message)
End Sub
End Class
,這是我的Default.aspx
<script src="Scripts/jquery-1.6.4.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.signalR-0.5.3.js" type="text/javascript"></script>
<script src="signalr/hubs" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(function() {
// Proxy created on the fly
var chat = $.connection.chat;
// Declare a function on the chat hub so the server can invoke it
chat.addMessage = function (message) {
$('#messages').append('<li>' + message + '</li>');
};
$("#broadcast").click(function() {
// Call the chat method on the server
chat.send($('#msg').val());
});
// Start the connection
$.connection.hub.start();
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div style="position: absolute; left: 0; top: 0; height: 100%; width: 100%">
<input type="text" id="msg" />
<input type="button" id="broadcast" value="broadcast" />
<ul id="messages">
</ul>
</div>
</form>
</body>
我不想按下按鈕,我想他DOIT全部由自己當加載頁面
當我把它像這樣
<script language="javascript" type="text/javascript">
$(document).ready(function() {
// Proxy created on the fly
var chat = $.connection.chat;
// Declare a function on the chat hub so the server can invoke it
chat.addMessage = function (message) {
$('#messages').append('<li>' + message + '</li>');
};
chat.send('Hello World');
// Start the connection
$.connection.hub.start();
});
</script>
我有一個連接問題 我得到這個錯誤「SignalR:連接必須在數據可以發送之前啓動。之前。發送調用。開始()()「;
我做了IT,我必須刪除該功能並且不用它就像這樣 ,但我必須從任何函數之外調用它,因爲它們內部不起作用。謝謝 –
