我正在尝试使用ajax创建聊天客户端。我有一个数据库设置和使用教程的基本信号器聊天客户端设置。我试图让我的数据库工作,但我似乎无法让它进行沟通。
这是我的聊天客户端CSHTML:
@{
ViewBag.Title = "Chat";
}
<h2>General Chat</h2>
<div id="wrapper">
<div id="upper-wrapper">
<div id="available-rooms-dialog">
<h4>Available Rooms</h4>
<button type="button" id="createroom" value="Create Room"></button>
</div>
<div id="discussion-dialog">
<textarea rows="30" cols="50" id="discussion"></textarea>
</div>
</div>
<div id="message-dialog">
<textarea rows="3" id="message">Type your message</textarea>
<br/>
<input type="button" id="sendmessage" value="Post" />
<input type="hidden" id="displayname" />
<input type="checkbox" id="enter-sends-message"/>
Enter sends message
</div>
</div>
@section scripts {
<!--Script references. -->
<!--The jQuery library is required and is referenced by default in _Layout.cshtml. -->
<!--Reference the SignalR library. -->
<script src="~/Scripts/jquery.signalR-2.0.2.min.js"></script>
<!--Reference the autogenerated SignalR hub script. -->
<script src="~/signalr/hubs"></script>
<!--SignalR script to update the chat page and send messages.-->
<script>
$(function () {
// Reference the auto-generated proxy for the hub.
var chat = $.connection.chatHub;
// Create a function that the hub can call back to display messages.
chat.client.addNewMessageToPage = function (name, message) {
// Add the message to the page.
//TODO: Add Record to Server
$('#discussion').append(htmlEncode(name) + " : " + htmlEncode(message) + "\r\n");
};
// Get the user name and store it to prepend to messages.
$('#displayname').val(prompt('Enter your name:', ''));
// Set initial focus to message input box.
$('#message').focus();
// Start the connection.
$.connection.hub.start().done(function () {
$('#sendmessage').click(function () {
// Call the Send method on the hub.
chat.server.send($('#displayname').val(), $('#message').val());
// Clear text box and reset focus for next comment.
$('#message').val('').focus();
});
});
});
// This optional function html-encodes messages for display in the page.
function htmlEncode(value) {
var encodedValue = $('<div />').text(value).html();
return encodedValue;
}
</script>
}
addmessagetopage函数中有一个TODO语句,我相信我应该添加ajax来将消息添加到服务器。我怎么能这样做呢。我有一个ChatController以及一个消息控制器,我可以使用它来执行该过程。我的消息数据库设置如下:
我可以选择任何其他路线,因为截至目前我很困难。
