为什么我的javascript控制台说Web套接字已关闭或已处于关闭状态？

Question

我正在为我的公司创建一个聊天应用程序，每当我尝试连接时，我都会遇到 Web Socket已关闭或已处于关闭状态的问题。但情况是，相同的源代码相同的应用程序在我的朋友笔记本电脑上工作正常，即使它在我的办公室笔记本电脑上正常工作，但在我的家用笔记本电脑中它给我这个错误，我不知道发生了什么。

这是我的ChatSocket.js代码

var chatsocket = function() {

var messageReceive = "";

var ws;

var messageSend = function(message) {
    var buildMessage = "<div class='row msg_container base_sent'>"
            + "<div class='col-md-10 col-xs-10'> "
            + "<div class='messages msg_sent'>" + "<p>" + message + "</p>"
            + "<time datetime='2009-11-13T20:00'>Timothy • 51 min</time>"
            + "</div>" + "</div>" + "";
    var imgMessage = "<div  class='col-md-2 col-xs-2 avatar'>"
            + "<img src='http://www.bitrebels.com/wp-content/uploads/2011/02/Original-Facebook-Geek-Profile-Avatar-1.jpg'class='img-responsive ' />"
            + "</div>" + "</div>";
    return buildMessage + imgMessage;
};

var messageReceive = function(message) {
    var imgMessage = "<div class='row msg_container base_receive'>" +
            "<div  class='col-md-2 col-xs-2 avatar'>"
            + "<img src='http://www.bitrebels.com/wp-content/uploads/2011/02/Original-Facebook-Geek-Profile-Avatar-1.jpg'class='img-responsive ' />"
            + "</div>";

    var buildMessage = "<div class='col-md-10 col-xs-10'> "
        + "<div class='messages msg_receive'>" + "<p>" + message + "</p>"
        + "<time datetime='2009-11-13T20:00'>Timothy • 51 min</time>"
        + "</div>" + "</div>" + "</div>";
    return imgMessage + buildMessage;
};

var connect = function() {
    var user = $("#user").val();
    try{
        ws = new WebSocket("ws://localhost:8086/EnterpriceChat/chat/" + user);
    } catch(err) {          
        console.log("error");
    }
    ws.onmessage = function(event) {
        var message = JSON.parse(event.data);
        var idSuffix = getElementIdSuffix(message.from);
        createNewChatBox(message.from);
        var msg_panel_id = getMsgPanelId(idSuffix);         
        $("#"+msg_panel_id).append(messageReceive(message.content));
    };

};

var sendMessage = function(element) {
    var inputElementId = element.attr("data-id");
    var to = element.attr("data-id-email");
    var msg_panel_id = element.attr("data-id-msg-panel");

    //Validating the inputs
    var content = $("#"+inputElementId).val();
    //Reset the input fields
    $("#"+inputElementId).val('');
    if(!content) {
        return;
    }

    var json = JSON.stringify({
        "to" : to,
        "content" : content
    });

    ws.send(json);
    $("#"+msg_panel_id).append(messageSend(content));
};

var eventClick = function() {
    $('.btn-chat-send').unbind('click');        
    $('.chat_input').unbind('keypress');

    $('.btn-chat-send').click(function() {
        console.log();
        sendMessage($(this));
    });
    $('.chat_input').keypress(function(e) {
        if(e.which == 13) {
            $(this).closest('.input-group').find('.btn-chat-send').click();
        }
    });     

};

return {
    initEvent : function() {
        connect();
    }, initAction : function() {
        eventClick();
    }       
}
}();

但我不认为我的代码存在问题，因为它在其他计算机上运行良好。
