chat.js

var app = angular.module('MyApp', ['ngDialog']);
app.controller('MainCtrl', function ($scope, ngDialog) {
$scope.openChatBox = function() {
    ngDialog.openConfirm({template: 'chatBox.html',
        scope: $scope //Pass the scope object if you need to access in the template
    }).then(
        function(value) {
            //You need to implement the saveForm() method which should return a promise object
            $scope.closeChat().then(

            );
        },
        function(value) {
            //Cancel or do nothing
        }
    );
};
});

socket.js

angular.module('chatSocket', ['ngWebSocket'])
.factory('socket', function ($websocket) {

    // Open a WebSocket connection
    var ws = $websocket("ws://" + document.location.host + document.location.pathname);
    var msg = [];

    ws.onMessage(function (event) {
        console.log('message: ', event.data);
        var response;

        try {
            response = event.data;
        } catch (e) {
            console.log('error: ', e);
        }

        msg.push({
            name: "Bot",
            msg: response,
        });
    });

    ws.onError(function (event) {
        console.log('connection Error', event);
    });

    ws.onClose(function (event) {
        console.log('connection closed', event);
    });

    ws.onOpen(function () {
        console.log('connection open');
        ws.send('HELLO SERVER');
    });

    return {
        msg: msg,
        status: function () {
            return ws.readyState;
        },

        send: function (message) {
            console.log(message);
            msg.push({
                name: "User",
                msg: message,
            });
            ws.send(message);
        }
    };
 })

.controller('msgController', function ($scope, socket) {
$scope.socket = socket;
$scope.submit = function () {
    socket.send($scope.msgbox);
};  
});

如果我没有使用msgController，则会打开对话框。当我包含它时，会显示错误，并且无法打开对话框。

因为您引用了msgController的{{1}} openConfirm方法，而您没有定义它。

ngDialog

除此之外，您已在ngDialog.openConfirm({ template: 'chatBox.html', controller: 'msgController', scope: $scope //Pass the scope object if you need to access in the template })模块中指定了msgController，并且您正在chatSocket模块中使用它，这就是您收到错误的原因。

您需要将MyApp指定为chatSocket模块的依赖关系，并在MyApp模块上定义msgController，例如打击：

MyApp

错误：ng：areq Bad Argument Argument＆＃39; msgController＆＃39;不是一个功能，未定义
