Class Variable Name: addPointY
"addPointY" Using Function:
setInterval(function () {
var y = Math.round(Math.random() * 100);
series.addPoint(this.addPointY, true, true);
}, 3000);
I have to find a way to use it.
This is a customer requirement and has not been resolved.
Please tell me another way.
The class variable must be used in any of its methods.
But I could not get the class variable.
Do not you have a smart developer who solved the same problem?
#Injectable()

The this inside your callback function for setInterval does not point to the current class instance because when you use function () {} syntax it creates its own binding for this based on how it is called.
To fix this use arrow functions which preserves the context and you can access your class properties inside the callback:
load: () => { // Notice arrow function here
// set up the updating of the chart each second
var series = this.series[0];
setInterval(() => { // Notice arrow function here
var y = Math.round(Math.random() * 100);
series.addPoint(this.addPointY, true, true);
}, 3000);
}
Another way you can solve this is by using the that pattern where you capture your this where it points to your class instance and use it wherever you need to refer to your instance:
dynamicInitOptions(title: string, type: string, yAxisTitle: string, series: Object[]) {
if (!type) { type = "line"; }
let that = this; // Capture `this` here
let obj = new Chart({
chart: {
type: type,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var y = Math.round(Math.random() * 100);
series.addPoint(that.addPointY, true, true); // Use `that` instead of `this here
}, 3000);
}
}
}
// ...
});

Learning Laravel event broadcasting / Echo / Vue and playing around with this tutorial.
I keep getting 403 responses to authentication, and I suspect my lack of understanding on the channels.php routes is the issue. I am using Player model instead of User for Auth which works ok.
Event ChatMessageSend
class ChatMessageSent implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $channel;
public $player;
public $chatMessage;
/**
* Create a new event instance.
* GameChat constructor.
* #param $chatMessage
* #param $player
*/
public function __construct(ChatMessage $chatMessage, Player $player)
{
$this->channel = session()->get('chat.channel');
$this->chatMessage = $chatMessage;
$this->player = $player;
}
/**
* Get the channels the event should broadcast on.
*
* #return Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel($this->channel);
}
}
Listener ChatMessageNotification (default / empty)
class ChatMessageNotification
{
/**
* ChatMessageNotification constructor.
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* #param ChatMessageSent $event
* #return void
*/
public function handle(ChatMessageSent $event)
{
//
}
}
Controller ChatController
class ChatController extends Controller
{
/**
* Send chat message
*
* #param Request $request
* #return \Illuminate\Database\Eloquent\Collection|static[]
*/
public function getMessages(Request $request)
{
return ChatMessage::with('player')
->where('progress_id', '=', session('game.progress.id'))
->orderBy('created_at', 'DESC')
->get();
}
/**
* Send chat message
*
* #param Request $request
* #return array|string
*/
public function sendMessage(Request $request)
{
$player = Auth::user();
$message = $request->input('message');
if ($message) {
$message = ChatMessage::create([
'player_id' => $player->id,
'progress_id' => session()->get('game.progress.id'),
'message' => $request->input('message')
]);
}
broadcast(new ChatMessageSent($player, $message))->toOthers();
return ['type' => 'success'];
}
}
Routes channels.php
Broadcast::channel(session()->get('chat.channel'), function ($player, $message) {
return $player->inRoom();
});
And in my Player class
/**
* A user can be in one chat channel
*/
public function inRoom()
{
if ((Auth::check()) and ($this->games()->where('progress_id', '=', session('game.progress.id'))->get())) {
return true;
}
return false;
}
When a player logs in, I store in session a chat room id which I would like to use as channel.
My vue chat instance is
Vue.component('chat-messages', require('./../generic/chat-messages.vue'));
Vue.component('chat-form', require('./../generic/chat-form.vue'));
const app = new Vue({
el: '#toolbar-chat',
data: {
messages: []
},
created() {
this.fetchMessages();
Echo.private(chat_channel)
.listen('chatmessagesent', (e) => {
this.messages.unshift({
message: e.data.message,
player: e.data.player.nickname
});
});
},
methods: {
fetchMessages() {
axios.get(chat_get_route)
.then(response => {
this.messages = response.data;
});
},
addMessage(message) {
this.messages.unshift(message);
this.$nextTick(() => {
this.$refs.toolbarChat.scrollTop = 0;
});
axios.post(chat_send_route, message)
.then(response => {
console.log(response.data);
});
}
}
});
But I keep getting
POST http://my-games.app/broadcasting/auth 403 (Forbidden)
Pusher : Couldn't get auth info from your webapp : 403
Error 403 /broadcasting/auth with Laravel version > 5.3 & Pusher, you need change your code in resources/assets/js/bootstrap.js with
window.Echo = new Echo({
broadcaster: 'pusher',
key: 'your key',
cluster: 'your cluster',
encrypted: true,
auth: {
headers: {
Authorization: 'Bearer ' + YourTokenLogin
},
},
});
And in app/Providers/BroadcastServiceProvider.php change by
Broadcast::routes()
with
Broadcast::routes(['middleware' => ['auth:api']]);
or
Broadcast::routes(['middleware' => ['jwt.auth']]); //if you use JWT
it worked for me, and hope it help you.
It may be an idea to figure out whether your routes/channels.php file is doing as you expect. Maybe add some logging to see if that route gets called at all, and that your inRoom function is returning what you expect.
In case anyone still needs an answer, this worked for me.
Add to your broadcastServiceProvider.php
Broadcast::routes([
'middleware' => 'auth:api']);
add to your channels.php
Broadcast::channel('chat', function () {
return Auth::check();
});
I am trying to create knockout.js component that is getting data from HTML5 Websocket. Websocket code is in separate script e.g. util.js. I am able to connect and get data from socket, but dont know how correctly to set corresponding property in component`s ViewModel.
Websocket - util.js:
var options = {
server: '127.0.0.1',
port: '12345'
};
var socket, loadedFlag;
var timeout = 2000;
var clearTimer = -1;
var data = {};
function handleErrors(sError, sURL, iLine)
{
return true;
};
function getSocketState()
{
return (socket != null) ? socket.readyState : 0;
}
function onMessage(e)
{
data=$.parseJSON(e.data);
// ???? Is it possible to have here something like
// ???? viewModel.getDataWS1(data);
}
function onError()
{
clearInterval(clearTimer);
socket.onclose = function () {
loadedFlag = false;
};
clearTimer = setInterval("connectWebSocket()", timeout);
}
function onClose()
{
loadedFlag = false;
clearInterval(clearTimer);
clearTimer = setInterval("connectWebSocket()", timeout);
}
function onOpen()
{
clearInterval(clearTimer);
console.log("open" + getSocketState());
}
function connectWebSocket()
{
if ("WebSocket" in window)
{
if (getSocketState() === 1)
{
socket.onopen = onOpen;
clearInterval(clearTimer);
console.log(getSocketState());
}
else
{
try
{
host = "ws://" + options.server + ":" + options.port;
socket = new WebSocket(host);
socket.onopen = onOpen;
socket.onmessage = function (e) {
onMessage(e);
};
socket.onerror = onError;
socket.onclose = onClose;
}
catch (exeption)
{
console.log(exeption);
}
}
}
}
Component (productDisplay.js) - creating so that is can be used on multiple pages:
define([
'jquery',
'app/models/productDisplayModel',
'knockout',
'mapping',
'socket'
],
function ($, model, ko, mapping) {
ko.components.register('product', {
viewModel: {require: 'app/models/productModel'},
template: {require: 'text!app/views/product.html'}
});
});
Product ViewModel (productModel.js) - where I struggle to set viewModel property to data from websocket:
var viewModel = {};
define(['knockout', 'mapping', 'jquery'], function (ko, mapping, $) {
function Product(name, rating) {
this.name = name;
this.userRating = ko.observable(rating || null);
}
function MyViewModel() {
this.products = ko.observableArray(); // Start empty
}
MyViewModel.prototype.getDataWS1 = function () {
//Websocket has not connected and returned data yet, so data object is empty
// ???? Is there anyway I can add something like promise so that the value is set once socket is connected?
this.products(data);
};
// apply binding on page load
$(document).ready(function () {
connectToServer1();
viewModel = new MyViewModel();
ko.applyBindings(viewModel);
viewModel.getDataWS1();
});
});
Thank you for any ideas.
You can update an observable when you get a message in the following manner:
util.js
function onMessage(e) {
var productData = $.parseJSON(e.data);
viewModel.addNewProduct(productData);
}
productModel.js
function Product(name, rating) {
this.name = name;
this.userRating = ko.observable(rating || null);
}
function MyViewModel() {
this.products = ko.observableArray(); // Start empty
}
MyViewModel.prototype.addNewProduct(product) {
var newProduct = new Product(product.name, product.rating);
this.products.push(newProduct);
}
Basically the idea is that when you get a message (in onMessage function), you will parse the data and call a function in your viewmodel to add the message data to the viewmodel properties (observables, observableArrays, etc.)
I used the answer at : YUI 3 -Datatable with Paginator + Query Builder + Sort tried
to for the samples http://jsbin.com/iwijek/10 and http://jsfiddle.net/UwjUt/ which have inline json data. I wanted to parse the remote json file for which I used the .get() as per YUI 3 docs. But bit does not do anything. plz check these examples and help me in parsing the remote json file.
{ var url = "file:///e:/Documents/json-search.txt";
var modelList;
dataSource = new Y.DataSource.Get({ source: url });
// comment
// var modelList = new Y.ModelList();
modelList = new Y.ModelList.Get({
source: url });
modelList.add();
}

}]
I also tried to pass the datasource to the ModelList
YUI.add(
'datatable-filter',
function(Y) {
/**
Adds support for filtering the table data by API methods
#module datatable
#submodule datatable-filter
#since 3.5.0
**/
var YLang = Y.Lang,
isBoolean = YLang.isBoolean,
isString = YLang.isString,
isArray = YLang.isArray,
isObject = YLang.isObject,
toArray = Y.Array,
sub = YLang.sub;
/**
<pre><code>
var table = new Y.DataTable({
columns: [ 'id', 'username', 'name', 'birthdate' ],
data: [ ... ],
filters: true // this will render a filter input box for every column
});
table.render('#table');
</code></pre>
Setting `filters` to `true` will enable UI filtering for all columns. To enable
UI filtering for certain columns only, set `filters` to an array of column keys,
or just add `filters: true` to the respective column configuration objects.
This uses the default setting of `filters: auto` for the DataTable instance.
<pre><code>
var table = new Y.DataTable({
columns: [
'id',
{ key: 'username', renderFilter: true },
{ key: 'name' },
{ key: 'birthdate', renderFilter: true, filter : "=123", filterFn : customFilterFn }
],
data: [ ... ]
// filters: 'auto' is the default
});
To disable UI filtering for all columns, set `filters` to `false`. This still
permits filtering via the API methods.
filter via api:
var filterBy =
{
username : "=student",
name : "%richard",
birthdate : ">01-01-1975"
}
table.set("filterBy",filterBy);
As new records are inserted into the table's `data` ModelList, they will be checked against the filter to determine if they will be rendered
The current filters are stored in the `filterBy` attribute. Assigning this value at instantiation will automatically filter your data.
Filtering is done by a simple value comparison using '=', '!=', '<', '<=', '>', '>=' on the field value.
If you need custom filtering, add a filter function in the column's `filterFn` property. // TODO...
<pre><code>
function applePiesFilter(a) {
return a.get("type") == 'apple' ? true : false;
}
var table = new Y.DataTable({
columns: [ 'id', 'username', { key: name, filterFn: nameFilter }, 'birthdate' ],
data: [ ... ],
filters: [ 'username', 'name', 'birthdate' ]
});
</code></pre>
