I am new to handlebars.js and I am trying to display a JSON response with this API https://yts.am/api/v2/list_movies.json
I try to use static and basic JSON data, it is working but when I try to load huge amount I get error

Here's a simple pug file
p Hello
The backend is ordinary node, express, passport, sql so something like
app.get('/example', (request, response) => {
response.render('example.pug');
})
I want the web page to
Connect to a websocket server
Any text that arrives, simply display that where the 'Hello' is
How to do this?
(So, TBC the server looks something like this ... I can easily do that end of it.)
function sendInfoToAnyBrowserConnected() {
connections.forEach(function tell(c) {
if (c.readyState == WebSocket.OPEN) {
c.send("this text gets displayed")
What should I put in my pug file?
I've had to figure it out myself - damn you, SO! Essentially this
<a id="log" size=10></a>
with this
var el = document.getElementById("log");
and this
el.innerHTML = el.innerHTML + "<br>" + e.data;
and that's it.
So in total basically
<html>
<head>
<script type="text/javascript">
function VanillaData() {
var ws = new WebSocket("ws://ws.yours.com:2345");
ws.onopen = function() { ws.send("from www ,v1"); };
ws.onmessage = function(e) {
el.innerHTML = el.innerHTML + "<br>" + e.data;
};
ws.onclose = function() { console.log("ws closed..."); };
}
</script>
</head>
<body>
Your live stuff:
<br>
<a id="log" size=10></a>
<script type="text/javascript">
var el = document.getElementById("log");
VanillaData()
</script>
</body >
</html >
I'm not knowledgeable about pug, so cannot comment on how the .pug file should look.
Using an online html-pug convertor, this does work:
head
script(type='text/javascript').
function VanillaData() {
var ws = new WebSocket("ws://you.com:2345");
ws.onopen = function() { ws.send("from www"); };
ws.onmessage = function(e) {
el.innerHTML = e.data + "<br>" + el.innerHTML;
};
ws.onclose = function() { console.log("ws closed ..."); };
}
| Live stuff:
br
pre#log(size='10').
script(type='text/javascript').
var el = document.getElementById("log");
VanillaData()
Seems to work great.
I have developed an application, and in this application I want to import file Excel to multiple table in my DB, and since i am a beginner in angularJS and .NET, I work with .net web api and angularjs, and I develop a function, it works when I import the data into a singe table, but the problem how to import the data into 3 table in DB !!! . and the 3 tables are linked to each other (in my exemple code there 2 table Candidature and Candidat). My question is: how to import Excel file to multiple table in DB and thank's. ( i work with asp.net web API and angularJS )

//Parse Excel Data
$scope.ParseExcelDataAndSave = function () {
var file = $scope.SelectedFileForUpload;

var reader = new FileReader();
reader.onload = function (e) {
var data = e.target.result;
//XLSX from js-xlsx library , which I will add in page view page

In your web api, you are expecting two arrays for Candidatures and candidat.
But from your controller you are passing only one array of data excelData.
So when it comes to api it doesn't execute this code,
foreach (var data in candidat)
{
db.Candidat.Add(data);
}
Because candidat is either null or undefined. So it can't go through the loop which the below code is never executed.
db.Candidat.Add(data);
I'm trying to implement a websocket-server with Progress OpenEdge. I still didn't get it working.
I've successfully created a socket-server with the example i-sktsv1.p from here.
When I run my html-page, which looks like:
<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8" />
<title>WebSocket Client</title>
<script language="javascript" type="text/javascript">
var wsUri = "ws://localhost:3333/";
var output;
function init() {
output = document.getElementById("output");
testWebSocket();
}
function testWebSocket() {
websocket = new WebSocket(wsUri);
websocket.onopen = function(evt) { onOpen(evt) };
// websocket.onclose = function(evt) { onClose(evt) };
websocket.onmessage = function(evt) { onMessage(evt) };
websocket.onerror = function(evt) { onError(evt) };
}
function onOpen(evt) {
writeToScreen("CONNECTED");
doSend("WebSocket rocks");
}
function onClose(evt) {
writeToScreen("DISCONNECTED");
}
function onMessage(evt) {
writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data+'</span>');
websocket.close();
}
function onError(evt) {
writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
}
function doSend(message) {
writeToScreen("SENT: " + message);
websocket.send(message);
}
function writeToScreen(message) {
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}
window.addEventListener("load", init, false);
</script>
<body>
<h2>WebSocket Test</h2>
<div id="output"></div>
</body>
</html>
I getting a error that the websocket connection could not be established.
The problem is (I think) that Progress offers a socket, not a websocket. Do you know how to get this working?
I would not like to call asp.net server side code with jquery $.ajax .
So I have written a pure javascript ajax file .But when I call webmethod,this do not work.
Can anyony help me out how correct this? THANK you very much .
ajax.js:
var ajax = {
_params: null,
_callback: null,
_xhr: null,
_createXHR: function () {
if (window.ActiveXObject) {

}
else if (window.XMLHttpRequest) {
_xhr = new XMLHttpRequest(); //FireFox,Chrome et.
}
},
_ajaxcallback: function () {
if (_xhr.readyState == 4) {
if (_xhr.status == 200) {
_callback.call(this, _xhr.responseText)
}
}
},
_changeParams: function () {
var args = arguments[0];
var s = "";
for (var i in args) {
s += "&" + i + "=" + args[i];
}
_params = s;

WebForm1.cs:

}
In your markup you need to have a ScriptManager with EnablePageMethods set to true. Doing this will ensure you can call the methods you have marked up with [WebMethod].
In your JavaScript you can then call your method like this: PageMethods.GetModel("userName", "password", OnSuccessMethod, OnFailureMethod); - you won't need any of the ActiveXObject/XmlHttpRequest stuff if you do it this way, which keeps things much simpler.

I am trying to get nowelium / socket.io-titanium to work i have it working on the device but on website i get the following error in my console

CAn anyone tell me why this might be happening???
I wonder if switching it to localhost would fix that.
I researched into Access-Control-Allow-Origin and traced it to the web browser as the culprit if I remember correctly. I eventually started looking for a way to disable the browser from checking for that. In Chrome this is my shortcut path.
...Chrome\Application\chrome.exe --allow-file-access-from-files --disable-web-security
See if that works. I don't know if it really remedies the issue as much as it just suppresses the problem. If you were calling the web page from the host you were trying to access I don't think you'd have this problem at all. For example, when I attempt to access my web service on mydomain.com using the web page mydomain.com/myprogram.html it doesn't complain about cross domain access.
