javascript function can't find the element

I need to call some file uploader JavaScript from code behind. The JavaScript is basically customizing the style of the file uploader control. However, the JavaScript function can't find the element. I get this from the inspector:
*o = {element: null,
action: "/Web/UploadHandler.axd?UploadID=55f3930c-6aa9-4201…ccfdfae6c6&ObjectID=145649&RelationshipTypeID=223",
sizeLimit: 209715
when it should look like this:
o = {element: div#uploadContent, action: "/Web/UploadHandler.axd?UploadID=c1829b40-7869-4f19…411e7a542c&ObjectID=151808&RelationshipTypeID=223", sizeLimit: 20971520, acceptTypes: "image/*", onSubmit: ƒ, …}
qq.extend
This is the code:
div = new HtmlGenericControl("div") { ID = ("dlWrapper") };
Literal litScript = new Literal();
litScript.Mode = LiteralMode.PassThrough;
div.Controls.Add(litScript);
var imageUploader = (ImageUpload)CreateImageUploader(ActiveObject, p, litScript);
div.Controls.Add(imageUploader);
controls.Add(div);
private static Control CreateImageUploader(ObjectInstance objectInstance, PropertyType propertyType, Literal litScript)
{

PropertyInstanceValue piv = objectInstance.GetPropertyInstanceValue(propertyType.Id);
return imageUpload;
}
public class ImageUpload : FileUpload

}

protected override void OnLoad(EventArgs e)

sb.Append("<div id=\"uploadContent\"></div>");
litScript.Text = sb.ToString();
sb.Remove(0, sb.Length);
sb.Append("<script type=\"text/javascript\">");
int maxBytes = ProcessUnity.Common.Utility.GetMaxRequestLength() * 1024;
sb.Append("var uploader = new qq.FileUploader({ element: document.getElementById('uploadContent'), action: '" + Context.Request.ApplicationPath + "/UploadHandler.axd?UploadID=" + UploadID + "&ObjectID=" + ActiveObject.Id + "&RelationshipTypeID=" + EDM.Common.Definitions.RelationshipTypeId.IMAGE_FILE + "', sizeLimit: " + maxBytes + ", acceptTypes:'" + accept + "', onSubmit: uploadStart, onComplete: uploadComplete, onError: uploadError, multiple: false });");
sb.Append("</script>");
if (scriptManager != null)
{
ScriptManager.RegisterClientScriptBlock(this, typeof(ImageUpload), Guid.NewGuid().ToString(), sb.ToString(), false);
}
else
{
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), Guid.NewGuid().ToString(), sb.ToString());
}
base.OnLoad(e);
}
private object GetScriptManager()
{
foreach (DictionaryEntry entry in Page.Items)
{
if (entry.Key.ToString().IndexOf("System.Web.UI.ScriptManager") >= 0)
{
return entry.Value;
}
}
return null;
}
}

It looks like you're expecting litScript here:
Literal litScript = new Literal();
litScript.Mode = LiteralMode.PassThrough;
div.Controls.Add(litScript);
To be modified by the OnLoad event:
protected override void OnLoad(EventArgs e)
{
Literal litScript = new Literal();
// ...
StringBuilder sb = new StringBuilder();
sb.Append("<div id=\"uploadContent\"></div>");
litScript.Text = sb.ToString();
// ...
base.OnLoad(e);
}
But your OnLoad is constructing its own local Literal. Just because it has the same litScript name as the outer Literal doesn't mean that the two are related. In short, nothing is writing that div to the page.

Java Server, html client, unable to send messages to server

i got a little problem with my project. I have a Server written in Java and some clients written in html/js. Connecting works somehow, but as soon as i want to send a message from the client to the server it returns an error: "Uncaught InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state"
Hopefully some of you awesome guys can look over my code and help me :)
Server Code:
Server.java
public class Server {
static ArrayList<Clients> clientsArrayList = new ArrayList<>();
private static int clientCount = 1;
private static int port;
private static ServerSocket ss;
private Socket socket;
private Clients clienthandler;
static boolean isRunning = true;
public Server(int port) throws IOException {
this.port = port;
setSs(new ServerSocket(port));
}
public void run() throws IOException {
while (isRunning) {
log("Listening on " + port + "...");
socket = getSs().accept();
log("Receiving client... " + socket);
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream());
String s;
while ((s = in.readLine()) != null) {
log(s);
if (s.isEmpty()) {
break;
}
}
log("Creating a new handler for this client...");
clienthandler = new Clients(socket, "Client " + clientCount, in, out);
Thread t = new Thread(clienthandler);
clientsArrayList.add(clienthandler);
log("Added to client list");
t.start();
clientCount++;
GUI.texttoclientlog();
}
}
public static ServerSocket getSs() {
return ss;
}
public static void setSs(ServerSocket ss) {
Server.ss = ss;
}
public void log(String logtext) {
System.out.println(logtext);
GUI.texttolog(logtext);
}
}
Clients.java
public class Clients implements Runnable {
private String name;
final BufferedReader in;
final PrintWriter out;
Socket socket;
boolean isloggedin;
public Clients(Socket socket, String name, BufferedReader in, PrintWriter out) {
this.out = out;
this.in = in;
this.name = name;
this.socket = socket;
this.isloggedin = true;
}
#Override
public void run() {
String received;
while (true) {
try {
// receive the string
received = in.readLine();
System.out.println(received);
GUI.messagehandler(this.getName() + ": " + received);
if (received.equals("logout")) {
this.isloggedin = false;
this.socket.close();
break;
}
this.in.close();
this.out.close();
this.out.flush();
this.out.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
}
public String getName() {
return name;
}
}
And the JS client code:
<script>
var connection;
connection = new WebSocket("ws://localhost:6788/");
console.log("connection established");
connection.onmessage = function (e) { console.log(e.data); };
connection.onopen = () => conn.send("Connection established");
connection.onerror = function (error) {
console.log("WebSocket Error" + error);
};
function Send() {
if (connection.readyState === 1) {
connection.send("test");
}
console.log("error sending");
}
</script>

The WebSocket session is established via a handshake.
Post the handshake is complete and the connection is upgraded, the server and client can send messages. Here is a sample WebSocket server in Java.
Update the clients run method to
public void run() {
int len = 0;
byte[] b = new byte[80];
while(true){
try {
len = in.read(b);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(len!=-1){
byte rLength = 0;
int rMaskIndex = 2;
int rDataStart = 0;
//b[0] is always text in my case so no need to check;
byte data = b[1];
byte op = (byte) 127;
rLength = (byte) (data & op);
if(rLength==(byte)126) rMaskIndex=4;
if(rLength==(byte)127) rMaskIndex=10;
byte[] masks = new byte[4];
int j=0;
int i=0;
for(i=rMaskIndex;i<(rMaskIndex+4);i++){
masks[j] = b[i];
j++;
}
rDataStart = rMaskIndex + 4;
int messLen = len - rDataStart;
byte[] message = new byte[messLen];
for(i=rDataStart, j=0; i<len; i++, j++){
message[j] = (byte) (b[i] ^ masks[j % 4]);
}
System.out.println(new String(message));
b = new byte[80];
}
}
}
based on this SO answer
In my opinion you can leverage the Spring WebSocket support, rather than writing your own. I had created one which also uses ProtoBuf or you can look at the Spring WebSocket getting started guide here

Thats the updated code. it receives the bytes from the html clients. but i have no clue how to decode them :)

Mustache/handlebars templating: figure out context data structure from template html

In mustache/handlerbars or any templating system in js,
are there any tools to gather all the variables that a template refers to?
for example, given input
templateHTML:
<div class="{{divclass}}">
{#item}}
<h1>{{title}}</h1>
<span>{{text}}</span>
{{/item}}
</div>
would return
{
divclass: "",
item: {
title: "",
text: ""
}
}
when used like MyTemplateTool.getTemplateData(templateHTML)
I tried googling around and checking out handlebars docs but could not find anything suitable

I believe it's just .. See the related docs on paths. Example:
{{#srcs}}
<script src="{{.}}"></script>
{{/srcs}}

I had the same in mind and I thought it was worth while writing something so here you go:

Give the template file path at the command line - you need java 7 or higher to open the file, or you can just rewrite the readFile - method. You can produce a json or java 'schema' by changing the format at the top of the class. The 'schema' gets written to stdout, you can copy it from there and paste it into where you need it. Hope this helps. Ah! This doesn't support partials or set delimiters, but if you get round to writing support ping it to me as I might want it :)
