How create a angular module to Unity 3D? - javascript

I wish made an Angular module using Unity WebGL. Indeed nothing has already done on this topic and no module existed today.
However, I am little lost and I need help. It would be good if that module will develop to Angular 2. But I know Angular 1 so far.
Unity 3D export gave that:
<!doctype html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Unity WebGL Player | Test Unity</title>
<style>
/* a style sheet needs to be present for cursor hiding and custom cursors to work. */
</style>
</head>
<body>
<canvas class="emscripten" id="canvas" oncontextmenu="event.preventDefault()" height="600px" width="960px"></canvas>
<script type='text/javascript'>
var Module = {
TOTAL_MEMORY: 268435456,
errorhandler: null, // arguments: err, url, line. This function must return 'true' if the error is handled, otherwise 'false'
compatibilitycheck: null,
dataUrl: "Development/ExportMiniDev.data",
codeUrl: "Development/ExportMiniDev.js",
memUrl: "Development/ExportMiniDev.mem",
};
</script>
</body>
</html>
Could you please provide to me something to start. I already pass a lot of my time on this. If I succeed I will publish that module on Github.

Looks like there are now a couple of libraries (I haven't tested them):

Making live python compiler inside a HTML page using PyScript

I want to build a live Pythonn compiler similar to those at w3schools for Python, for some examples on my blog. I tried different approaches, and would like to hear different oppinions, but as of yesterday I'm trying to implement it using PyScript.
The documentation I found for PyScript doesn't help me a lot, as it seems like I can't understand it, or doing something wrong.
Here's the code that I'm trying to implement:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title>Writing to the page</title>
<link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
<script defer src="https://pyscript.net/latest/pyscript.js"></script>
<textarea id="area1" rows="15">something</textarea>
<button onclick="myFunction()">Click me</button>
<py-script id="demo">
print("Hello, world!")
</py-script>
<py-terminal></py-terminal>
<script>
function myFunction() {
var text1 = document.getElementById('area1').value;
document.getElementById("demo").innerHTML = text1;
}
</script>
</body>
</html>
It just prints the content of the textarea above the terminal, without executing the code and printing the output, inside the terminal, as I imagined.
I'm expecting to make this functinal, and I tried a few things, but unsuccessfully.
I also tried:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title>Writing to the page</title>
<link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
<script defer src="https://pyscript.net/latest/pyscript.js"></script>
<textarea id="area1" rows="15">print("something")</textarea>
<script>
let text1 = document.getElementById('area1').value;
</script>
<py-script>
def print_to_page(x):
exec(x)
</py-script>
<button py-click="print_to_page(text1)" id="print">Run!</button>
</body>
</html>
But I'm not sure how to pass the variable from JS to PyScript.

Something like that may integrate well with your blog. You can hack around on it and hopefully put together what you need combined with that example and the documentation.

Alternative approaches:
JupyterBook and MyST-NB seems to be moving along this route. For example see the Render option the left side there.
I'm not sure all the pieces are together but you can imagine with the JupyterLite/pyodide stuff it soon will be set for blogs.) Quarto may be heading that way, too.

Based on your description and the second example, it looks like you want to have a textarea where the user types in Python code, and run button that executes that entered code when clicked. If I've misunderstood your goal, you can disregard this answer.
The way to bring JavaScript objects/variables into Python is using Pyodide's import js syntax, which treats the JavaScript global namespace like a Python module. Here's a version very similar to your second example, which imports JavaScript's document object and uses that to extract the value of the textarea:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title>Writing to the page</title>
<link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
<script defer src="https://pyscript.net/latest/pyscript.js"></script>
</head>
<body>
<textarea id="area1" rows="15">print("something")</textarea>
<py-script>
from js import document
def runTextInTag(id):
src = document.getElementById(id).value
exec(src)
</py-script>
<button py-click="runTextInTag('area1')" id="run">Run!</button>
</body>
To address your first example, which changes the innerHTML of the py-script tag itself: A <py-script> tag executes its contained code exactly once, when the custom element is attached to the DOM. This happens shortly after PyScript initializes and the custom HTML element <py-script> is defined, or when you add an additional <py-script> tag to the page.So, in your first example, setting the innerHTML/innerTEXT of a <py-script> tag does not cause that code to be executed again.
You could create a new <py-script> tag with the appropriate innerText and add it to the DOM, at which point its code would be executed, but I think the above method is cleaner for most purposes.

How to import pdf.js using cdn

I wanted to use pdf.js for a project of mine but I faced an issue of importing it, basically, the CDN doesn't work
Here is my code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://cdn.jsdelivr.net/npm/pdfjs-dist#2.7.570/build/pdf.min.js"></script>
</head>
<body>
<canvas id="my-canvas"></canvas>
<script>
pdfjsLib.getDocument('./ahmed.pdf').then(doc => {
console.log("this file has" + doc._pdfInfo.numPages);
});
</script>
</body>
</html>
and that is the errors that my console shows
Deprecated API usage: No "GlobalWorkerOptions.workerSrc" specified.
Uncaught TypeError: pdfjsLib.getDocument(...).then is not a function
So what should i do to solve this problem and thank you so much
You have to set GlobalWorkerOptions.workerSrc to /build/pdf.worker(.min).js of same version:
pdfjsLib.GlobalWorkerOptions.workerSrc =
"https://cdn.jsdelivr.net/npm/pdfjs-dist#2.7.570/build/pdf.worker.min.js"; 👈
pdfjsLib.getDocument('./ahmed.pdf').promise.then(doc => {
console.log(`This document has ${doc._pdfInfo.numPages} pages.");
});
And, as #Pasi has mentioned, you have to promisify .getDocument() by chaining .promise on it. Without it, there is no .then().
See the "Hello World with document load error handling" example on this page to get started: https://mozilla.github.io/pdf.js/examples/
(Your snippet is missing .promise after getDocument() and setting the workerSrc property)

Accessing jQuery within a JavaScript namespace / module pattern [duplicate]

So classic problem, but having a horrible time on finding the actual cause. Typically when I see this error it's because the jQuery reference is after code requiring it, or back jQuery link, or jQuery conflict, etc... so far none of those appear to be the case. Unfortunately seeking out the solution to this problem has lead me to post after post of such cases. I'm sure my problem here is equally as simple, but over an hour of hunting, still no luck...
Edit: Additional information...
The solution file (which I've recreated multiple times trying to figure this out. Is a JavaScript Windows Store Blank App template and I'm doing this in Visual studio. The only references files is Windows Library for javascript 1.0, I have tried deleting this to test as well.
<!DOCTYPE html>
<html lang="en">

<title>HTML5 Canvas Template</title>

<body>
<canvas id="myCanvas" width="500" height="500">

</canvas>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">

It's states that JQuery referred URL is not correct
Try this:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
I tried everything listed above and nothing seems to work until I put this string
<script src="../scripts/jquery-2.2.3.min.js" type="text/javascript"></script>
in the head section of the HTML file. So here's how it looks:
<!DOCTYPE html>
<html>
<head>
<!-- jQuery Reference -->
<script src="../scripts/jquery-2.2.3.min.js" type="text/javascript"></script>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
<title>some title</title>
</head>
<body>
...
And the js file is located at a level below in the folder 'scripts'.
Finally, the error is gone and what a relief!
In my case, the problem was that I was rendering my page over https but I was trying to request the JQuery file over http, which is blocked by many browsers for security reasons.
My fix was to change this...
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
...to this...
<script src="//code.jquery.com/jquery-1.9.1.min.js"></script>
This causes the browser to download JQuery using the same protocol (http or https) as the page being rendered.
Some of my clients had this problem, because apparently they blocked loading Javascript from 3rd party sites. So now I always use the following code to include jQuery:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
window.jQuery ||
document.write('<script type="text/javascript" src="/js/jquery-1.9.1.min.js">\x3C/script>')
</script>
This makes sure, that even if my client blocks loading the Javascript file from the CDN domain, the client still downloads the file from my own server, which is not blocked by the browser.
Anover variant, in my case - I was forced to use proxy. So - IE11--> InternetOptions --> Connections-->LANSettings-Proxy Server--> UseProxyServer - should be checked.
Also check awailability of jQUery script source, my worked variant in VS2012 - -just like in top example
I was getting this same error code:
(Error: 'generateText' is undefined)
...on the code
var bodyText=["The....now."]
I discovered on my text-editor(Notepad++), when typing many lines of text in the directly above the variable bodyText, if I didn't hit return carriage (enter==>WordWrap is off) just kept typing w/o return carriage and let the editor adjust text it worked?
Must be in the settings of Notepad++??

Call composition ready of (edge animate) from javascript

I have a problem in html5 edge animate. I have created an animation using edge animate.
I would like to call composition ready of edge animate from outside. I tried calling using $.Edge.registerCompositionReadyHandler( compId, handlerFn, options ) , But it gave error ReferenceError: $ is not defined . I am not able to solve this and i did not find enough documentation about this. Can any one please help me.
my code looks like this
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>
<title>Untitled</title>
<!--Adobe Edge Runtime-->
<script type="text/javascript" charset="utf-8" src="teste1_edgePreload.js"></script>
<script type="text/javascript" src="teste1_resize.js"></script>
<style>
.edgeLoad-EDGE-1429726 { visibility:hidden; }
</style>
<!--Adobe Edge Runtime End-->
<script>
$.Edge.registerCompositionReadyHandler("EDGE-1429726",scaleStage) //SCALE STAGE IS INSIDE THE JAVASCRIPT fn teste1_resize.js
function mover(){
var stage = $.Edge.getComposition("EDGE-1429726").getStage();
console.log($("#Stage").height());
stage.mover();
}
</script>
</head>
<body style="margin:0;padding:0;">
<div id="Stage" class="EDGE-1429726">
<input type="button" value="Mover" onClick="mover();">
</div>
</body>
Thanks in ADVANCE
With Ena's help and little modification i was able to find an answer.
AdobeEdge.bootstrapCallback(function(compId) {
AdobeEdge.Symbol.bindElementAction(compId, 'stage', 'document', 'compositionReady', function(sym, e){
// composition is loaded, do stuff here
});
});
Instead of
$.Edge.registerCompositionReadyHandler
use
AdobeEdge.registerCompositionReadyHandler
Moreover, put your code inside this function:
AdobeEdge.bootstrapCallback(function(compId) {
// Register your handlers here
});
So you are sure the stage is loaded and you can register handlers in it.
