xhttp | Tiny shortcuts for using the native fetch API | HTTP library

I am new to using promises in javascript and I just cannot seem to get something that (I think) should be fairly basic working.

I am writing code for a turn-based game where during a player's turn, a number of things happen of which some are asynchronous (for example animations using setInterval), while some are vanilla synchronous code. What I am trying to do is to determine when ALL of the functions required during a player's turn have completed, so that I can switch turns to the next player. The client side is pure HTML5/CSS/JS (using the canvas API for animation), while the back-end is PHP 8.1 and MySQL5.6 in case it matters.

The relevant functions of my current code look like this:

I have this javascript

I am just starting with react-native to create one app for android cel. I have a form with 2 fields / and I want to load those fields from json that I pull from php file. If I send only one value through json I can load that value in one field using "componentDidMount" and "XMLHttpRequest()" This is the code I am using at componentdidmount:

In my php page I have a row of buttons which each have some values (5 in this example). These values shall be send into a ajax script which do some calculation to values and return the result for each button without reloading the homepage. In this example the result will be

FRANK=5 (button 1)

FRANK=frank (button 2)

FRANK=48 (button 3)

FRANK=Bo (button 4)

FRANK=test (button 5)

When I press the first button I should see result 1 on the button. When I press the next button I should see result 2 on the button.

I only have one result returned on button 1 since all buttons has the same container for the return value. I need more containers for return values and I could add $i to the container: . This will give me different containers to return the result to. But how can I use $i in the javascript. My problem is also that var x in the javascript always will be the value from the first button. Again I could add $i to the id="x": id="x'.$i.'" but still I only have document.getElementById("x").value to read the x value in the javascript.

I hope that somebody help me to finish the code here.

I have a JS script embedded in another website. the target is to gram field contact and post it. my problem is that the script runs well on safari browser but not with chrome browser.

I tried: -clear cache on browsers

• clear server Cache
• clear Cloudflare Cache
• checked that the file is reachable
• no error on console

also tried to put alert to see the script is running. works of safari and do not show the alert in chrome even in incognito mode

here is the code:

I'm trying to post form data though a POST AJAX call in JavaScript for a chat system I'm creating, how come the following is not working? I tried to get some documentation but I cannot find it.

I am creating a website and I need to make a backend POST server. I have created 90% of it, but the issue I am facing is that I need to send JSON as well as a pdf (normally sent by multipart/form-data, but would need a different route). What I am trying to do is transform the file into base64string, send it over in a request, and then restore it back and write it to a file. This whole thing happens, and the PDF even returns scrambled data, but the PDF is just a blank page when written down even after being converted back to binary and being written
HTML-side JS code:

Unable to get value from json response Here is my html.

index html

How do I retrieve the response time for a request like this..
