Twitch, jquery and my URL

HI
Can i send some data from extensions to my sql server and get response?
I try it but its not working…

html:

<div id="response"> </div>
<input name='a1' id='a1'>
<button id='ddd'>send</button>

Javascript

  $("#ddd").click(function(){
var ra1 = document.getElementById("a1").value; 
$.ajax({
     type: 'post',
     url: 'https://www.my-web.eu/re.php',
     data: { a1:  ra1 },
     success: function (res) {
document.getElementById('response').innerHTML=res;

Thanks

Well what does it say in the console?

This looks like a general “I don’t know Javascript” than an extensions problem?

I allow adress https://code.jquery.com/ on Whitelist URL

I open it on inspect mode

and have this error:
Refused to load the script ‘https://code.jquery.com/jquery-1.10.2.js’ because it violates the following Content Security Policy directive: “script-src ‘self’ https://5ephiv0mjp98oz8s03oasxh6oot00o.ext-twitch.tv https://extension-files.twitch.tv https://www.google-analytics.com”. Note that ‘script-src-elem’ was not explicitly set, so ‘script-src’ is used as a fallback.

and then my main script.js have error :
Uncaught ReferenceError: $ is not defined
at script4.js:1

Can I allow JQUERY?

Thanks

You cannot use external JS in extensions.

All JS (except the TwitchExt JS Helper and Google Analytics) must be included in your local bundle.

See section 2 - https://dev.twitch.tv/docs/extensions/guidelines-and-policies
Specifically 2.8

The Allowlist is for allowing you to display functioning <a href="somesite"> links not for external library includes

Thank. I find it and give thats links as file and it works.
