I don't know Cesium, but a quick search told me that it has a [loadJson](https://cesium.com/downloads/cesiumjs/releases/b29/Documentation/loadJson.html) feature that will do just about the same as `$.ajax`, without the trouble of having to get jQuery working. — Peter B, Dec 23 '21 at 12:56
Does this answer your question? [JQuery - $ is not defined](https://stackoverflow.com/questions/2194992/jquery-is-not-defined) — Liam, Dec 24 '21 at 09:06
no, im still struggling :/ @Liam The problem is something related about Sandcastle, because for example in replit.com IDE works everything fine. So it is my lack of competence about Sandcastle — user17603839, Dec 24 '21 at 12:51
It would probably help if you included the [tag:sandcastle] tag then — Liam, Dec 24 '21 at 13:24
Is there a reason you don't just do [what is suggest here?](https://stackoverflow.com/questions/70461880/cesium-error-referenceerror-is-not-defined-writing-in-sandcastle?noredirect=1#comment124556306_70461880). In 2021/2022 you really don't need jquery — Liam, Dec 24 '21 at 13:25
Or even use the native [`XMLHttpRequest`](https://developer.mozilla.org/en-US/docs/Web/Guide/AJAX/Getting_Started). without using an libraries at all — Liam, Dec 24 '21 at 13:26

Cesium's "Sandcastle" test environment does not include a means to include JQuery. Instead, you can use Cesium's own helper functions for things like this, such as Cesium.Resource.fetchJson.

For example: Live Sandcastle Demo

var viewer = new Cesium.Viewer("cesiumContainer");

Cesium.Resource.fetchJson({
  url: "https://reqres.in/api/unknown/2"
}).then(data => {
  console.log(JSON.stringify(data, null, '    '));
});
