javascript - How to process the data returned by the server without submitting a get request with a custom xhr?

Question

Prerequisite: The server can already process this get request and return the required data. I would like to ask: If this code is used in the HTML page to make a get request to the server: {code...} Then after the get request is sent, how can I obtain and process the data returned by the server as soon as the data is returned? ..

A method similar to jsonp, except that jsonp is mainly used to implement cross-domain calls.

I came here for a walk around while at work. I was short on time and did not deploy the server part.

The principle is to use script tags and src attributes to set the interface address, let the server assemble the data, and return JavaScript code snippets.

index.html

Server returns data

(function(callback) {
    var someData = {a: 1, b:2};
    callback(someData);
})(test);
