You can combine basic array/object functions to archive your goal. But as i commented on your question, you should define strict filter criterias.
const data = {
"ip": "103.26.208.254",
"version": "IPv4",
"city": "Jakarta",
"region": "Jakarta",
"region_code": "JK",
"country": "ID",
"country_name": "Indonesia",
"country_code": "ID",
"country_code_iso3": "IDN",
"country_capital": "Jakarta",
"country_tld": ".id",
"continent_code": "AS",
"in_eu": false,
"postal": null,
"latitude": -6.1741,
"longitude": 106.8296,
"timezone": "Asia/Jakarta",
"utc_offset": "+0700",
"country_calling_code": "+62",
"currency": "IDR",
"currency_name": "Rupiah",
"languages": "id,en,nl,jv",
"country_area": 1919440.0,
"country_population": 267663435.0,
"asn": "AS18103",
"org": "Neuviz Net"
};
// create a regex of each filter value
const filters = [
"republik",
"telekomunikasi",
"fastnet", "indosatm2",
"telekomunikasi", "indosat",
"cyberindo", "biznet", "xl",
"telematika", "hutchison",
"smartfren", "mnc",
"wireless indonesia",
"antar nusa", "biznet",
"ezecom", "win", "axis",
"linknet-fastnet", "indonesia",
"bali", "linknet", "indosat",
"antar nusa", "indo", "firstmedia",
"s.i", "cambodia", "neuviz"
].map((v) => {
return new RegExp(`${v}`, "gi");
});
// get array of values from object
// filter array based on the test criteria
let matches = Object.values(data).filter((v) => {
// conver every value to astring
let value = String(v).toLowerCase();
// test each filter on value
return filters.some((filter) => {
// test the regular expression on the value
return filter.test(value);
});
});
if (matches.length > 0) {
console.log("Filter matched!", matches);
} else {
console.log("Filte *not* matched")
}The code is well documented, if you dont understand a snippet/chunk, let me know. If it dosnt work like expected, let me know too!
Happy coding!

anyway , i think this "const / let" doesnt work well with android app, because im trying to build android app webview and its not working , but on browser its work perfectly..

@KuroyukiHime You didnt mention that anywhere, but feel free to change this to
var or whatever you like.Kuroyuki Hime
can you show me how ? because im not really good at javascript .. thanks for your help.

As i have written, just use
var instead of const / let...Arrays in JavaScript have some in-build methods which you can do specific tasks with, like the some method in which you can check if one or more parts of the ISP names are partly in the list. It will return true or false which you can use to determine the text of your $("#ip") element.
$.getJSON("https://ipapi.co/json/", function (data) {
// Create a list of organizations.
var organizations = ["republik","telekomunikasi","fastnet","indosatm2","telekomunikasi","indosat","cyberindo","biznet","xl","telematika","hutchison","smartfren","mnc","wireless indonesia","antar nusa","biznet","ezecom","win","axis","linknet-fastnet","indonesia","bali","linknet","indosat","antar nusa","indo","firstmedia","s.i","cambodia","neuviz"];
// Lowercased version of the ISP.
var isp = data.org.toLowerCase();
// Check if the lowercased ISP occurs in any of the organizations.
var orgExists = organizations.some(org => org.includes(isp));
// Ternary if statement.
// If orgExists === true, text will be "exist: " + isp.
// Otherwise text will be "no exist".
var text = orgExists ? "exist: " + isp : "no exist";
// Output the text.
$("#ip").text(text);
});
=="filter", but your right. Would be difficult so.
