How to remove a country from intl-tel-input

(new in javascript)

I am asked to remove a country (China) from the dropdown menu of the plugin intl-tel-input

the code below displays the dropdown menu and it looks that it calls the utils.js file to retain the countries

var iti = window.intlTelInput(input,
            {
                utilsScript: '@Url.Content("~/Scripts/lib/intl-tel-input/utils.js")',
                separateDialCode: false,
                hiddenInput: "mobileNumber",
                preferredCountries: ["lu", "gb","fr","in","us","de"],
            });

I found the Chinese prefix and I removed from the utils.js file which it looks like the below:

A part of the code (because the code is huge)

var K={1:"US AG AI AS BB BM BS CA DM DO GD GU JM KN KY LC MP MS PR SX TC TT VC VG VI".split(" "),7:["RU","KZ"],20:["EG"],27:["ZA"],30:["GR"],31:["NL"],32:["BE"],33:["FR"],34:["ES"],36:["HU"],39:["IT","VA"],40:["RO"],41:["CH"],43:["AT"],44:["GB","GG","IM","JE"],45:["DK"],46:["SE"],47:["NO","SJ"],48:["PL"],49:["DE"],51:["PE"],52:["MX"],53:["CU"],54:["AR"],55:["BR"],56:["CL"],57:["CO"],58:["VE"],60:["MY"],61:["AU","CC","CX"],62:["ID"],63:["PH"],64:["NZ"],65:["SG"],66:["TH"],81:["JP"],82:["KR"],84:["VN"],90:["TR"],91:["IN"],92:["PK"],93:["AF"],94:["LK"],95:["MM"],98:["IR"],211:["SS"],212:["MA","EH"],213:["DZ"],216:["TN"],218:["LY"],220:["GM"],221:["SN"],222:["MR"],223:["ML"],224:["GN"],225:["CI"],226:["BF"],227:["NE"],228:["TG"],229:["BJ"],230:["MU"],231:["LR"],232:["SL"],233:["GH"],234:["NG"],235:["TD"],236:["CF"],237:["CM"],238:["CV"],239:["ST"],240:["GQ"],241:["GA"],242:["CG"],243:["CD"],244:["AO"],245:["GW"],246:["IO"],247:["AC"],248:["SC"],249:["SD"],250:["RW"],251:["ET"],252:["SO"],

but it doesnt work. The Chinese prefix is still there.

Can someone help please?

If you take a look at the intl-tel-input documentation regarding Initialisation Options. There is an option called excludeCountries.

We can modify your initialisation code to include this option to exclude China:

var iti = window.intlTelInput(input,
    {
        utilsScript: '@Url.Content("~/Scripts/lib/intl-tel-input/utils.js")',
        separateDialCode: false,
        hiddenInput: "mobileNumber",
        preferredCountries: ["lu", "gb", "fr", "in", "us", "de"],
        excludeCountries: ["cn"]
    });
