Screenshots
You can now select Simplified Chinese from the setting tab.
UI will be updated to Chinese immediately once you click Save.
You can enter each line any two crytocurrency separated by a space.
And when APP is loaded, it will call coinmarkcap API to convert, for example:
Javascript Async and Await to Convert from one coin to another
// ajax calling API
const getPriceOfUSD = (coin) => {
return new Promise((resolve, reject) => {
let api = "https://api.coinmarketcap.com/v1/ticker/" + coin + '/';
fetch(api, {mode: 'cors'}).then(validateResponse).then(readResponseAsJSON).then(function(result) {
resolve(result[0].price_usd);
});
});
}
// ajax get conversion
const getConversion = async(coin1, coin2) => {
let api1 = getPriceOfUSD(coin1);
let api2 = getPriceOfUSD(coin2);
return await api1 / await api2;
}
// conversion
const processConversion = (s) => {
let arr = s.trim().split("\n");
for (let i = 0; i < arr.length; i ++) {
let pair = arr[i].split(" ");
if (pair.length == 2) {
let a = pair[0].trim().toLowerCase();
let b = pair[1].trim().toLowerCase();
var pat = /^[a-zA-Z\-]+$/;
if (pat.test(a) && pat.test(b)) {
let dom = $('div#conversion_results');
let dom_id = "convert_" + a.replace("-", "") + "_" + b.replace("-", "");
dom.append('<div id="' + dom_id + '"> </div>');
getConversion(a, b).then(x => {
$('div#' + dom_id).html("<h4>1 " + a.toUpperCase() + " = <span class=yellow>" + x + "</span> " + b.toUpperCase() + "</h4>");
});
}
}
}
}
