はじめに

Apache RoyaleでのJavaScriptのAPIの使い方を簡単にまとめます。

普通に利用できるAPI

alert、console.log、等は普通に利用できる

alert("Hello World");

console.log("Hello World");

windowを使って利用できるAPI

fetch、localStorage、等はwindowから取得することで利用できる

window["fetch"]("http://localhost:3000/xxx")
    .then(function(response:Object):Object {
        return response.json();
    }).then(function(jsonObject:Object):void {
        console.log(JSON.stringify(jsonObject));
    });

window["localStorage"].setItem("test-key", "Hello World");
