変数と文字列を組み合わせた変数を変数で使いたい ### var Over = "Overrrrr" var Page = "Stack" + Over + "Flow" JSON.parse(httpObj.response).Ids.find((v) => v.User == "Overrrrr"); JSON.parse(httpObj.response).Ids.find((v) => v.User == Over); JSON.parse(httpObj.response).Ids.find((v) => v.User == Over).StackOverrrrrFlow; JSON.parse(httpObj.response).Ids.find((v) => v.User == Over).Page; `.StackOverrrrrFlow``.Page` ### JSON.parse(httpObj.response).Ids.find((v) => v.User == "Overrrrr"); // Object { User: Overrrrr, Id: "82955", StackOverrrrrFlow: "DOTCOM" } JSON.parse(httpObj.response).Ids.find((v) => v.User == Over); // Object { User: Overrrrr, Id: "82955", StackOverrrrrFlow: "DOTCOM" } JSON.parse(httpObj.response).Ids.find((v) => v.User == Over).StackOverrrrrFlow; // "DOTCOM" JSON.parse(httpObj.response).Ids.find((v) => v.User == Over).Page; // undefined `"DOTCOM"`

JSON.parse(httpObj.response).Ids.find((v) => v.User == Over)[Page];
