let mapArs = new Map();var k1 = 1;var k2 = 2;var k3 = 3;mapArs.set(k1, ["name", "小明"]);mapArs.set(k2, ["title", "Author"]);mapArs.set(k3, ["content", "內容"]);//console.log(mapArs.get(k1));[...mapArs].map( function(mapAr){ //console.log(mapAr); });[...mapArs].map( function(value, key, map){ console.log(value+'卍[key]='+key+'==map='+map); })
使用function(value, key, map){}函數輸出 name,小明、title
