使用变量获取数组属性值

Question

var type = "chance"; //or "chest" ;
var title = cards.type[0].title; //type is variable not an actual property of cards

而不是键入我想要使用变量的属性名称，因为它可以是cards.chance[0].title或cards.chest[0].title

Answer 1

尝试[]语法：

var type = "chance"; //or "chest" ;
var title = cards[type][0].title;
