为php这样的键填充javascript数组的简写

Question

在Javascript中,知道我可以设置一个数组,以便键是自动编号(从0开始)分配的数组:

var d_names = new Array("Sunday", "Monday", "Tuesday", 
              "Wednesday", "Thursday", "Friday", "Saturday");

// Key for Sunday is '0' 

如果我想分配密钥,我可以这样做:

    var d_names={};
    d_names[5]="Sunday";
    d_names[6]="Monday";
    d_names[7]="Tuesday";
    d_names[8]="Wednesday";
    d_names[9]="Thursday";
    d_names[10]="Friday";
    d_names[11]="Saturday";

    // Key for Sunday is '5'

但有没有像PHP中那样分配键的简写方法？

var d_names = new Array(5=>"Sunday", 6=>"Monday", 7=>"Tuesday", 8=>"Wednesday", 
            9=>"Thursday", 10=>"Friday", 11=>"Saturday"); 

// Doesn't work

Answer 1

你想要的是一个对象:

var d_names = {
    5: "Sunday",
    6: "Monday"
    //...
};

然后你可以"Sunday"这样:

var sunday = d_names[5];
