Populate a javascript array shorthand for keys like php

In Javascript, know I can set an array so that the key is a autonumbered (starting at 0) assigned array:

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

// Key for Sunday is '0'

and if I want to assign keys, I could do:

    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'

But is there a shorthand way to assign the keys like in PHP?

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

// Doesn't work
Solution

  • What you want is an object:

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

    You can then get "Sunday" like this:

    var sunday = d_names[5];
