How can I choose an object key at random?

Question

I have the following code;

namedarray[\'India\']=\'New Delhi\';
namedarray[\'Australia\']=\'Canberra\';
namedarray[\'Indonasia\']=\'Jakarta\';
namedarray[\'I         


        

Answer 1

I would just use two arrays for the data.

var countries = ['India', 'Australia', 'Indonasia', ... ];
var capitols = ['New Delhi', 'Canberra', 'Jakarta', ...];

Then insert into your text with:

var index = Math.floor(Math.random() * capitols.length);
document.getElementById('question').innerHTML="Q." +capitols[index]+"  is capital for which country";

You can then use the index variable to look up the answer later on as well.
