Question

I have an array that stores the values:

var array = [['favorite color'],['black','red']]

to get black I would:

document.write(array[0][1][0]);

then if i append to the array another question [['favorite thing']['box','ball']]

If I wanted ball I would:

document.write.array[1][1][1];

I am having trouble understanding arrays. I want an array with one question and multiple answers then I want to loop through them and display everything. I can do the loop but I am unsure how to find things in nested arrays once I create them.

Answer 1

Use a combination of objects (which work like dictionaries) and arrays. For example:

var array = [ 
  {'question' : 'favorite color', 'choices' : ['black','red'] },
  {'question' : 'favorite thing', 'choices' : ['box','ball'] }
]

for( var i = 0; i < array.length; i++ ) {
    var question = array[i]['question'];
    var choices = array[i]['choices'];

    // here you can display / write out the questions and choices
}

Bearing in mind, creating a class and using a constructor or init methods would probably be better to encapsulate the idea of questions and answers. But the above is the basic idea.
