Javascript Array inside Array - how can I call the child array name?

Question

Here is the example of what I am doing:

   var size = new Array("S", "M", "L", "XL", "XXL");
   var color =          


        

Answer 1

You've made an array of arrays (multidimensional), so options[0] in this case is the size array. you need to reference the first element of the child, which for you is: options[0][0].

If you wanted to loop through all entries you can use the for .. in ... syntax which is described here.

var a = [1,2,4,5,120,12];
for (var val in t) {
    console.log(t[val]);
}

var b = ['S','M','L'];
var both = [a,b];

for (var val in both) {
     for(val2 in both[val]){console.log(both[val][val2])}
}
