Multidimensional array

Recommended Posts

Why doesn't this work?

 

var candy = new Array(new Array());
for (var i = 0; i < 10; i++) {
    candy[i][i] = "Sweet!";
  }

 

The error that I get from chrome is:

Uncaught TypeError: Cannot set property '0' of undefined

 

I want to make an multidimensional array in an loop without knowing how long it can be.

Because you only declare the index candy[ 0 ] as array, candy[ 1 ] is not defined.

You can simply declare the arrays in your loop

var candy = [];
for (var i=0; i<10; i++){
    candy[i] = [];
    candy[i][i] = 'Sweet!';
}
