Question

I writing this, because it’s driving me crazy, and I don’t know how its possible:

My code

var categories = new Array(length);
    for (i = 0; i < length; ++i)
    {categories[i] = new Array (2);}
    $(".lang-box").each(function(i) {
      if( i < categories.length) {categories[i][0] = $(this).attr('name');categories[i][1] = $(this).val();}
    });

How is it possible if I do:

console.log(categories.lenght);

I get “undefined”, but if I do

console.log(categories);

I get:

[ ["pl","fwer"],["en",""]]

How is this possible?

Answer 1

Simple fix. If you change

console.log(categories.lenght);

… to …

console.log(categories.length);

it should work fine.
