JavaScriptで次のような二次元配列を設定する方法。

img_ary[0][0] = ‘花’
img_ary[0][1] = ‘http://sample.com/java/flower.jpg’
img_ary[1][0] = ‘鳥’
img_ary[1][1] = ‘http://sample.com/java/bard.jpg’
img_ary[2][0] = ‘アザラシ’
img_ary[2][1] = ‘http://sample.com/java/seal.jpg’

リテラルで設定する場合

var img_ary = [['花','http://sample.com/java/flower.jpg'],
              ['鳥','http://sample.com/java/bard.jpg'],
              ['アザラシ','http://sample.com/java/seal.jpg']];

代入で設定する場合

var img_ary = [];
中略
img_ary[0] = new Array('花','http://sample.com/java/flower.jpg');
img_ary[1] = new Array('鳥','http://sample.com/java/bard.jpg');
img_ary[2] = new Array('アザラシ','http://sample.com/java/seal.jpg');

もしくは
var img_ary = [];
中略
img_ary[0] = new Array();
img_ary[0][0] = '花';
img_ary[0][1] = 'http://sample.com/java/flower.jpg';
img_ary[1] = new Array();
img_ary[1][0] = '鳥';
img_ary[1][1] = 'http://sample.com/java/bard.jpg';
img_ary[2] = new Array();
img_ary[2][0] = 'アザラシ';
img_ary[2][1] = 'http://sample.com/java/seal.jpg';
