我试图为孩子们做一个拖放测验。
我有3 letters
,他们必须将其放在3 boxes
中才能说出来。我使用jQuery
,不知怎的,我无法修改此代码以显示图片。我想,我需要制作一个two dimensional array
,但我不知道如何访问它并显示图片,还要添加这些内容for..loop
,
this is the whole code

我想放图片而不是我试过的数字
for ( var i=0; i<3; i++ ) {
$('<div>' + numbers[i] + '</div>').data( 'number', numbers[i] ).attr( 'id', 'card'+numbers[i] ).appendTo( '#cardPile' ).draggable( {
containment: '#content',
stack: '#cardPile div',
cursor: 'move',
revert: true
} );
}
但它给了我相同的图片3次相同的图片..我想要3张不同字母的图片
