以下是螺旋图案的代码示例:
case 'spiral':
$('.block', grid).css({
'opacity': 0
});
var order = new Array();
var rows2 = rows/2, x, y, z, n=0;
for (z = 0; z < rows2; z++){
y = z;
for (x = z; x < cols - z - 1; x++) {
order[n++] = y * cols + x;
}
x = cols - z - 1;
for (y = z; y < rows - z - 1; y++) {
order[n++] = y * cols + x;
}
y = rows - z - 1;
for (x = cols - z - 1; x > z; x--) {
order[n++] = y * cols + x;
}
x = z;
for (y = rows - z - 1; y > z; y--) {
order[n++] = y * cols + x;
}
}
for (var m = 0; m < n; m++) {
$('.block-' + order[m], grid).stop().delay(100*m).animate({
opacity: 1
}, {
duration: 420,
complete: (m != n - 1) ||
function () {
alert('done');
}
});
}
break;

我还改进了您的“随机”动画,以显示所有方块,而不仅仅是一个子集。代码是:
case 'random':
var order = new Array();
var numbers = new Array();
var x, y, n=0, m=0, ncells = rows*cols;
for (y = 0; y < rows; y++){
for (x = 0; x < cols; x++){
numbers[n] = n++;
}
}
while(m < ncells){
n = Math.floor(Math.random()*ncells);
if (numbers[n] != -1){
order[m++] = n;
numbers[n] = -1;
}
}
$('.block', grid).css({
'opacity': 0
});
for (var m = 0; m < ncells; m++) {
$('.block-' + order[m], grid).stop().delay(100*m).animate({
opacity: 1
}, {
duration: 420,
complete: (m != ncells - 1) ||
function () {
alert('done');
}
});
}
break;
