为什么打印不出来呢？难道不可以多重嵌套么？
<script>
var myarr = new Array();
for (var x = 1; x < 10; x++) {
myarr[x] = new Array();
for (var m = 1; m < 5; m++) {
myarr[m] = new Array();
for (var q = 1; q < 10; q++) {
myarr[x][m][q] = x + q + m;
document.write(x + "+" + q + "+"+m+"=" + myarr[x][m][q] + "<br/>");
}
}
}
</script>
