开发王代码 代码

<script type="text/javascript">
  var twoDArray = new Array(new Array("one", "two"), new Array("three", "four"));
  //这里用到了Array对象的属性length，它可以计算数组的元素数
  var outerArrayLength = twoDArray.length;
  for (i=0; i<outerArrayLength; i++) {
	var innerArrayLength = twoDArray[i].length;
	for (j=0; j<innerArrayLength; j++) {
		document.write(twoDArray[i][j] + "<br />");
	}
  }
</script>
