开发王代码 代码

<script type="text/javascript">
  var a = new Array();
  Inner:
  for (var i = 0; i < 5; i++){  
    if (i == 2){
      //如果i等于2就跳到Inner继续执行，这样第三列就没有赋值
      continue Inner;
    }else{
      a[i] = i + 1;
    }
  }
  var s = "";
  //遍历数组元素
  for (var j = 0; j < 5; j++){
    s += a[j] + "\n";
  }
  document.write(s);
</script>
