Javascript 实现 goto

<script type="text/javascript">
 test1 : for (var i = 0; i < 3; i++) {
    test2 : for (var j = 0; j < 3; j++) {
       if (i == 1 && j == 1) {
          continue test1;
       } else {
          alert("i = " + i + ", j = " + j);
       }
    }
 }
 /*Output is:
       "i = 0, j = 0"
       "i = 0, j = 1"
       "i = 0, j = 2"
       "i = 1, j = 0"
       "i = 2, j = 0"
       "i = 2, j = 1"
       "i = 2, j = 2"
       Notice how it skips both "i = 1, j = 1" and "i = 1, j = 2"*/
