<script type="text/javascript">
  <!--
  var myArray = new Array("Tom","Tommy","John");
  //按照ASCII字符顺序进行升序排列
  myArray.sort(); //myArrray = ["John","Tom","Tommy"]
  var sortFn = function(a,b){
    if (a.length < b.length) return -1;
    if (a.length > b.length) return 1;
    if (a.length == b.length) return 0;
  }
  //按照自定义函数进行排序，自定义函数是根据元素字符串长度进行对比的
  myArray.sort(sortFn); //myArrray = ["Tom","John","Tommy"]
