<script>
window.onload = function(){ 
  function parent(age,name){ 
   this.age = age; 
   this.name = name; 
  } 
  parent.prototype.show = function(){ 
   alert('父级方法'); 
  } 
  function child(age,name,job){ 
    parent.apply(this,arguments); 
    this.job = job; 
  } 
  (function(){ 
    for(var i in parent.prototype){ 
    child.prototype<i>=parent.prototype<i> 
  } 
  })(); 
  var b = new parent(14,'侠客行'); 
  var a = new child(15,'狼侠','侠客');
