<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>面向對象繼承實例</title>
<script type="text/javascript">
window.onload = function(){
function parent(age,name){
this.age = age;
this.name = name;
}
parent.prototype.show = function(){
alert('父級方法');
}
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,'俠客行');
var a = new child(15,'狼俠','俠客');
a.show();
}
</script>
</head>
