js里的prototype使用示例

 
<script type="text/javascript"> 
function people(name){ 
this.name=name; 
this.introduce=function(){ //对象方法 
alert("my name is"+this.name); 
} 
} 

people.run=function(){ //类方法 
alert("i can run"); 
} 

people.prototype.jump=function(){ //原型方法 
alert("i can jump") 
} 

var p1=new people("vincent"); 
p1.introduce(); 
people.run(); //c#中的static 
p1.jump(); 
</script> 

 
function common(){ 
//..... 
} 
common.prototype=new Object();
