JavaScript实现的链表数据结构实例_javascript技巧

function GenericList(){
this.head=null;
this.current=null;
//打出所有的链表结点
this.print= function(){
this.current=this.head;
while(this.current!=null){
alert(this.current.data);
this.current=this.current.next;
}

},
//建立链表
this.addHead =function(t){


var node=new Node();
node.data=t;
node.next=this.head;
this.head=node;

}

}

function SortList(){
//冒泡排序链表
this.BubbleSort=function()
{
if(this.head==null||this.head.next==null)
{
return ;
}
var swapped;
do{

this.previous=null;
this.current=this.head;

var swapped=false;
while(this.current.next!=null)
{

if(this.current.data-this.current.next.data>0)
{

var tmp=this.current.next;
this.current.next=this.current.next.next;
tmp.next=this.current;
if(this.previous==null)
{
this.head=tmp;
}
else
{
this.previous.next=tmp;
}
this.previous=tmp;
swapped=true;


}
else
{

this.previous=this.current;
this.current=this.current.next;

}

}



}while(swapped);

}

}

SortList.prototype=new GenericList();

(function Main(){
var sl=new SortList();
for(var i=0;i {sl.addHead(arguments[i]);
}
alert("未排序的链表");
sl.print();
sl.BubbleSort();
alert("已排序的链表 从小到大");
sl.print();

})("1","2","3","4")
