An instance of a linked list data structure implemented by JavaScript

This example is javascript to build a linked list.
And sorted it out.

You can also extend on linked lists like GenericList1.
Achieve a variety of sorting and add, delete, change nodes.

function Node(){

  this.data=null;

  this.next=null;

}
function GenericList(){

  this.head=null;

  this.current=null; 

  // Type all the list nodes 

  this.print= function(){

  this.current=this.head;

   while(this.current!=null){

      alert(this.current.data);

      this.current=this.current.next;

    }

  

  },

  // Build list 

  this.addHead =function(t){

      

  

      var node=new Node();

      node.data=t;

      node.next=this.head;

      this.head=node;

 

  }

  

 
}


function SortList(){

// Bubble sort linked lists  

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<arguments.length;i++)

 {sl.addHead(arguments[i]);

 }

 alert(" Unsorted linked list ");

 sl.print();

 sl.BubbleSort();

  alert(" Sorted linked list    Since the childhood ");

 sl.print();
})("1","2","3","4")
