This time I will bring you a detailed explanation of the use of js linked lists, what are the precautions when using js linked lists, the following is a practical case, let's take a look.

As shown below:

<!doctype html>
<html lang="en">
 <head>
 <meta charset="UTF-8">
 <title>Document</title>
 <script>
  function Node(v){
    this.value=v;
    this.next=null;
  }
  function ArrayList(){
    this.head=new Node(null);
    this.tail = this.head;
    this.append=function(v){
      node = new Node(v);
      this.tail.next=node;
      this.tail=node;
    }
    this.insertAt=function(ii,v){
      node = new Node(v);
      //找到位置的节点
      tempNode=this.head;
      for(i=0;i<ii;i++){
        if(tempNode.next!=null){
          tempNode=tempNode.next;
        }else{
          break;
        }
      }
      node.next=tempNode.next;
      tempNode.next = node;
    }
    this.removeAt=function(ii){
      node1=this.head; //要删除节点的前一个节点
      for(i=0;i<ii;i++){
        if(node1.next!=null){
          node1=node1.next;
        }else{
          break;
        }
      }
      node2=node1.next;  //要删除的节点
      if(node2!=null){
        node1.next = node2.next;
        if(node2.next==null){
          this.tail=node1;
        }
      }
    }
    
  }
  function Iterator(arryList){
    this.point=arryList.head;
    this.hasNext=function(){
      if(this.point.next!=null){
        this.point=this.point.next;
        return true;
      }else{
        return false;
      }
    }
    this.next=function(){
      return this.point.value;
    }
  }
  
  var arry = new ArrayList();
  arry.append(1);
  arry.append(2);
  arry.append(3);
  arry.insertAt(1,8);
  arry.insertAt(0,9);
  arry.insertAt(100,100);
  arry.insertAt(1000,1000);
  arry.insertAt(1,200);
  arry.insertAt(200,2000);
  
  iterator = new Iterator(arry);
  while(iterator.hasNext()){
    document.write(iterator.next());
    document.write(&#39;<br/>');
  }
 </script>
 </head>
 <body>
 
 </body>
</html>；
