单向链表JS实现
可以排序，增加，查找，删除的单向链表
function linkNode(_key, _value)
{
/// <summary>
/// 链表类的节点类
/// </summary>
this.Key = _key;
this.Value = _value;
this.next = null;
}
function Link()
{
/// <summary>
/// 创建一个链表类
/// </summary>
this.root = new linkNode(null, null); //root永远是个空节点
this.end = this.root;
}
Link.prototype =
{
count: 0,
value: function (_key)
{
