简陋的斗地主，js实现

最近闲了两天没事做，用js写了个斗地主，练习练习。代码和功能都很简陋，还有bug，咋只是聊聊自己的思路。

这里说说斗地主主要包含的功能：洗牌，发牌，玩家出牌、电脑出牌，出牌规则的验证，输赢啥的没有判断，只是实现了这几个主要功能，下面依次说说几个功能的实现：

　　1.洗牌：

　　　　

var pukes=this.manage.pukes;//存放扑克牌的数组
//洗牌
for(var i=0;i<pukes.length;i++){
        var tmp=pukes[i];
        var index=util.random(i,pukes.length);//随机交换两张牌
        pukes[i]=pukes[index];
        pukes[index]=tmp;
}    

　　2.发牌（简版默认是玩家自己为地主，电脑为农民），由于前面洗牌时已经将牌的顺序打乱，所以发牌只是简单的循环把pukes中的元素添加到每个玩家实例中的pukes字段中。

//发牌
    var start=0;
    for(var i=0;i<this.manage.pukes.length-3;i++) {
        if(start==this.manage.players.length){
            start=0;
        }
        this.manage.pukes[i].status=true;
        this.manage.players[start].pukesLen++;
        this.manage.players[start++].pukes.push(this.manage.pukes[i]);
    }
    for(var i=this.manage.pukes.length-3;i<this.manage.pukes.length;i++){
        //地主多三张
        this.manage.pukes[i].status=true;
        this.manage.players[this.manage.curPlayerIndex].pukesLen++;
        this.manage.players[this.manage.curPlayerIndex].pukes.push(this.manage.pukes[i]);
    }

　　3.玩家出牌，玩家出牌分为电脑和玩家自己两个步骤，电脑出牌是非常傻瓜的出牌方式（有牌就出）：

　　

//出牌
    if(this.options.playerIndex==this.manage.curPlayerIndex) {
        var spks = [],gz=false;

        if (this.manage.curMaxPlayerIndex == this.options.playerIndex) {
            this.manage.deskPukes = [];
        }
        if (this.isCompute) {
            //电脑自动出牌
            var start = 0;
            var len=this.manage.deskPukes.length||1;
            while (start < this.pukes.length) {
                spks = [];
                for (var i = 0,j=start; i <len&&j<this.pukes.length; i++) {
                    //随便选一张 可以出就行
                    if(this.pukes[j].status) {
                        spks.push(this.pukes[j++]);
                    }
                }
                if(spks.length) {
                    if (rules.valids(spks, this.manage.deskPukes)) {
                        gz = true;
                        break;
                    }
                }
                start++;
            }
        }
        else {
            //玩家选择出牌
            for (var i = 0; i < this.pukes.length; i++) {
                if (this.pukes[i].selected && this.pukes[i].status) {
                    spks.push(this.pukes[i]);
                }
            }
            if (rules.valids(spks, this.manage.deskPukes)) {
                gz=true;
            }
            else{
                alert("出牌不符合规则！");
            }
        }
        if(gz){
            this.manage.curMaxPlayerIndex=this.options.playerIndex;
            this.manage.deskPukes = [];
            for (var i = 0; i < spks.length; i++) {
                this.pukesLen--;
                this.manage.deskPukes.push(spks[i]);
                spks[i].status = false;
            }
        }
        this.manage.renderPukes();
        this.manage.renderCurDiscard();
        if(this.isCompute||gz) {
            this.manage.nextPlayer();
        }
    }
    else{
        alert("没轮到你出牌！");
    }

　　4.出牌规则的验证，是很多函数组合起来，然后循环调用，如果遇到返回ture的即为出牌符合规则：

　　

//以下为出牌规则
var rules={
    _rules:[
        new danzRule(),
        new duiRule(),
        new sandRule(),
        new zandRule(),
        new shunzRule(),
        new liandRule()
    ],
    valids:function(_pukes,_curPukes){
        for(var i=0;i<this._rules.length;i++){
            if(this._rules[i].valid(_pukes,_curPukes)){
                return true;
            }
        }
        return false;
    }
};

function danzRule(){
    //单张规则
}
danzRule.prototype.valid=function(_pukes,_curPukes){
    //校验
    var pukes=_pukes;//玩家的牌
    var curPukes=_curPukes;//左面的牌
    if(pukes&&pukes.length==1){
        //比较牌面值
        if(!curPukes||!curPukes.length){
            return true;
        }
        if(curPukes[0].dians==2&&pukes[0].dians<15){
            //2特殊处理
            return false;
        }
        if(pukes[0].dians==2&&curPukes[0].dians<15){
            //2特殊处理
            return true;
        }
        return pukes[0].dians>curPukes[0].dians;
    }
    return false;
}

function duiRule(_pukes,_curPukes){
    //两张规则

}
duiRule.prototype.valid=function(_pukes,_curPukes){
    //校验
    var pukes=_pukes;//玩家的牌
    var curPukes=_curPukes;//左面的牌
    if(pukes&&pukes.length==2){
        //比较牌面值
        if(pukes[0].dians>14&&pukes[1].dians>14){
            return true;
        }
        if(pukes[0].dians!=pukes[1].dians){
            return false;
        }
        if(!curPukes||!curPukes.length){
            return true;
        }else {
            if(curPukes.length!=2){
                return false;
            }
            if (curPukes[0].dians > 14 && curPukes[1].dians > 14) {
                return false;
            }
            if (curPukes[0].dians != curPukes[1].dians) {
                return false;
            }
            if (curPukes[0].dians == 2) {
                return false;
            }
        }
        if(pukes[0].dians==2){
            return true;
        }
        return pukes[0].dians>curPukes[0].dians;
    }
    return false;
}

function sandRule(){
    //三带
}
sandRule.prototype.valid=function(_pukes,_curPukes){
    //校验


    var pukes=_pukes;//玩家的牌
    var curPukes=_curPukes;//左面的牌
    if(pukes&&(pukes.length>=3)){

　　以上4步，是我认为的主要的4个函数，其他的函数，如初始化，事件注册等，在源码已有注释，写的不好勿喷。
