JS模式---命令模式

var opendoor = {
            execute: function () {
                console.log("开门");
            }
        };
        var closedoor = {
            execute: function () {
                console.log("关门");
            }
        };
        var lighton = {
            execute: function () {
                console.log("开灯");
            }
        };

        var cmd = function () {
            return {
                cmdList: [],
                add:function(c){
                    this.cmdList.push(c);
                },
                execute: function () {
                    for (var i = 0, c; c = this.cmdList[i++];) {
                        c.execute();
                    }
                }
            }
        };
        var command = cmd();
        command.add(opendoor);
        command.add(closedoor);
        command.add(lighton);
        command.execute();

通过执行宏命令方式，可以一次执行一批命令。
