为什么80%的码农都做不了架构师？>>>

/**
 * Heartbeat
 */
$.jheartbeat = {
    options: {delay: 10000},
	beatfunction:  function(){},
	timeoutobj:  {id: -1},

    set: function(options, onbeatfunction) {
		if (this.timeoutobj.id > -1) {
			clearTimeout(this.timeoutobj);
		}
        if (options) {
            $.extend(this.options, options);
        }
        if (onbeatfunction) {
            this.beatfunction = onbeatfunction;
        }

		this.timeoutobj.id = setTimeout("$.jheartbeat.beat();", this.options.delay);
    },

    beat: function() {
		this.timeoutobj.id = setTimeout("$.jheartbeat.beat();", this.options.delay);
        this.beatfunction();
    }
};
