关于Javascrit日历上显示价格取值的问题

Question

我想在这个Demo:
http://www.crazyjs.org/demo/calendar/

在这个showFu':function回调函数里，根据传进来的日期，进行比对，获取该日期的价格，比如传进来的是2014-12-9日，那么就到json数据里来找这个价格信息，
我尝试写了一些getprice的方法，执行效率都太低了，，有哪位大侠帮帮忙，帮我根据这个Json写个getprice的方法，展现到日历上
附json数据
[ { "adate":"2014/12/3","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"1","lineid":"843","beforeDay":"5","week":"星期三"}, { "adate":"2014/12/4","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"2","lineid":"843","beforeDay":"5","week":"星期四"}, { "adate":"2014/12/5","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"3","lineid":"843","beforeDay":"5","week":"星期五"}, { "adate":"2014/12/6","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"4","lineid":"843","beforeDay":"5","week":"星期六"}, { "adate":"2014/12/7","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"7","lineid":"843","beforeDay":"5","week":"星期日"}, { "adate":"2014/12/7","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"5","lineid":"843","beforeDay":"5","week":"星期日"}, { "adate":"2014/12/11","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"8","lineid":"843","beforeDay":"5","week":"星期四"}, { "adate":"2014/12/19","ss":"0","price":"1850","eprice":"1750","childpirce":"1950","id":"6","lineid":"843","beforeDay":"5","week":"星期五"}]
