我想使用https://raw.github.com/currencybot/open-exchange-rates/master/latest.json提供的货币数据
作为初始测试,我创建了一个精简版作为内联对象:
var obj = [
{

"timestamp": 1339036116,
"base": "USD",
"rates": {
"EUR": 0.795767,
"GBP": 0.645895,
"JPY": 79.324997,
"USD": 1
}
}];
我想要做的就是以某种方式查询/grep/过滤json对象,例如,“EUR”作为标准,并让它返回一个名为“rate”的变量,结果为“0.795767”。
我查看了 JQuery grep 和 filter 函数,但我不知道如何仅隔离对象的“rates”部分,然后获得我想要的速率。
