返回

{"query":{"count":1,"created":"2017-03-14T23:41:16Z","lang":"en-us","results":{"channel":{"astronomy":{"sunrise":"6:35 am","sunset":"6:35 pm"}}}}}

有解决这个问题的想法吗？我想我可以在冒号处对时间进行切片，然后将结果填充到 2 位数字，但这看起来很困惑。

Answer 1

var el = {"query":{"count":1,"created":"2017-03-14T23:49:12Z","lang":"ru-RU","results":{"channel":{"astronomy":{"sunrise":"7:5 am","sunset":"7:0 pm"}}}}};
var a = el.query.results.channel.astronomy;

for(var i in a)
{
    if (/^\d{1,2}\:\d{1}\s/.test( a[i] ))
    {
        var value = /^\d{1,2}(\:\d)\s/.exec(a[i])[1];
        a[i] = a[i].replace( value, ':0' + value.substr(1) )
    }
}

console.log(a)
