大家好，javascript中有这个变量
gateco = { "thursday": [{ "open": "12:00", "close": "18:49" }], "friday": [{ "open": "12:00", "close": "18:59" }] };
如何获取utc-5时间的日期，并根据日期分别访问打开和关闭值？

你可以这样做。。。请参见此处的时区列表
const dateTimeOption = { timeZone : 'Etc/GMT+5' , hour12 : false , weekday : 'long' , hour : '2-digit' , minute : '2-digit' } , gateco = { thursday : [ { open: '12:00', close: '18:49' } ] // why is it an Array ? , friday : [ { open: '12:00', close: '18:59' } ] } let isOpenNow = false , [wDay,h,m] = new Intl.DateTimeFormat('en-US', dateTimeOption) .format(new Date()) .split(/:| /) .map(s=>Number(s)||s.toLowerCase() ) if ( gateco[wDay] ) { let hm = (h *100) +m // simplied for comparing , h_m_Open = gateco[wDay][0].open .split(':') .reduce((hm,t,i)=>hm + (!i?100:1)*Number(t) ,0) , h_m_Close = gateco[wDay][0].close .split(':') .reduce((hm,t,i)=>hm + (!i?100:1)*Number(t) ,0) isOpenNow = (h_m_Open <= hm && hm <= h_m_Close) } //console.log( wDay,h,m ) console.log( 'isOpenNow = ', isOpenNow)
