I use
var time = new Date("17 五月 2017 14:01:59")
Conversion error, but use
var time = new Date("2017-05-17 14:01:59")
Conversion successful. If I have to convert using the following date format:
17 五月 2017 14:01:59
How to deal with it?
闭关修行中......
const dateStr = '17 五月 2017 14:01:59' function convert2ISO8061 (dateStr) { const units = dateStr.split(' ') return units[2] + '-' + convertMonth(units[1]) + '-' + units[0] + 'T' + units[3] + 'Z' } function convertMonth (mStr) { const months = ['一月', '二月', '三月', '四月', '五月', '六月', '七月', '八月', '九月', '十月', '十一月', '十二月'] const month = months.indexOf(mStr) + 1 if (month < 10) { return '0' + month } return parseInt(month) } console.log(Date.parse(convert2ISO8061(dateStr)))
First convert "17 五月 2017 14:01:59" 使用 split(' ') into an array arr.
"17 五月 2017 14:01:59"
split(' ')
Write another function to convert Chinese characters 五月 into numeric form, and then use the array arr to iterate and recombine it into the date format you need.
五月
var time = new Date("17 May 2017 14:01:59"); It's ok; so you just need to replace the Chinese month with the English abbreviation and it's ok.
You need to re-do the May one yourself and then splice it
I misunderstood the meaning just now, but it can be written like this according to the above idea
function converDate(date){ var arr=date.split(' '); var ENdate=['Jan', 'Feb', 'Mar', 'April', 'May', 'Jan', 'July', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']; var CNdate=['一月', '二月', '三月', '四月', '五月', '六月', '七月', '八月', '九月', '十月', '十一月', '十二月']; var idx=CNdate.indexOf(arr[1]); arr[1]=ENdate[idx]; return new Date(arr.join(' ')); } converDate('17 五月 2017 14:01:59');
