javascript - js, échec de la conversion de la date

Question

J'utilise

var time = new Date("17 五月 2017 14:01:59")

Erreur de conversion, mais utilisation de

var time = new Date("2017-05-17 14:01:59")

Conversion réussie.
Si je dois convertir en utilisant le format de date suivant :

17 五月 2017 14:01:59  

Comment y faire face ?

Answer 1

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)))

Answer 2

Convertissez d'abord "17 mai 2017 14:01:59" en un tableau arr en utilisant split(' '). "17 五月 2017 14:01:59" 使用 split(' ') 转换为数组 arr。

再写一个函数将汉字 五月

Écrivez une autre fonction pour convertir le caractère chinois May en forme numérique, puis utilisez le tableau arr pour le parcourir et le recombiner dans le format de date dont vous avez besoin. 🎜

Answer 3

var time = new Date("17 May 2017 14:01:59"); C'est ok ; il vous suffit donc de remplacer le mois chinois par l'abréviation anglaise et c'est ok.

Answer 4

Vous devez refaire celui de mai vous-même, puis l'assembler

Answer 5

J'ai mal compris le sens tout à l'heure, mais cela peut être écrit ainsi selon l'idée ci-dessus

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');
