  你可以使用 [A-Z]{2}\d{3,5}[A-Z, a-z]{1}(\D*[0-9]{1,2}\D*[0-9]{4}) ，

  这将使您想要的输出与捕获组 (\D*[0-9]{1,2}\D*[0-9]{4}) 匹配 . 它将匹配任意数量的非数字字符（日期），1-2个数字（数字的日期），任何非数字以匹配月份和4个数字以匹配年份 .

  感谢您的所有回复 .

  在上述所有回复的帮助下，我 Build 了一个正则表达式，以获得如下的出发日期

  ((?<=[A-Z]{2}\d{3,5}[A-Z, a-z]{1})(\D*[0-9]{1,2}\D*[0-9]{4}))

  它完美地工作 .

  感谢帮助！！

  这是正则表达式 /.+((?:Sun|Mon|Tue|Wed|Thu|Fri|Sat).+)/

  • 我使用非捕获括号列出一周中每天的3个首字母的所有可能性

  • 捕获从非捕获括号中找到的任何一天的任何字符

  var chains = [
    "AA78654UThursday 11 October 2018",
    "SI9089UFriday 11 October 2018",
    "WW0461XMonday 26 October 2018",
    "GF00356ZSunday 26 October 2018"
  ];
  var pattern = /.+((?:Sun|Mon|Tue|Wed|Thu|Fri|Sat).+)/
  var dates = [];
  chains.forEach(function(chain) {
    $matches = chain.match(pattern);
    dates.push($matches[1]);
  });
  
  console.log(dates);

  尝试以下内容

  window.onload = function()
  {
  
  var source = 'AA78654UThursday 11 October 2018'
  
  var regex = /[A-Z]{2}\d{3,5}\w{1}/g
  
  var matches = regex.exec(source)
  
  if (matches)
  {
    source = source.replace(matches, "");
    
    console.log(source);
  }
  
  }

  您可以使用 for ... in 循环和String.replace()删除初始信息 .

  let dateArray = [
    'AA78654UThursday 11 October 2018',
    'SI9089UFriday 11 October 2018',
    'WW0461XMonday 26 October 2018',
    'GF00356ZSunday 26 October 2018'
  ];
  
  const regex = /[A-Z]{2}\d{3,5}\S/g;
  
  for (let i in dateArray) dateArray[i] = dateArray[i].replace(regex, '');
  
  console.log(dateArray);

  您可以使用的正则表达式是 /(Monday|Tuesday|Wednesday|Thursday|Friday|Saturday|Sunday)+.+$# ，但最后一部分不包含捕获组 . 如果您还想捕获此部分，则应将整个正则表达式括在括号中 .

  出发日期：

  (Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday)\s([123][0-9])\s(January|February|March|April|May|June|July|August|September|October|November|December)\s(\d{4})
  

  说明

  (Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday)  // Match Day
  \s  // Blank Space after day
  ([123][0-9])  // Match date
  \s  // Blank Space after date
  (January|February|March|April|May|June|July|August|September|October|November|December)  // Match month
  \s  // Blank space after month
  (\d{4})  // Match Year
  

  匹配整件事：

  ([A-Z]{2}\d{3,5})([A-Z])((Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday)\s([123][0-9])\s(January|February|March|April|May|June|July|August|September|October|November|December)\s(\d{4}))
