javascript - javascript - 字符串到日期 - php iso 字符串格式

Question

我的日期格式为：
2010-11-30T08:32:22+0000
2010-11-27T20:59:17+0000
来自提要，以字符串格式转换为 javascript，现在我想将其转换为 Date 对象。我怎样才能在javascript中做到这一点？

此代码适用于 IE/Firefox/Chrome：

new Date("2010-11-30T08:32:22+0000".replace(/-/g,'/').replace(/T/,' ').replace(/\+/,' +'))

它更改2010-11-30T08:32:22+0000为2010/11/30 08:32:22 +0000然后从固定字符串创建 Date 对象。

我不确定你是否应该使用它，它看起来真的很脏。

也许这是一个矫枉过正，但试试Datejs

这个配方不考虑时区。您需要对其进行更多修改才能使其与 TZ 一起使用。如果您确定时区始终为+0000，则此代码将起作用：

var s = "2010-11-30T08:32:22+0000";
// Replace non-digit characters with a space
s = s.replace(/\D/g," ");
// Split the string on space
var date_parts = s.split(" ");

// subtract 1 from month to use in Date constructor
var yyyy = date_parts[0],
    mm = date_parts[1] - 1,
    dd = date_parts[2],
    hh = date_parts[3],
    mi = date_parts[4],
    ss = date_parts[5];

// Now, the date_parts has year, month, date and so on
var dt = new Date(yyyy, mm, dd, hh, mi, ss);

这是我从JavaScript Cookbook中学到的食谱的稍微冗长的版本

新浏览器版本支持 new Date("2010-11-30T08:32:22+0000") (Chrome, FF4, IE9)，但旧浏览器不支持。

如果时区没有意义（在它始终为零（您的情况）或省略的情况下），您可以使用这个：

Date.fromISOString = (function(){
  function fastDateParse(y, m, d, h, i, s, ms){
    return new Date(y, m - 1, d, h || 0, i || 0, s || 0, ms || 0);
  }

  // result function
  return function(isoDateString){
    return fastDateParse.apply(null, isoDateString.split(/\D/));
  }
})();

如果您需要使用时区解析，请使用：

Date.fromISOString = (function(){
  var tzoffset = (new Date).getTimezoneOffset();
  function fastDateParse(y, m, d, h, i, s, ms){ // this -> tz
    return new Date(y, m - 1, d, h || 0, +(i || 0) - this, s || 0, ms || 0);
  }

  // result function
  return function(isoDateString){
    var tz = isoDateString.substr(10).match(/([\-\+])(\d{1,2}):?(\d{1,2})?/) || 0;
    if (tz)
      tz = tzoffset + (tz[1] == '-' ? -1 : 1) * (tz[3] != null ? +tz[2] * 60 + (+tz[3]) : +tz[2]);
    return fastDateParse.apply(tz || 0, isoDateString.split(/\D/));
  }
})();

日期的正确形式：

Date.fromISOString('2011-06-01');
Date.fromISOString('2011-06-01T00:00:00');
Date.fromISOString('2011-06-01T00:00:00Z');
Date.fromISOString('2011-06-01T00:00:00+30');
Date.fromISOString('2011-06-01T00:00:00-30');
Date.fromISOString('2011-06-01T00:00:00+0530');
Date.fromISOString('2011-06-01T00:00:00-0530');
Date.fromISOString('2011-06-01T00:00:00+05:30');
Date.fromISOString('2011-06-01T00:00:00-05:30');

// Your example valid as well.
Date.fromISOString("2010-11-30T08:32:22+0000")

var someDate = new Date("2010-11-30T08:32:22+0000");

我不认为它可以更简单。

这可能是一个选择

> s = '2010-11-30T08:32:22+0000'.split(/\D/);
> new Date(Date.UTC(s[0], --s[1]||'', s[2]||'', s[3]||'', s[4]||'', s[5]||'', s[6]||''))

我发现像 Date.fromISOString('2011-06-01T00:00:00Z') 这样的情况会创建被时区偏移的日期，因此只有在您的计算机处于 GMT 时才能正常工作。这是我为解决此问题所做的更改。

要从任何给定的 ISO 字符串中获取正确的日期，即使给定的条目是 GMT，您也需要调整本地时区。

这是您可以保存为 .html 文件并在您的计算机上测试的工作示例：
