如果日期是今天的日期显示"today"，或者"yesterday"

Question

在我的 Shopify 博客中，我可以通过以下代码显示发布文章的日期：

{{ article.created_at | date: "%A, %-d. %B" }}

显示如下：1 月 22 日，星期五。 See date desc from Shopify here.

是否可以制作一个脚本来检查日期是否为今天，然后显示文本 "today" insted shopify 日期脚本？还有 "yesterday"?

Answer 1

您可以使用 Control Flow Tags 来实现。

  {%if {{article.created_at|date: "%Y %b %d"}}== {{ 'now' | date: "%Y %b %d" }} %}
       Today
    {% else %}
    Yesterday
      {% endif %}

Answer 2

Shopify 可能有一个内置的解决方案，但如果没有，运行页面加载后的这个脚本应该会给你一个方法来做你想做的事。

不过请注意，要计算的日期。还要有年份，不然会出错

请求不显示年份后更新

要显示没有年份的日期，您可以这样做，您可以按照自己喜欢的方式设置可见日期的格式，因为它使用 data-date 计算值。

一个积极的副作用是，如果您需要日期，它仍然会存在于 data-date 属性中。

<span class="date" data-date='{{ article.published_at | date: "%F" }}'>{{ article.created_at | date: "%A, %-d. %B" }}</span>

更新示例

function makeYMD(d) {
  return d.getFullYear() + "-" + (d.getMonth() + 1) + "-" + d.getDate();
}
function getYesterday(d) {
  return new Date(d.setDate(d.getDate() - 1));
}

var span = document.querySelector('span.date');
var spandate = new Date(span.getAttribute("data-date"));
var today = new Date();
var yesterday = getYesterday(new Date());

spandate = makeYMD(spandate);
today = makeYMD(today);
yesterday = makeYMD(yesterday);


if(today == spandate) {
   span.textContent = "Today";
} else if(yesterday == spandate) {
   span.textContent = "Yesterday";
}

<span class="date" data-date='2016-01-31'>Monday, 31. January</span>

Answer 3

在这里测试https://jsfiddle.net/027jch3z/

var now = new Date;
function today( created_at_day,created_at_month,created_at_year, now ){
 return created_at_day== now.getUTCDate() &&
         created_at_month == (now.getUTCMonth()+1) &&
         created_at_year == now.getUTCFullYear();
}

// for yesterday, do some calculation here,
var yest = new Date(now);
yest = new Date(yest.setDate(d.getDate() -1));

function yesterday( created_at_day,created_at_month,created_at_year, yest )
{
  return created_at_day == yest.getUTCDate() &&
         created_at_month == (yest.getUTCMonth() +1) &&
         created_at_year == yest.getUTCFullYear();
}


//test calls
alert("Today: "+today(1,2,2016,now));
alert("Yesterday: "+yesterday(31,1,2016,yest));

Answer 4

这是一个，使用 toLocaleDateString():

function renderDate(date) {
  const today = new Date
  const yesterday = new Date; yesterday.setDate(today.getDate() - 1)
  if(date.toLocaleDateString() == today.toLocaleDateString()){
    return 'Today'
  }else if (date.toLocaleDateString() == yesterday.toLocaleDateString()) {
    return 'Yesterday'
  }
  return date.toLocaleDateString('en-US', {
    day : 'numeric',
    month : 'long'
  })
}
//Test:
renderDate(new Date('2016-11-11'))
"Today"
renderDate(new Date('2016-11-10'))
"Yesterday"
renderDate(new Date('2016-11-0'))
"Invalid Date"
renderDate(new Date('2016-11-5'))
"November 5"

Answer 5

使用 AngularJS 过滤器即可。请在此处查看示例：

演示：https://www.screencast.com/t/rh609WQI6

代码：https://codepen.io/skounis/pen/PKPKGw

.filter('tyday', function($filter) {
  return function(input, pattern) {
    if (!pattern) {
                pattern = 'EEEE, MMM d';
            }
            var today = $filter('date')(new Date(), pattern);

            var yday = new Date();
            yday.setDate(yday.getDate() - 1);
            var yesterday = $filter('date')(yday, pattern);

            if (input === today) {
                return 'Today';
            }

            if (input === yesterday) {
                return 'Yesterday';
            }

            return input;
  };
});

如果日期是今天的日期显示"today"，或者"yesterday"

If date is todays date display "today", or "yesterday"
