Using Vue's V-IF directive to compare dates

On my website, I have an object that contains a field named available_at with the date in the format of 2019-08-08

I have a working HTML table utilizing Vue bindings but I am unsure how to compare the timestamp above using the built-in Date.now() method

<tr :class="[dateEvent.priority + '-priority', 'status-' + dateEvent.status]">
  <td v-if="dateEvent.task_typet_id === '2' && dateEvent.name === 'Task Title' && dateEvent.available_at === Date.now()">{{ dateEvent.task_identifier }}</td>
</tr>

What would be the correct way to check this field against the current date?

Answer №1

These are a few key points to consider:

  • When comparing JavaScript Date objects, keep in mind that the equality comparison === requires an exact match down to the millisecond.

  • If you need to convert a string to a Date object, you can do so by using the constructor method, for example:

     new Date("2019-08-08")

This will generate a date representing midnight on August 8th.

  • Ensure that you handle time zones properly - is the provided date in local time or UTC?

Consider utilizing a computed property to streamline your template and explore the available methods for manipulating Date objects to tailor your comparisons to suit your application's requirements.

Answer №2

To determine if two dates fall on the same day, you can use the following code snippet:

function checkSameDay(date1, date2){
  return date1.getFullYear() === date2.getFullYear() &&
    date1.getMonth() === date2.getMonth() &&
    date1.getDay() === date2.getDay()
}

console.log(checkSameDay(new Date(), new Date(dateEvent.available_at))

If you prefer, you can also utilize tools like moment to manage various date formats.

Answer №3

If you want to compare dates, the moment library is a convenient tool:

moment().isSame(dateEvent.available_at, 'day');

Using this code snippet will compare the current date with the date stored in dateEvent.available_at on a daily basis.
