Mastering VueJS 3 Datepicker: Adding an Extra Class on Highlighted Dates

Are you tired of struggling with customizing the VueJS 3 Datepicker? Do you want to add a personal touch to your datepicker by adding an extra class on highlighted dates? Look no further! In this article, we’ll take you on a step-by-step journey to achieve this feat.

Understanding the Problem

By default, the VueJS 3 Datepicker uses the `highlighted` prop to mark specific dates as highlighted. However, this prop only adds a default class `highlighted` to the highlighted dates, which may not be enough for your customization needs. This is where adding an extra class comes into play.

The Challenge

The main challenge lies in overrides the default behavior of the `highlighted` prop and adding an extra class to the highlighted dates. This requires a deep understanding of how the VueJS 3 Datepicker works and how to tap into its internal mechanisms.

Solution Overview

To add an extra class on highlighted dates, we’ll use a combination of techniques:

1. Using a custom render function to override the default rendering of the datepicker
2. Creating a custom class to style the highlighted dates
3. Hooking into the `highlighted` prop to add the extra class

Step 1: Create a Custom Render Function

To override the default rendering of the datepicker, we need to create a custom render function. This function will allow us to access the internal DOM elements of the datepicker and add our extra class.

<template>
  <VuejsDatepicker
    :render-day-cell="(dayCellData) => renderDayCell(dayCellData)"
  />
</template>

<script>
export default {
  methods: {
    renderDayCell(dayCellData) {
      // we'll add our custom logic here
    }
  }
}
</script>

Step 2: Create a Custom Class

Next, we need to create a custom class to style the highlighted dates. Add the following CSS code to your stylesheet:

.extra-highlight {
  background-color: #ffe; /* or any other style you prefer */
}

Step 3: Hook into the Highlighted Prop

Now, we’ll hook into the `highlighted` prop to add our extra class. Update the `renderDayCell` function as follows:

<script>
export default {
  methods: {
    renderDayCell(dayCellData) {
      if (dayCellData.highlighted) {
        dayCellData.attributes.class += ' extra-highlight';
      }
      return dayCellData;
    }
  }
}
</script>

In this code, we’re checking if the `highlighted` prop is true for the current date. If it is, we’re adding our extra class `extra-highlight` to the date cell’s class attribute.

Putting it All Together

Here’s the complete code:

<template>
  <VuejsDatepicker
    :render-day-cell="(dayCellData) => renderDayCell(dayCellData)"
  />
</template>

<script>
export default {
  methods: {
    renderDayCell(dayCellData) {
      if (dayCellData.highlighted) {
        dayCellData.attributes.class += ' extra-highlight';
      }
      return dayCellData;
    }
  }
}
</script>

<style>
.extra-highlight {
  background-color: #ffe; /* or any other style you prefer */
}
</style>

Result

With this code, you should now see the extra class `extra-highlight` added to the highlighted dates. You can customize the styles as per your needs.
