Apr 04, 2025 pm 05:00 PM Vue Material Year Calendar plug-in: Solutions for failed calendar selection status update after activeDates.push
When using the vue-material-year-calendar
plugin, developers often encounter a problem: after adding dates to activeDates
arrays, the calendar interface cannot update the selected status. This article analyzes and solves this problem.
Problem: Following the official documentation example, after clicking on the date, add the date information to the activeDates
array, but the calendar interface does not update the selected status, although the console shows that activeDates
array already contains the date.
The root cause: vue-material-year-calendar
plug-in is related to the Vue version and the binding method of activeDates
attributes. Vue 2 and Vue 3 have different solutions.
Vue 2 Solution:
The combination of v-model
and :activeDates.sync
may conflict with the plugin internal mechanism. Solution: Remove the .sync
modifier, use the :activeDates
binding directly, and manually update the activeDates
array in the event handling function, and force the view to update. Modified code example:
<yearcalendar :activeclass="activeclass" :activedates="activedates" prefixclass="your_customized_wrapper_class" v-model="year"></yearcalendar>
Vue 3 Solution:
Vue 3 recommends using responsive APIs such as ref
and reactive
. You need to add a selected
attribute to indicate the selected status in each date object and wrap the activeDates
array with ref
. Example:
const activeDates = ref([ { date: '2024-02-13', selected: true, className: '' }, { date: '2024-02-14', className: 'red' }, { date: '2024-02-15', className: 'blue' }, { date: '2024-02-16', className: 'your_customized_classname' } ]);
Vue 3 can correctly track activeDates
array changes and update views. The corresponding date click event handling function also needs to be modified to update the selected
attribute.
Summary: Selecting the appropriate solution according to the Vue version can solve the problem of failed calendar selection status update after activeDates.push
. The key is to make sure that changes in activeDates
array trigger view updates correctly.
