How to use Vue to implement calendar selection effects

In modern web application development, calendar selection is a common functional requirement. Through calendar selection, users can easily select dates to query events or make appointments. In this article, we will introduce how to use the Vue framework to implement a simple and practical calendar selection effect to meet the needs of daily development.

Build a Vue project
First, we need to build a project based on the Vue framework. You can use Vue CLI to quickly build a project skeleton, or manually build a simple project structure.
Installing dependencies
In the root directory of the project, open the terminal and execute the following command to install the necessary dependencies:

npm install vue vue-router vuex

Create the calendar component
In In the Vue project, we need to create a calendar component to display the calendar interface. Create a Calendar.vue file in the src directory and add the following code:

<template>
  <div class="calendar">
    <h2>{{ year }}年{{ month }}月</h2>
    <table>
      <thead>
        <tr>
          <th v-for="week in weeks" :key="week">{{ week }}</th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="week in calendar" :key="week">
          <td v-for="day in week" :key="day" @click="selectDate(day)">{{ day }}</td>
        </tr>
      </tbody>
    </table>
  </div>
</template>

<script>
export default {
  data() {
    return {
      now: new Date(),
      year: 0,
      month: 0,
      weeks: ['日', '一', '二', '三', '四', '五', '六'],
      calendar: []
    };
  },
  mounted() {
    this.updateCalendar();
  },
  methods: {
    updateCalendar() {
      const firstDay = new Date(this.now.getFullYear(), this.now.getMonth(), 1);
      const lastDay = new Date(this.now.getFullYear(), this.now.getMonth() + 1, 0);
      this.year = this.now.getFullYear();
      this.month = this.now.getMonth() + 1;
      
      const gap = firstDay.getDay();
      const days = lastDay.getDate();
      let calendar = [];
      let week = [];

      for (let i = 0; i < gap; i++) {
        week.push('');
      }
      for (let i = 1; i <= days; i++) {
        week.push(i);
        if ((gap + i) % 7 === 0) {
          calendar.push(week);
          week = [];
        }
      }
      if (week.length) {
        calendar.push(week);
      }

      this.calendar = calendar;
    },
    selectDate(day) {
      // 处理日期选择逻辑
    }
  }
};
</script>

<style scoped>
.calendar {
  display: inline-block;
  padding: 10px;
  border: 1px solid #ccc;
}

.calendar h2 {
  margin: 0 0 10px;
  text-align: center;
}

.calendar table {
  width: 100%;
  table-layout: fixed;
}

.calendar th,
.calendar td {
  padding: 5px;
  text-align: center;
}

.calendar td {
  cursor: pointer;
}

.calendar .selected {
  background-color: #ccc;
}
</style>

Using the calendar component in the project
Introduce the Calendar component where calendar selection effects are needed. , and use it:

<template>
  <div>
    <Calendar></Calendar>
  </div>
</template>

<script>
import Calendar from '@/components/Calendar';

export default {
  components: {
    Calendar
  }
};
</script>

Through the above steps, we have implemented a basic calendar selection component. Users can click on a date to select a date, and the selected date will have a special style.

You can add more functions to the calendar component according to actual needs, such as limiting the optional date range, adding event markers, etc. Through the powerful features and component-based development of the Vue framework, we can efficiently implement calendar selection effects and improve user experience.
