使用vue写一个日历界面。要求：1.显示为周视图；2.可在日历中创建行程，并且若某天中某个时间段有行程安排的话相应日历时间段部分用颜色标注；3.创建行程只能在当前时间之后的时间并且未有行程安排的时间段内创建。请给出HTML，css，JS，vue的完整代码

非常感谢您的提问，这是一个比较复杂的问题，需要一定的时间和技术含量来完成。下面是一个简单的示例，其中包含HTML，CSS，JS和Vue的完整代码，仅供参考。

HTML代码：

<div id="app">
  <h1>日历</h1>
  <table>
    <thead>
      <tr>
        <th></th>
        <th v-for="day in days">{{ day }}</th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="time in times">
        <td>{{ time }}</td>
        <td v-for="day in days" :class="{ 'has-event': hasEvent(day, time) }" @click="showModal(day, time)">
          <div v-if="hasEvent(day, time)" class="event"></div>
        </td>
      </tr>
    </tbody>
  </table>
  <div v-if="showModalFlag" class="modal">
    <div class="modal-content">
      <h2>{{ selectedDay }} {{ selectedTime }}</h2>
      <form @submit.prevent="addEvent">
        <label>名称:</label>
        <input type="text" v-model="eventName" required>
        <label>时间:</label>
        <input type="time" v-model="eventTime" :min="selectedTime" required>
        <button type="submit">创建</button>
      </form>
      <button class="close-btn" @click="closeModal">关闭</button>
    </div>
  </div>
</div>

CSS代码：

table {
  border-collapse: collapse;
  width: 100%;
}

th,
td {
  border: 1px solid black;
  padding: 10px;
  text-align: center;
}

th:first-child,
td:first-child {
  width: 100px;
}

.has-event {
  background-color: #d9d9d9;
  cursor: pointer;
}

.event {
  width: 10px;
  height: 10px;
  margin: 0 auto;
  background-color: #000;
  border-radius: 50%;
}

.modal {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  display: flex;
  justify-content: center;
  align-items: center;
}

.modal-content {
  background-color: #fff;
  padding: 20px;
  border-radius: 5px;
  width: 50%;
}

.close-btn {
  margin-top: 20px;
}

JS代码：

new Vue({
  el: '#app',
  data: {
    days: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'],
    times: ['08:00', '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00'],
    events: {},
    showModalFlag: false,
    selectedDay: '',
    selectedTime: '',
    eventName: '',
    eventTime: ''
  },
  methods: {
    hasEvent(day, time) {
      return this.events[day] && this.events[day].includes(time);
    },
    showModal(day, time) {
      const selectedDay = day;
      const selectedTime = time;
      this.selectedDay = selectedDay;
      this.selectedTime = selectedTime;
      this.showModalFlag = true;
    },
    closeModal() {
      this.showModalFlag = false;
      this.eventName = '';
      this.eventTime = '';
    },
    addEvent() {
      const { selectedDay, eventName, eventTime } = this;
      if (!this.events[selectedDay]) {
        this.events[selectedDay] = [];
      }
      this.events[selectedDay].push(eventTime);
      this.closeModal();
    }
  }
});

这个示例非常简单，仅包含周视图和创建行程的基本功能。您可以根据您的需求进行修改和扩展。
