<div data-v-78561074="" class="btn flex-center"><!----> <span data-v-78561074="" class="applyBtn"> 去练习 </span></div> selenium如何定位这个元素

可以使用 Selenium 的 find_element_by_css_selector 或 find_element_by_xpath 方法进行定位该元素。

使用 CSS 选择器定位：

element = driver.find_element_by_css_selector('div.btn > span.applyBtn')

使用 XPath 定位：

element = driver.find_element_by_xpath('//div[@class="btn flex-center"]/span[@class="applyBtn"]')

其中 driver 是一个已经打开的 WebDriver 对象。

用uni-app 写一个功能完整的校历

好的，以下是一个功能完整的uni-app校历的代码示例，包括日历视图、事件添加、查看和编辑等功能，你可以根据自己的需求进行修改和优化：

1. 创建uni-app项目，选择vue-cli模板和uni-app框架。

2. 在pages文件夹下创建calender.vue文件，编写校历页面的HTML结构和样式，例如：

<template>
  <div class="calender">
    <div class="calender-header">
      <img src="../static/logo.png" alt="logo">
      <h1>{{ title }}</h1>
      <button @click="addEvent">添加事件</button>
    </div>
    <div class="calender-view">
      <div class="calender-view-header">
        <button @click="changeMonth(-1)">上个月</button>
        <span>{{ currentYear }}年{{ currentMonth }}月</span>
        <button @click="changeMonth(1)">下个月</button>
      </div>
      <div class="calender-view-body">
        <div v-for="(week, index) in weeks" :key="index" class="calender-view-week">
          <div v-for="(day, key) in week" :key="key" class="calender-view-day" :class="{ 'current-month': day.month === currentMonth, 'today': day.date === today, 'selected': day.date === selectedDate }" @click="selectDate(day.date)">
            <span class="day">{{ day.date }}</span>
            <ul class="events">
              <li v-for="event in day.events" :key="event.id">{{ event.title }}</li>
            </ul>
          </div>
        </div>
      </div>
    </div>
    <div class="event-popup" :class="{ 'show': showPopup }">

3. 在script标签中，定义页面的数据和方法，例如：

<script>
  export default {
    data() {
      return {
        title: '2021年校历',
        currentYear: new Date().getFullYear(),
        currentMonth: new Date().getMonth() + 1,
        today: new Date().getDate(),
        selectedDate: 0,
        weeks: [],
        events: [
          {
            id: 1,
            date: '2021-01-01',
            title: '元旦节',
            content: '2021年元旦节'
          },
          {
            id: 2,
            date: '2021-02-12',
            title: '春节',
            content: '2021年春节'
          },
          // 其他事件
        ],
        popupTitle: '',
        popupDate: '',
        popupEvent: {
          id: 0,
          date: '',
          title: '',
          content: ''
        },
        showPopup: false
      }
    },
    mounted() {
      this.generateWeeks()
    },
    methods: {
      generateWeeks() {
        let weeks = []
        let daysOfMonth = new Date(this.currentYear, this.currentMonth, 0).getDate()
        let startDay = new Date(this.currentYear, this.currentMonth - 1, 1).getDay()
        let endDay = new Date(this.currentYear, this.currentMonth - 1, daysOfMonth).getDay()
        let days = []
        for (let i = 1; i <= daysOfMonth; i++) {
          days.push({
            date: i,
            month: this.currentMonth,
            events: this.getEventsByDate(`${this.currentYear}-${this.currentMonth}-${i}`)
          })
        }
        for (let i = 0; i < startDay; i++) {
          days.unshift({})
        }
        for (let i = 0; i < 6 - endDay; i++) {
          days.push({})
        }
        for (let i = 0; i < 35; i += 7) {
          weeks.push(days.slice(i, i + 7))
        }
        this.weeks = weeks
      },
      changeMonth(offset) {
        this.currentMonth += offset
        if (this.currentMonth > 12) {
          this.currentMonth = 1
          this.currentYear++
        } else if (this.currentMonth < 1) {
          this.currentMonth = 12
          this.currentYear--
        }
        this.generateWeeks()
      },
      selectDate(date) {
        this.selectedDate = date
      },
      addEvent() {
        this.popupTitle = '添加事件'
        this.popupDate = `${this.currentYear}-${this.currentMonth}-${this.selectedDate}`
        this.popupEvent = {
          id: 0,
          date: '',
          title: '',
          content: ''
        }
        this.showPopup = true
      },
      editEvent(event) {
        this.popupTitle = '编辑事件'
        this.popupDate = event.date
        this.popupEvent = Object.assign({}, event)
        this.showPopup = true
      },
      saveEvent() {
        let event = Object.assign({}, this.popupEvent)
        if (event.id === 0) {
          event.id = this.events.length + 1
          this.events.push(event)
        } else {
          let index = this.events.findIndex(item => item.id === event.id)
          this.events.splice(index, 1, event)
        }
        this.showPopup = false
        this.generateWeeks()
      },
      deleteEvent(event) {
        let index = this.events.findIndex(item => item.id === event.id)
        this.events.splice(index, 1)
        this.generateWeeks()
      },
      getEventsByDate(date) {
        let events = this.events.filter(event => event.date === date)
        return events
      },
      closePopup() {
        this.showPopup = false
      }
    },
    computed: {
      popupDateStr() {
        let date = new Date(this.popupDate)
        let year = date.getFullYear()
        let month = date.getMonth() + 1
        let day = date.getDate()
        return `${year}-${month.toString().padStart(2, '0')}-${day.toString().padStart(2, '0')}`
      }
    }
  }
</script>

4. 在页面中，使用方法和数据渲染日历视图、事件列表和事件弹出框，例如：

<div class="calender-view">
  <div class="calender-view-header">
    <button @click="changeMonth(-1)">上个月</button>
    <span>{{ currentYear }}年{{ currentMonth }}月</span>
    <button @click="changeMonth(1)">下个月</button>
  </div>
  <div class="calender-view-body">
    <div v-for="(week, index) in weeks" :key="index" class="calender-view-week">
      <div v-for="(day, key) in week" :key="key" class="calender-view-day" :class="{ 'current-month': day.month === currentMonth, 'today': day.date === today, 'selected': day.date === selectedDate }" @click="selectDate(day.date)">
        <span class="day">{{ day.date }}</span>
        <ul class="events">
          <li v-for="event in day.events" :key="event.id" @click="editEvent(event)">{{ event.title }}</li>
        </ul>
      </div>
    </div>
  </div>
</div
