<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。

利用vue和element-ui ，实现需求弹窗右上角关闭按钮左面新增一个减号缩小按钮，把弹窗缩小到只有一个放大按钮和一个关闭按钮的div，div的功能有三个：1div可以拖拽，2放大按钮可以还原弹窗大小，关闭按钮是把弹窗关闭。请用具体代码来实现

好的，我会尽力回答您的问题。

首先，我们需要在弹窗组件的模板中添加一个新的按钮，用于缩小弹窗。同时，我们还需要为弹窗组件添加一些事件处理函数，用于拖拽和缩小弹窗。

下面是实现该需求的代码示例：

<template>
  <div class="dialog-container" :style="dialogStyle">
    <div class="header">
      <span class="title">{{ title }}</span>
      <el-button class="btn-minimize" icon="el-icon-minus" @click="minimize"></el-button>
      <el-button class="btn-close" icon="el-icon-close" @click="close"></el-button>
    </div>
    <div class="body">
      <!-- 弹窗内容 -->
    </div>
  </div>
</template>

<script>
export default {
  name: 'MyDialog',
  props: {
    title: {
      type: String,
      default: ''
    }
  },
  data() {
    return {
      dialogStyle: {
        top: '50px',
        left: '50px',
        width: '400px',
        height: '300px',
        zIndex: '1000'
      },
      isDragging: false,
      mouseX: 0,
      mouseY: 0,
      dialogWidth: 0,
      dialogHeight: 0,
      isMinimized: false,
      savedDialogStyle: null
    }
  },
  methods: {
    close() {
      // 关闭弹窗
      this.$emit('close')
    },
    minimize() {
      if (!this.isMinimized) {
        // 保存当前弹窗样式
        this.savedDialogStyle = Object.assign({}, this.dialogStyle)
        // 缩小弹窗
        this.dialogStyle.width = '100px'
        this.dialogStyle.height = '50px'
        this.isMinimized = true
      } else {
        // 还原弹窗大小
        Object.assign(this.dialogStyle, this.savedDialogStyle)
        this.isMinimized = false
      }
    },
    startDrag(e) {
      // 开始拖拽
      this.isDragging = true
      this.mouseX = e.clientX
      this.mouseY = e.clientY
      this.dialogWidth = this.$el.offsetWidth
      this.dialogHeight = this.$el.offsetHeight
    },
    onDrag(e) {
      // 拖拽中
      if (this.isDragging) {
        let dx = e.clientX - this.mouseX
        let dy = e.clientY - this.mouseY
        this.dialogStyle.left = (parseInt(this.dialogStyle.left) + dx) + 'px'
        this.dialogStyle.top = (parseInt(this.dialogStyle.top) + dy) + 'px'
      }
    },
    stopDrag() {
      // 结束拖拽
      this.isDragging = false
    }
  },
  mounted() {
    // 添加拖拽事件
    this.$el.addEventListener('mousedown', this.startDrag)
    window.addEventListener('mousemove', this.onDrag)
    window.addEventListener('mouseup', this.stopDrag)
  },
  beforeDestroy() {
    // 移除拖拽事件
    this.$el.removeEventListener('mousedown', this.startDrag)
    window.removeEventListener('mousemove', this.onDrag)
    window.removeEventListener('mouseup', this.stopDrag)
  }
}
</script>

<style>
.dialog-container {
  position: absolute;
  border: 1px solid #ccc;
  background-color: #fff;
  border-radius: 4px;
}

.header {
  height: 40px;
  padding: 8px;
  border-bottom: 1px solid #ccc;
  display: flex;
  align-items: center;
  justify-content: space-between;
}

.title {
  font-size: 16px;
  font-weight: bold;
}

.btn-minimize {
  margin-left: 8px;
}

.body {
  padding: 16px;
  height: calc(100% - 40px);
}

.btn-close {
  position: absolute;
  top: 8px;
  right: 8px;
}
</style>

在上面的代码中，我们添加了一个名为 `btn-minimize` 的缩小按钮，并为其绑定了 `minimize` 方法，用于缩小弹窗。同时，我们还为弹窗容器添加了 `isDragging`、`mouseX`、`mouseY`、`dialogWidth`、`dialogHeight`、`isMinimized` 和 `savedDialogStyle` 等多个状态，用于支持拖拽和缩小弹窗的功能。

在 `minimize` 方法中，我们通过保存当前弹窗样式的方式实现了缩小功能。具体来说，我们将当前弹窗样式保存到 `savedDialogStyle` 变量中，然后将弹窗的宽度和高度设置为固定值，以实现缩小的效果。当用户点击缩小按钮时，如果弹窗已经被缩小，则将弹窗的样式还原为之前保存的样式，以实现还原的效果。

在 `startDrag`、`onDrag` 和 `stopDrag` 方法中，我们实现了拖拽弹窗的功能。具体来说，我们在 `mounted` 钩子函数中添加了拖拽事件的监听器，当用户按下鼠标左键时，会触发 `startDrag` 方法，开始拖拽。在拖拽过程中，会触发 `onDrag` 方法，根据鼠标移动的距离来更新弹窗的位置。当用户释放鼠标左键时，会触发 `stopDrag` 方法，结束拖拽。

最后，我们在样式中添加了一些基本的样式规则，用于美化弹窗的外观。请注意，由于弹窗是绝对定位的，我们需要通过 JavaScript 来设置弹窗的初始位置和大小。在上面的代码中，我们将弹窗的位置设置为 `(50px, 50px)`，大小设置为 `(400px, 300px)`。如果需要修改弹窗的初始位置和大小，可以修改 `dialogStyle` 对象中的值。

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">

    <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 }">
      <div class="event-popup-body">
        <h2>{{ popupTitle }}</h2>

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,

        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({

          days.push({})
        }
        for (let i = 0; i < 35; i += 7) {

        if (this.currentMonth > 12) {
          this.currentMonth = 1
          this.currentYear++

          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 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
