Vue 实现浮动按钮（浮标）

使用 Vue 实现浮动按钮可以通过多种方式完成，以下是几种常见的方法：

使用 CSS 定位和 Vue 组件

创建 Vue 组件并配合 CSS 固定定位实现浮动按钮：

<template>
  <div class="float-button" @click="handleClick">
    {{ buttonText }}
  </div>
</template>

<script>
export default {
  props: {
    buttonText: {
      type: String,
      default: 'Click Me'
    }
  },
  methods: {
    handleClick() {
      this.$emit('click');
    }
  }
};
</script>

<style scoped>
.float-button {
  position: fixed;
  right: 20px;
  bottom: 20px;
  width: 60px;
  height: 60px;
  border-radius: 50%;
  background-color: #42b983;
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.2);
  z-index: 999;
}
</style>

使用 Vue 过渡动画

为浮动按钮添加动画效果：

<template>
  <transition name="fade">
    <div v-if="visible" class="float-button" @click="handleClick">
      {{ buttonText }}
    </div>
  </transition>
</template>

<script>
export default {
  props: {
    buttonText: String,
    visible: Boolean
  },
  methods: {
    handleClick() {
      this.$emit('click');
    }
  }
};
</script>

<style scoped>
.float-button {
  position: fixed;
  right: 20px;
  bottom: 20px;
  width: 60px;
  height: 60px;
  border-radius: 50%;
  background-color: #42b983;
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.2);
  z-index: 999;
}

.fade-enter-active, .fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}
</style>

使用第三方库

利用 Vue 的 UI 组件库如 Vuetify 或 Element UI 快速实现：

<template>
  <v-btn
    fab
    dark
    fixed
    bottom
    right
    color="primary"
    @click="handleClick"
  >
    <v-icon>add</v-icon>
  </v-btn>
</template>

<script>
export default {
  methods: {
    handleClick() {
      this.$emit('click');
    }
  }
};
</script>

实现拖拽功能

为浮动按钮添加拖拽功能：

<template>
  <div
    class="float-button"
    @mousedown="startDrag"
    @touchstart="startDrag"
    :style="{ left: left + 'px', top: top + 'px' }"
    @click="handleClick"
  >
    {{ buttonText }}
  </div>
</template>

<script>
export default {
  data() {
    return {
      left: window.innerWidth - 80,
      top: window.innerHeight - 80,
      dragging: false,
      startX: 0,
      startY: 0
    };
  },
  props: {
    buttonText: String
  },
  methods: {
    startDrag(e) {
      this.dragging = true;
      this.startX = e.clientX || e.touches[0].clientX;
      this.startY = e.clientY || e.touches[0].clientY;
      document.addEventListener('mousemove', this.onDrag);
      document.addEventListener('touchmove', this.onDrag);
      document.addEventListener('mouseup', this.stopDrag);
      document.addEventListener('touchend', this.stopDrag);
    },
    onDrag(e) {
      if (!this.dragging) return;
      const clientX = e.clientX || e.touches[0].clientX;
      const clientY = e.clientY || e.touches[0].clientY;
      this.left += clientX - this.startX;
      this.top += clientY - this.startY;
      this.startX = clientX;
      this.startY = clientY;
    },
    stopDrag() {
      this.dragging = false;
      document.removeEventListener('mousemove', this.onDrag);
      document.removeEventListener('touchmove', this.onDrag);
    },
    handleClick() {
      if (!this.dragging) {
        this.$emit('click');
      }
    }
  }
};
</script>

<style scoped>
.float-button {
  position: fixed;
  width: 60px;
  height: 60px;
  border-radius: 50%;
  background-color: #42b983;
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.2);
  z-index: 999;
  user-select: none;
}
</style>
