vue可拖拽移动放大缩小的弹框组件

在Vue中创建一个可拖拽并且可以放大缩小的弹框组件，你可以使用基于Vue的第三方库如vuedraggable和vue-resizable。以下是一个简单的例子：

1. 安装所需库：

npm install vuedraggable vue-resizable

2. 创建Vue组件：

<template>
  <div>
    <draggable :options="dragOptions" @start="drag=true" @end="drag=false">
      <resizable :enable-native-drag="!drag" :class="{box: true, dragging: drag}" :style="style" @resizing="setSize">
        <div v-if="showHeader" class="header">
          <slot name="header">Header</slot>
        </div>
        <div class="content">
          <slot>Content</slot>
        </div>
      </resizable>
    </draggable>
  </div>
</template>
 
<script>
import draggable from 'vuedraggable';
import { Resizable } from 'vue-resizable';
 
export default {
  components: {
    draggable,
    Resizable
  },
  props: {
    showHeader: {
      type: Boolean,
      default: true
    },
    w: {
      type: Number,
      default: 200
    },
    h: {
      type: Number,
      default: 200
    }
  },
  data() {
    return {
      drag: false,
      size: {
        width: this.w,
        height: this.h
      }
    };
  },
  computed: {
    dragOptions() {
      return {
        animation: 200,
        group: "name",
        disabled: false,
        ghostClass: "ghost"
      };
    },
    style() {
      return {
        width: `${this.size.width}px`,
        height: `${this.size.height}px`
      };
    }
  },
  methods: {
    setSize(event) {
      this.size.width = event.size.width;
      this.size.height = event.size.height;
    }
  }
};
</script>
 
<style scoped>
.box {
  position: absolute;
  background: #eee;
  border: 1px solid #ccc;
}
 
.header {
  padding: 10px;
  background: #ddd;
  cursor: move;
  border-bottom: 1px solid #ccc;
}
 
.content {
  padding: 10px;
  cursor: move;
}
 
.dragging {
  cursor: move;
  z-index: 100;
}
 
.ghost {
  opacity: 0.5;
  background: #ccc;
}
</style>

3. 在父组件中使用这个弹框组件：

<template>
  <div id="app">
    <draggable-resizable-box :w="200" :h="100">
      <template #header>Custom Header</template>
      <p>Custom content...</p>
    </draggable-resizable-box>
  </div>
</template>
 
<script>
import DraggableResizableBox from './components/DraggableResizableBox.vue';
 
export default {
  components: {
    DraggableResizableBox
  }
};
</script>
 
<style>
#app {
  position: relative;
}
</style>

确保你已经安装了所需的库，并在你的主组件或应用
