实现效果
实现原理：
- 方式一：通过
vue.extend实现 - 方式二：通过
new Vue()实现，本例采用该方法实现，比较简单，即新实例化一个vue对象，单独操作它。其实就是动态创建一个Vue实例对象。
代码实现
<!-- components/pop-share/pop-share.vue -->
<template>
<!-- 最外层需要一个透明遮罩，监听点击事件 -->
<div class="mo-mask" :style="{ 'z-index': zIndex }" @click="handleClose">
<transition name="el-fade-in-linear">
<div class="pop-share" :style="style" @click.stop="handleClick">
<div data-value="select" class="pop-share__item">
<i class="el-icon-share"></i>选中分享
</div>
<div data-value="all" class="pop-share__item">
<i class="el-icon-share"></i>全部分享
</div>
<div data-value="work-weixin" class="pop-share__item">
<i class="el-icon-position"></i>发送到企业微信
</div>
<div data-value="search" class="pop-share__item">
<i class="el-icon-search"></i>搜索
</div>
</div>
</transition>
</div>

// js获取当前窗口最大z-index

return maxZindex;

// components/pop-share/index.js
import Vue from 'vue';

// 所有实例列表

// 显示

// let PopShareVue = Vue.extend(PopShare);
// 此处需要使用 propsData传递参数

},
methods: {

}
}
function closeAll() {
for (let instance of instances) {

}
export default {
show,

将其挂载到Vue实例
// main.js
import Vue from 'vue';
import App from './App.vue';
import PopShare from './components/pop-share/index.js';
Vue.prototype.$popShare = PopShare;
const app = new Vue({
render: h => h(App)
}).$mount('#app');
调用弹出分享组件
<!-- App.vue -->
<template>
<div @mouseup="handleMouseUp" class="meeting-content" v-html="content"></div>
</template>
<script>
// created at 2022-06-21
export default {

data(){
return {
content: ""
}
},
methods: {
handleMouseUp(e) {
// 将当前鼠标的坐标传入
this.$popShare.show({
top: e.clientY,
left: e.clientX,
// 点击回调
onItemClick: e => {
console.log(e);
}
});
}
},
created() {
// this.getData();
}
};
</script>
<style lang="less">
.meeting-content {
white-space: pre-wrap;
