vue实现网页飘窗效果示例代码

需求说明

开发环境是vue，需要实现一个在网页上动态漂浮的窗口，漂浮到边界处，再弹回来。点击浮窗，可以跳转到新页面。

实现

Baywindow.vue

<template>
  <!-- 飘窗效果 -->
  <div
    id="thediv"
    ref="thediv"
    style="position: absolute; z-index: 111; left: 0; top: 0"
    v-show="thedivShow"
    @mouseover="clearFdAd"
    @mouseout="starFdAd"
  >
    <div
      style="
        cursor: pointer;
        text-align: right;
        font-size: 12px;
        color: #999999;
      "
      @click="thedivShow = false"
    >
      关闭
    </div>
    <a href="http://www.baidu.com" target="_blank"
      ><img src="../assets/111.jpg" width="320" border="0"
    /></a>
  </div>
</template>

注册使用
全局注册 在main.js中

// 注册为全局组件
import Baywindow from "@/views/Baywindow.vue";
Vue.component("Baywindow", Baywindow);

局部注册

<template>
  <div class="home">
    <Baywindow></Baywindow>
  </div>
</template>

<script>
import Baywindow from "@/views/Baywindow.vue";

export default {
  name: "Home",
  components: {
    Baywindow,
  },
};
</script>
