VUE实战6：鼠标悬停显示弹出窗口

这次介绍的控件相对比较简单，鼠标悬停时显示弹出内容，效果如下：

为了增加灵活性，用 slot 实现，调用时的代码：

<MouseOverPop class="toolbox-element">
  <template #heading>
    <div class="element-title"> 服务 </div>
  </template>
  <template #body>
    <div class="pop-content">
      <img style="width: 100%;" src="images/services.jpg" />
    </div>
  </template>
</MouseOverPop>

控件代码：

<template>
  <div class="mouse-over-pop" @mouseenter="mouseEnter" @mouseout="mouseOut">
    <slot name="heading"></slot>
    <div v-show="isActive" class="pop-body">
      <slot name="body"></slot>
    </div>
  </div>
</template>

<script> export default {
  name: 'MouseOverPop',
  data() { return {
      isActive: false };
  },

  methods: {
    mouseEnter() { this.isActive = true },
    mouseOut() { this.isActive = false },
  },
} 
</script>

css 代码：

.toolbox-element .element-title{
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
  cursor: default;
  color: #c2c2c2;
  font-size: 13px;
  padding:5px 5px;
  margin:3px;
  display: flex;
  flex-flow: row;
  justify-content: space-between;
  align-items: center;
}

.toolbox-element .element-title:hover{
  color: #75b325;
  box-shadow: 2px 2px 5px 0px rgba(0, 0, 0, 0.4); 
}

.toolbox-element{
}

.toolbox-element .pop-content{
  position: absolute;
  top:70px;
  left:100%;
  width: 320px;
  padding:10px;
  background: #eee;
}
