uniapp实现有鼠标悬停

Uniapp是一款跨平台开发框架，可轻松实现多端应用的开发。要实现有鼠标悬停的效果，需要在uniapp中进行以下步骤：

在需要有悬停效果的元素上添加鼠标悬停事件。

<view @mouseover="hoverHandler">Hover me!</view>

在methods中添加hoverHandler方法来处理鼠标悬停事件。

methods: {
  hoverHandler() {
    console.log('Mouse is over me!');
    // do something
  }
}

可以根据需要在hoverHandler方法中实现具体的悬停效果，例如改变元素样式、显示提示信息等。

methods: {
  hoverHandler() {
    console.log('Mouse is over me!');
    this.isHovered = true;
  },
  leaveHandler() {
    console.log('Mouse is leaving me!');
    this.isHovered = false;
  }
}

完整代码示例如下：

<template>
  <view @mouseover="hoverHandler" @mouseleave="leaveHandler" :class="{hovered: isHovered}">Hover me!</view>
</template>

<script>
export default {
  data() {
    return {
      isHovered: false,
    }
  },
  methods: {
    hoverHandler() {
      console.log('Mouse is over me!');
      this.isHovered = true;
    },
    leaveHandler() {
      console.log('Mouse is leaving me!');
      this.isHovered = false;
    }
  }
}
</script>

<style>
.hovered {
  background-color: #eee;
  border: 1px solid #666;
}
</style>
