概述： 通过 event.composedPath() 拿到事件冒泡路径，再循环匹配 获取所需的dom

<template><div @click="handleClick"><div class="child child1"><button>Click Me</button><span>Click Me1</span><div>Click Me2</div></div><div class="child child1"><button>Click Me</button><span>Click Me1</span><div>Click Me2</div><div>Click Me3</div><p>clice</p></div></div>
</template><script>
export default {methods: {handleClick(event) {const composedPath = event.composedPath();// console.log('点击事件冒泡的 DOM 列表：', composedPath);for (const element of composedPath) { //  注意防止子级类名和父级类名相同 childif (element.classList && element.classList.contains('child')) {console.log('找到指定类名为 child 的 DOM 元素:', element);break;}}}}
};
</script>
