<p>这里用组件来示例</p><p><br></p><p><br></p><pre class="ql-syntax" spellcheck="false">import&nbsp;{&nbsp;defineComponent,&nbsp;onMounted,&nbsp;getCurrentInstance&nbsp;}&nbsp;from&nbsp;'vue' export&nbsp;default&nbsp;defineComponent({ &nbsp;&nbsp;name:&nbsp;'EbookReader', &nbsp;&nbsp;setup&nbsp;()&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;const&nbsp;{&nbsp;ctx&nbsp;}&nbsp;=&nbsp;getCurrentInstance() &nbsp;&nbsp;&nbsp;&nbsp;onMounted(()&nbsp;=&gt;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;const&nbsp;{&nbsp;fileName&nbsp;}&nbsp;=&nbsp;ctx.$router.currentRoute.value.params &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;console.log('fileName',&nbsp;fileName) &nbsp;&nbsp;&nbsp;&nbsp;}) &nbsp;&nbsp;} }) </pre><p><br></p><p><br></p><p><span class="ql-size-large">还有一种方式是引入import { useRouter } from 'vue-router'</span></p><p><br></p><p><span class="ql-size-large" style="color:rgb(230, 0, 0);">如果有大神还有更好的方法可以在下方留言。</span></p>
