<div class="demo-image__preview"> <el-image style="width: 100px; height: 100px" ref="previewImg" :src="url" :preview-src-list="srcList"> </el-image> </div> <el-button type="danger" @click="viewBigPicture">点击按钮查看大图</el-button> <script lang="ts" setup> import { ref, computed, reactive, defineComponent } from 'vue' const previewImg = ref(null) const viewBigPicture = () =>{ previewImg.value.clickHandler() } </script>
