}
</script>

六、示例

<template><div v-if="show" class="showCourseWare"><div class="showCourseWareHeader"><span class="title">{{ "文件预览页面标题" }}</span><spantitle="下载文档"class="el-icon-download"@click="downloadDocument"></span><span title="关闭预览" class="el-icon-close" @click="closeWin"></span></div><div class="showCourseWareContainer"><div class="showCourseWareBox" v-if="showDocument"><!-- DOCX文档 --><divv-if="showWord"class="showCourseWareContent"ref="wordContainer"></div><!-- PDF文档 --><divv-else-if="showPDF"class="showCourseWareContent"id="pdfContainer"></div><!-- PPTX文档 --><divv-else-if="showPPT"class="showCourseWareContent"ref="pptContainer"id="pptContainer"></div></div><div class="showVideoBox" v-if="showVideo"><video controls :src="videoSrc"></video></div></div></div>
</template><script>
