SpreadJS支持PDF文件导出,即通过 savePDF 方法的 Workbook 类将工作簿(扩展名为.xlsx的Excel文件)导出PDF格式(扩展名为.pdf的文件)。
下表列出了 savePDF 方法的参数:
参数 | 描述 |
---|---|
successCallback | 导出到pdf操作成功后调用此函数。 |
errorCallback | 发生错误时调用此函数。 |
options | 导出PDF文件时,可以从以下选项中进行选择: |
sheetIndex | 通过指定要导出的表单索引,可以将工作簿中的特定表单导出PDF。 如果未指定此参数,则默认情况下将导出所有可见的表单。 |
导出PDF操作使用 printInfo 对象进行页面设置,并支持SpreadJS中所有可用的打印功能。
有关自定义导出PDF文件的更多信息,请参见Custom PDF Export.
导出PDF文件时,您可以指定要嵌入到PDF文档中的字体。 用户可以嵌入标准字体(下面列出)和自定义字体(通过注册新字体)以进行PDF导出。
有关如何在执行导出PDF操作时嵌入自定义字体的更多信息,请参见Use Custom Font for PDF Export.
下表列出了PDF文档中支持的十四种标准字体:
Courier | Courier | Courier-Bold | Courier-Oblique | Courier-BoldOblique | |

本示例说明了如何使用 savePDF 方法将Excel文件导出PDF文件。 导出的文件以.pdf扩展名保存。
代码的第一部分列出了执行“导出到PDF”操作的依赖项。
代码的第二部分说明了 savePDF 方法可用于导出PDF格式。
<script src='.../spreadjs/gc.spread.sheets.all.x.xx.xxxxx.x.min.js' type='text/javascript'></script>
<script src='.../spreadjs/plugins/gc.spread.sheets.print.x.xx.xxxxx.x.min.js' type='text/javascript'></script>
<script src='.../spreadjs/plugins/gc.spread.sheets.pdf.x.xx.xxxxx.x.min.js' type='text/javascript'></script>
spread.savePDF(function (blob) {
var fileName = $('#fileName').val() || 'download';
saveAs(blob, fileName + '.pdf');
}, function (error) {
console.log(error);
}, {
title: 'Test Title',
author: 'Test Author',
subject: 'Test Subject',
keywords: 'Test Keywords',
creator: 'test Creator'
});
注意: 导出PDF时应牢记以下几点:
1) 为了导出到excel文件,用户需要参考文件: gc.spread.sheets.pdf...*.min.js
2) 图像未经过base64编码。 因此,当用户使用文件协议方案时,它们可能不会导出。 用户在执行导出操作时必须使用http或https协议方案。
