如何在jsPDF中添加自动分页符和页脚？

Question

如何在打印页面时自动添加分页符，我在vuejs 2中使用jspdf插件，是否可以使用这些插件添加分页符？

目前，导出文件中的第二个 div 似乎已损坏，因此我希望 div 和页脚将从下一页出现。

这是我的代码：

.final-proof-container {
  width: 1296px;
  height: 775px;
  /* background-color: #e8e8e8; */

  border-left: 6px solid #383434;
  border-right: 6px solid #383434;
  /* padding: 10px 10px 10px 10px; */
  /* display: inline-flex;
  flex-direction: column;
  flex-wrap: wrap; */
}

Answer 1

atm，我没有看到任何支持打印 HTML 元素时分页的属性或函数，您只需通过

doc.addPage()

手动完成即可。

要在每个页面上添加页眉和页脚，您可以迭代文档的每个页面，然后将页眉和页脚附加到合适的位置。

例如：

for (let i = 1; i <= doc.getNumberOfPages(); i++) {
  doc.setPage(i)
  doc.text('This is header', 10, 30)
}
