前言
最近做了一个回单打印的功能、核心功能是、渲染出来的回单列表，用户可以浏览回单数据。可以同时勾选多个要打印的回单数据。将回单打印成pdf文件、同时下载保存到本地。核心就是将回单打印到本地。
效果展示
我将这个功能从项目中抽取出来了一个案例、演示预览和打印功能。核心就是调用这个打印的方法。你只关心传入要打印的模板和要打印的数据就可以了。
pdf打印
项目中实现的效果展示
用那个网站做出来的模板、添加相应的数据到代码中。直接调用打印方法就可以。一下是一些假数据
前提
这里是官网、可以设置要打印的模板。设置好要打印的模板、然后导出json数据、复制到项目代码中。具体使用过程请看官网介绍
过程
我这里直接给出完整的该打印插件、你只需要将该插件放到项目中，直接调用就行。具体如何调用、下文会说明。插件代码链接：我放在评论区置顶位置了
将插件代码放入项目中后，需要在项目中安装一些依赖。
cnpm install --save-dev jquery@3.3.1
cnpm install jquery-minicolors --save-dev
cnpm install bootstrap@3.4.1
cnpm install rgbcolor stackblur-canvas
提示：安装插件后，如果报jquery未定义的错误。就需要在配置文件中进行修改配置。具体如何配置，参考这篇博客：成功解决：jQuery is not defined
注意引用的地址、确保引入的地址正确。
拼接好的数据直接调用打印方法即可。
项目代码案例
这里是给出来如何使用插件进行数据的预览和打印、直接移入项目中，数据使用真实的数据就可以了。实现的效果如视频所示、这里将测试数据由三个改成一个。三个数据导致代码太长了。
