The downloadify plugin is meant to build the button for you to click on at page run time, so setting it up to run the downloadify script onclick is not going to work, instead add this and get rid of the button you made: downloadify插件旨在构建供您在页面运行时单击的按钮，因此将其设置为运行downloadify脚本onclick不会起作用，而是添加它并摆脱您所做的按钮：

<body onload="downloadPDF()">

My only other suggestion would be to use the jspdf.min.js found in the dist folder instead of just the standard jspdf.js file. 我唯一的其他建议是使用dist文件夹中的jspdf.min.js而不是仅使用标准jspdf.js文件。 The min folder contains all the plugins/functions needed to build the PDF. min文件夹包含构建PDF所需的所有插件/功能。 Keep including downloadify and swfobject though, they aren't included in that min build package. 尽管继续包括downloadify和swfobject，但它们不包含在该min build软件包中。

Note: I'm still trying to figure out how to get downloadify to add actual page content myself, the documentation is woefully poor. 注意：我仍在尝试自己如何获取downloadify来添加实际的页面内容，该文档非常糟糕。 When I put the code in to do so, literally nothing happens when I click the Save to Disk button, no console errors, no download happening, no nothing. 当我放入代码时，单击“保存到磁盘”按钮几乎没有任何反应，没有控制台错误，没有下载，也没有任何反应。

Also, you said you want to PRINT using jsPDF...but all jsPDF and downloadify do, is convert your page into a PDF file to download, not print. 另外，您说过要使用jsPDF进行打印...但是所有jsPDF和downloadify都可以将页面转换为PDF文件进行下载， 而不是打印。
