使用jspdf将PDF直接保存到文件 [英] Save pdf directly to file using jspdf
问题描述
我显示一个
面板
填充了<$我可以使用 postMessage
轻松地将输入发送到插件代码当我运行生成一个
pdf
下面的代码,并显示一个下载提示,这样我就可以选择目录来放置文件,但是我想直接把文件保存到一个文件中类似于:
doc.saveToFile(/ path / to / file)//我的插件代码中的自定义方法
这可以使用
jsPDF
对象吗? < HTML>
< head>
< script type ='text / javascript'src ='jspdf.source.js'>< / script>
< / head>
< body>
Hey
< script>
var doc = new jsPDF();
doc.text(20,20,'Hello bob');
doc.save('test.pdf');
< / script>
< / body>
< / html>
这应该适用于Firefox附加代码:
const {OS} = require(resource://gre/modules/osfile.jsm);
var pathToFile = OS.Path.join(path,to,file.pdf);
var doc = new jsPDF();
doc.text(20,20,'Hello bob');
var ab = doc.output('arraybuffer');
var u8 = new Uint8Array(ab);
OS.File.writeAtomic(pathToFile,u8).then(
function()
{
alert('File written!');
(e)
alert('Error'+ e);
}
);
如果您不使用附加SDK,而是使用普通扩展名,请将第一个符合:
const {OS} = Components.utils.import(resource://gre/modules/osfile.jsm ,{});

My script is a Firefox addon so has access to sensitive code like access to filesystem etc.
I display a Panel
populated with html
content, I could easily send input to the addon code using postMessage
When I run the code below a pdf
is generated and a download prompt is shown so i can select directory to place file, but I'd like to save the file using javascript directly to a file in background without the download prompt showing.
Something like: doc.saveToFile("/path/to/file") // custom method in my addon code
Would this be possible using the jsPDF
object?
<html>
<head>
<script type='text/javascript' src='jspdf.source.js'></script>
</head>
<body>
Hey
<script>
var doc = new jsPDF();
doc.text(20, 20, 'Hello bob');
doc.save('test.pdf');
</script>
</body>
</html>
This should work on your Firefox add-on code:
const { OS } = require("resource://gre/modules/osfile.jsm");
var pathToFile = OS.Path.join("path", "to", "file.pdf");
var doc = new jsPDF();
doc.text(20, 20, 'Hello bob');
var ab = doc.output('arraybuffer');
var u8 = new Uint8Array(ab);
OS.File.writeAtomic(pathToFile, u8).then(
function()
{
alert('File written!');
},
function(e)
{
alert('Error ' + e);
}
);
If you aren't using the Add-On SDK, but rather a normal extension, replace the first line with:
const { OS } = Components.utils.import("resource://gre/modules/osfile.jsm", {});
