问题描述
您好,我想生成特定div的PDF文件.为此,我发现jsPDF可能有用.我是jsPDF和bz Google的新手,我发现对我来说很好的代码行. jsPDF代码会将div转换为图像,然后将其另存为pdf. Mz问题是我在该div中有一个单选按钮,但是当我将div转换为PDF时,该页面的设计将类似于下图..
Hello I want to generate a PDF file of specific div. For that I found , jsPDF may be usefull. I am new to jsPDF and bz googling I found lines of code that will works fine for me. jsPDF code will convert div into an image and then it will save it as a pdf. Mz problem is that I have a radio button in that div but when I convert div into PDF , design of that page will be look alike below image..
我不知道确切的问题是什么.这是我编写的代码.
I dont know what is an exact issue. Here is code that I have written.
var imgData = canvas.toDataURL('image/png');
/*
Here are the numbers (paper width and height) that I found to work.
It still creates a little overlap part between the pages, but good enough for me.
if you can find an official number from jsPDF, use them.
*/
var imgWidth = 210;
var pageHeight = 295;
var imgHeight = canvas.height * imgWidth / canvas.width;
var heightLeft = imgHeight;
var doc = new jsPDF('p', 'mm');
var position = 0;
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
while (heightLeft >= 0) {
position = heightLeft - imgHeight;
doc.addPage();
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
}
doc.save('file.pdf');
