如何让 jsPDF 从具有溢出设置的元素创建图像/pdf,以便它具有滚动条。以下示例粘贴到 addHTML Have a Play 页面 ( http://mrrio.github.io/jsPDF/ ) 只会为显示的 div 部分生成一个 pdf,即使我选择“中间”div:

var outer = document.createElement('div');
outer.style.height = "100px";
outer.style.overflow = "scroll";

var middle = document.createElement('div');

for ( var i=0; i<35;i++ ) {
var inner = document.createElement('div');
inner.style.border = "thick solid #0000ff";
inner.style.padding = "10px";

middle.appendChild(inner);
}

outer.appendChild(middle);
document.body.appendChild(outer);

var pdf = new jsPDF('p','pt','a4');

pdf.addHTML(outer,function() {
var string = pdf.output('datauristring');
$('.preview-pane').attr('src', string);
});

(基本上,这是创建一个带有滚动条的 div,在里面添加一个 div,然后在中间那个里面添加一大堆 div。有足够的滚动到屏幕之外,所以 pdf 不会拾取它们。我想弹出一个新窗口,但如果我这样做,我必须找出所有不同的样式表以拉入弹出窗口。)

最佳答案

看看这个讨论:https://github.com/MrRio/jsPDF/issues/270 :

I started working on a feature to breakup long HTML pages.

Try This: https://rawgit.com/Flamenco/jsPDF/text-html-table-page-break/examples/html2pdf/test-long-html-table.html

示例代码创建了一个长表并生成了一个 PDF。也许他的设置对你有用。

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Long Table</title>
</head>

<script src='../../libs/require/require.js'></script>
<script>
require_baseUrl_override = '../../';
require(['../../libs/require/config'], function(){
require(['jspdf.plugin.canvas', 'libs/html2pdf', 'libs/html2canvas/dist/html2canvas', 'libs/saveas'], function(){

var pdf = new jsPDF('p', 'pt', 'a3');

// Enable auto page wrap (there are still margin-top issues...)
pdf.context2d.pageWrapY = pdf.internal.pageSize.height-20;

// create a long table
var table = document.createElement('table');
for (var i=1; i<1000; i++){
var tr=document.createElement('tr');
var td=document.createElement('td');
td.innerHTML = "Item " + i;
tr.appendChild(td);
table.appendChild(tr);
}
document.body.appendChild(table);

// render body to pdf
html2pdf(document.body, pdf, function(){
pdf.save('Test.pdf');

});

}); // require
}); // require
</script>

<body>
</body>
</html>

代码有点乱,但是可以用。
