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。)

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。

// 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。
