<div>
<p id="ignorePDF">don't print this to pdf</p>
<p><font size="3" color="red">print this to pdf</font></p>

我尝试将调用函数放在页面底部，但仍然无法正常工作. 有人可以帮我吗?
i have tryied to put the calling function at the bottom of the page but it still don't work. Can someone help me?
推荐答案
由于您使用的是jQuery，请尝试:
Since you are using jQuery try:
$( document ).ready(function() {
//console.log( "ready!" );
PDF1();
});
也请注意:您可以使用(不是必需的):
Also Note: You could use (not required):
var source = $("body")[0];
