对早期版本进行了轻微更改 - 在CHROME上进行了测试
function PrintElem(elem)
{
var mywindow = window.open('', 'PRINT', 'height=400,width=600');
mywindow.document.write('<html><head><title>' + document.title + '</title>');
mywindow.document.write('</head><body >');
mywindow.document.write('<h1>' + document.title + '</h1>');
mywindow.document.write(document.getElementById(elem).innerHTML);
mywindow.document.write('</body></html>');
mywindow.document.close(); // necessary for IE >= 10
mywindow.focus(); // necessary for IE >= 10*/
mywindow.print();
mywindow.close();
return true;
}

我认为有更好的解决方案。使您的div打印覆盖整个文档，但仅在打印时：
@media print {
.myDivToPrint {
background-color: white;
height: 100%;
width: 100%;
position: fixed;
top: 0;
left: 0;
margin: 0;
padding: 15px;
font-size: 14px;
line-height: 18px;
}
}

虽然@gmcalab已经说过， 如果您使用的是jQuery，则可以使用我的printElement插件。
用法相当紧张，只需使用jQuery选择器抓取一个元素并打印出来：
$("myDiv").printElement();
希望它有所帮助！
答案 3 :(得分：21)
使用Jquery，只需使用此功能：
<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
}
</script>
您的打印按钮将如下所示：
<button id="print" onclick="printContent('id name of your div');" >Print</button>
编辑：如果您有需要保留的表单数据，克隆将不会复制该表单数据，因此您只需要获取所有表单数据并在还原后将其替换为：
<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
var enteredtext = $('#text').val();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
$('#text').html(enteredtext);
}
</script>

我使用Bill Paetzke答案打印包含图片的div，但它没有使用Google Chrome
我只需添加此行myWindow.onload=function(){即可使其正常工作，这里是完整的代码
<html>
<head>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
<script type="text/javascript">
function PrintElem(elem) {
Popup($(elem).html());
}
function Popup(data) {
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintElem('#myDiv')" />
</body>
</html>
如果有人只需要打印一个带有id的div，他就不需要加载jquery
这是执行此操作的纯JavaScript代码
<html>
<head>
<script type="text/javascript">
function PrintDiv(id) {
var data=document.getElementById(id).innerHTML;
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintDiv('myDiv')" />
</body>
</html>

var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr+footstr;
window.print();
document.body.innerHTML = oldstr;

创建一个单独的打印样式表，隐藏除要打印的内容之外的所有其他元素。加载时使用'media="print"标记它：
<link rel="stylesheet" type="text/css" media="print" href="print.css" />
这允许您为打印输出加载完全不同的样式表。
如果你想强制浏览器的打印对话框显示在页面上，你可以使用JQuery加载这样做：
$(function() { window.print(); });
或触发您想要的任何其他事件，例如用户点击按钮。

答案 17 :(得分：1)
注意：仅适用于启用jQuery的网站
这个很酷的技巧很简单。它适用于谷歌浏览器浏览器。 Firefox不允许您在没有插件的情况下打印到PDF。
var jq = document.createElement('script');
jq.src = "https://cdnjs.cloudflare.com/ajax/libs/jQuery.print/1.5.1/jQuery.print.min.js";
document.getElementsByTagName('body')[0].appendChild(jq)
$("#myDivWithStyles").print() // Replace ID with yours
逻辑很简单。我们正在创建一个新的脚本标记并将其附加到关闭body标记之前。我们在HTML中注入了jQuery打印扩展。使用您自己的Div标记ID更改 myDivWithStyles 。现在它需要准备一个可打印的虚拟窗口。
在任何网站上试用。只有警告有时候巧妙地写CSS会导致样式丢失。但我们大多数时候都会得到这些内容。

我修改了@BillPaetski的答案，使用querySelector，添加可选的CSS，删除强制的H1标签，并选择指定或从窗口中拉出标题。它也不会再自动打印并暴露内部结构，因此可以在包装函数中或根据需要切换它们。
只有两个私有变量是tmpWindow和tmpDoc，虽然我认为title，css和elem访问可能会有所不同，但应假设所有函数参数都是私有的。
码：function PrintElem(elem, title, css) {
var tmpWindow = window.open('', 'PRINT', 'height=400,width=600');
var tmpDoc = tmpWindow.document;
title = title || document.title;
css = css || "";
this.setTitle = function(newTitle) {
title = newTitle || document.title;
};
this.setCSS = function(newCSS) {
css = newCSS || "";
};
this.basicHtml5 = function(innerHTML) {
return '<!doctype html><html>'+(innerHTML || "")+'</html>';
};
this.htmlHead = function(innerHTML) {
return '<head>'+(innerHTML || "")+'</head>';
};
this.htmlTitle = function(title) {
return '<title>'+(title || "")+'</title>';

this.styleTag = function(innerHTML) {

这是真的老帖子，但这是我使用正确答案所做的更新。我的解决方案也使用jQuery。
重点是使用正确的打印视图，包括所有样式表以进行正确的格式设置，并且在大多数浏览器中也受支持。
function PrintElem(elem, title, offset)
{
// Title constructor
title = title || $('title').text();
// Offset for the print
offset = offset || 0;
// Loading start
var dStart = Math.round(new Date().getTime()/1000),
$html = $('html');
i = 0;
// Start building HTML
var HTML = '<html';
if(typeof ($html.attr('lang')) !== 'undefined') {
HTML+=' lang=' + $html.attr('lang');
}
if(typeof ($html.attr('id')) !== 'undefined') {
HTML+=' id=' + $html.attr('id');
}
if(typeof ($html.attr('xmlns')) !== 'undefined') {
HTML+=' xmlns=' + $html.attr('xmlns');
}
// Close HTML and start build HEAD
HTML+='><head>';
// Get all meta tags
$('head > meta').each(function(){
var $this = $(this),
$meta = '<meta';
if(typeof ($this.attr('charset')) !== 'undefined') {
$meta+=' charset=' + $this.attr('charset');
}
if(typeof ($this.attr('name')) !== 'undefined') {
$meta+=' name=' + $this.attr('name');
}
if(typeof ($this.attr('http-equiv')) !== 'undefined') {
$meta+=' http-equiv=' + $this.attr('http-equiv');
}
if(typeof ($this.attr('content')) !== 'undefined') {
$meta+=' content=' + $this.attr('content');
}
$meta+=' />';
HTML+= $meta;
i++;
}).promise().done(function(){
// Insert title
HTML+= '<title>' + title + '</title>';
// Let's pickup all CSS files for the formatting
$('head > link[rel="stylesheet"]').each(function(){
HTML+= '<link rel="stylesheet" href="' + $(this).attr('href') + '" />';
i++;
}).promise().done(function(){
// Print setup
HTML+= '<style>body{display:none;}@media print{body{display:block;}}</style>';
// Finish HTML
HTML+= '</head><body>';
HTML+= '<h1 class="text-center mb-3">' + title + '</h1>';
HTML+= elem.html();
HTML+= '</body></html>';
// Open new window
var printWindow = window.open('', 'PRINT', 'height=' + $(window).height() + ',width=' + $(window).width());
// Append new window HTML
printWindow.document.write(HTML);
printWindow.document.close(); // necessary for IE >= 10
printWindow.focus(); // necessary for IE >= 10*/
console.log(printWindow.document);
/* Make sure that page is loaded correctly */
$(printWindow).on('load', function(){
setTimeout(function(){
// Open print
printWindow.print();
// Close on print
setTimeout(function(){
printWindow.close();
return true;
}, 3);
}, (Math.round(new Date().getTime()/1000) - dStart)+i+offset);
});
});
});
}
稍后您简单需要这样的东西：
$(document).on('click', '.some-print', function() {
PrintElem($(this), 'My Print Title');
return false;
});

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
<!-- Page break -->
<div class="pagebreak"> </div>
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

与最佳答案相同，以防您需要像我一样打印图像：
如果您想要打印图像：
function printElem(elem)
{
Popup(jQuery(elem).attr('src'));
}
function Popup(data)
{
var mywindow = window.open('', 'my div', 'height=400,width=600');
mywindow.document.write('<html><head><title>my div</title>');
mywindow.document.write('</head><body >');
mywindow.document.write('<img src="'+data+'" />');
mywindow.document.write('</body></html>');
mywindow.print();
mywindow.close();
return true;
}

最好的方法是将div的内容提交给服务器并打开一个新窗口，服务器可以将这些内容放入新窗口。
如果这不是一个选项，您可以尝试使用客户端语言（如javascript）隐藏页面上除了div之外的所有内容然后打印页面...
