打印DIV内容的最佳方法是什么?
当前回答
只需使用PrintJS
let printjs = document.createElement("script");
printjs.src = "https://printjs-4de6.kxcdn.com/print.min.js";
document.body.appendChild(printjs);
printjs.onload = function (){
printJS('id_of_div_you_want_to_print', 'html');
}

这是我的jquery打印插件
(function ($) {
$.fn.printme = function () {
return this.each(function () {
var container = $(this);
var hidden_IFrame = $('<iframe></iframe>').attr({
width: '1px',
height: '1px',
display: 'none'
}).appendTo(container);
var myIframe = hidden_IFrame.get(0);
var script_tag = myIframe.contentWindow.document.createElement("script");
script_tag.type = "text/javascript";
script = myIframe.contentWindow.document.createTextNode('function Print(){ window.print(); }');
script_tag.appendChild(script);
myIframe.contentWindow.document.body.innerHTML = container.html();
myIframe.contentWindow.document.body.appendChild(script_tag);
myIframe.contentWindow.Print();
hidden_IFrame.remove();
});
};
})(jQuery);
我知道这是一个老问题，但我用jQuery解决了这个问题。
function printContents(id) {
var contents = $("#"+id).html();
if ($("#printDiv").length == 0) {
var printDiv = null;
printDiv = document.createElement('div');
printDiv.setAttribute('id','printDiv');
printDiv.setAttribute('class','printable');
$(printDiv).appendTo('body');
}
$("#printDiv").html(contents);
window.print();
$("#printDiv").remove();
}
CSS
@media print {
.non-printable, .fancybox-outer { display: none; }
.printable, #printDiv {
display: block;
font-size: 26pt;
}
}
HTML >头
<script type="text/javascript">
function printDiv() {
var divToPrint = document.getElementById('printArea');
//Firefox was just opening a new window with same content as opener and not performing the printing dialog, so needed to make it open a new instance of the window opener
newWin= window.open(self.location.href);
//We want to format the document appropriately
newWin.document.write("\<!DOCTYPE html\>\<html lang='es'\>\<head\>\<meta charset='utf-8'\/\>\<meta name='viewport' content='width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no'><meta http-equiv='X-UA-Compatible' content='IE=edge,chrome=1'\>\<meta name='HandheldFriendly' content='true'\/\>");
//HTML ELEMENTS THAT WE WANT TO HIDE FROM THE PRINTING AREA

<div id="printArea">
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).
</div>
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。当你加载它时，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一个完全不同的样式表。
如果你想强制浏览器的打印对话框出现在页面上，你可以在加载时使用JQuery这样做:
$(function() {window.print();})；
或者由你想要的任何其他事件触发，比如用户点击一个按钮。
我使用Bill Paetzke的答案打印一个div包含图像，但它不能与谷歌chrome
我只需要添加这一行myWindow.onload=function(){使它工作，这里是完整的代码
<html>
<head>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
<script type="text/javascript">
function PrintElem(elem) {
Popup($(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>
如果有人只是需要打印一个带有id的div，他不需要加载jquery
这里是做这件事的纯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>
我希望这能帮助到一些人
