打印DIV的内容

打印DIV内容的最佳方法是什么?

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中。

如果这不是一个选项，你可以尝试使用客户端语言，如javascript隐藏页面上的所有内容，除了div，然后打印页面…

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:

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。

2010-02-12 21:51:46

打开一个新窗口打开新窗口的文档对象，并在其中写入一个简单的文档，其中只包含您已经获得的div和必要的html头文件等-您可能还希望将文档拉入样式表，这取决于您的内容是什么在新页面中放入一个脚本来调用window.print() 触发脚本

与早期版本相比略有变化-在CHROME上测试

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;
}

注意:从下面提到的插件编写到现在已经有13年了，就像评论中提到的那样。它不再工作，因为改变了API在jQuery。随意分叉和添加一个拉请求!

虽然这是@gabe说的，如果你正在使用jQuery，你可以使用我的printElement插件。

这里有一个示例，以及关于插件的更多信息。

使用方法相当简单，只需用jQuery选择器抓取一个元素并打印它:

$("#myDiv").printElement();

我希望这能有所帮助!

我认为有更好的解决办法。让你的div打印覆盖整个文档，但只在打印时:

@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;
    }
}

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);

function printdiv(printdivname) {
    var headstr = "<html><head><title>Booking Details</title></head><body>";
    var footstr = "</body>";
    var newstr = document.getElementById(printdivname).innerHTML;
    var oldstr = document.body.innerHTML;
    document.body.innerHTML = headstr+newstr+footstr;
    window.print();
    document.body.innerHTML = oldstr;
    return false;
}

这将打印您想要的div区域，并将内容设置为原来的内容。Printdivname是要打印的div。

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;
    }
  }

在Opera中，试试:

    print_win.document.write('</body></html>');
    print_win.document.close(); // This bit is important
    print_win.print();
    print_win.close();

与最佳答案相同，以防你需要像我一样打印图像:

如果你想打印图像:

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;
    }

虽然@BC的答案最好打印一页。

但要打印多页A4大小的同时按ctrl+P以下解决方案可能会有所帮助。

@media print{
html *{
    height:0px!important;
    width:0px !important;
    margin: 0px !important;
    padding: 0px !important;
    min-height: 0px !important;
    line-height: 0px !important;
    overflow: visible !important;
    visibility: hidden ;


}


/*assing myPagesClass to every div you want to print on single separate A4 page*/

 body .myPagesClass {
    z-index: 100 !important;
    visibility: visible !important;
    position: relative !important;
    display: block !important;
    background-color: lightgray !important;
    height: 297mm !important;
    width: 211mm !important;
    position: relative !important;

    padding: 0px;

下面是一个适用于IE和Chrome的IFrame解决方案:

function printHTML(htmlString) {
    var newIframe = document.createElement('iframe');
    newIframe.width = '1px';
    newIframe.height = '1px';
    newIframe.src = 'about:blank';

    // for IE wait for the IFrame to load so we can access contentWindow.document.body
    newIframe.onload = function() {
        var script_tag = newIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        var script = newIframe.contentWindow.document.createTextNode('function Print(){ window.focus(); window.print(); }');
        script_tag.appendChild(script);

        newIframe.contentWindow.document.body.innerHTML = htmlString;
        newIframe.contentWindow.document.body.appendChild(script_tag);

        // for chrome, a timeout for loading large amounts of content
        setTimeout(function() {
            newIframe.contentWindow.Print();
            newIframe.contentWindow.document.body.removeChild(script_tag);
            newIframe.parentElement.removeChild(newIframe);
        }, 200);
    };
    document.body.appendChild(newIframe);
}

使用Jquery，简单地使用这个函数:

<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
}
</script>

你的打印按钮看起来是这样的:

<button id="print" onclick="printContent('id name of your div');" >Print</button>

编辑:如果你有表单数据，你需要保留，克隆不会复制，所以你只需要抓取所有的表单数据，并在恢复后替换它如下:

<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>
<textarea id="text"></textarea>

我认为目前提出的解决方案有以下缺点:

CSS媒体查询解决方案假设只有一个div要打印。 javascript解决方案只适用于特定的浏览器。破坏父窗口内容并重新创建会造成混乱。

我改进了上面的解决方案。下面是我测试过的一种方法，效果非常好，有以下好处。

适用于所有浏览器，包括IE, Chrome, Safari和firefox。不会破坏和重载父窗口。可以在页面上打印任意数量的DIV。使用HTML模板避免容易出错的字符串连接。

注意事项:

必须在新创建的窗口上有一个onload="window.print()"。不要从父类调用targetwindow.close()或targetwindow.print()。确保执行targetwindow.document.close()和target.focus() 我使用的是jquery，但你也可以使用简单的javascript做同样的技术。你可以在这里看到它的行动https://math.tools/table/multiplication。通过单击框头上的打印按钮，可以分别打印每个表。

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

创建一些通用的东西用于任何HTML元素

HTMLElement.prototype.printMe = printMe;
function printMe(query){             
     var myframe = document.createElement('IFRAME');
     myframe.domain = document.domain;
     myframe.style.position = "absolute";
     myframe.style.top = "-10000px";
     document.body.appendChild(myframe);
     myframe.contentDocument.write(this.innerHTML) ;
     setTimeout(function(){
        myframe.focus();
        myframe.contentWindow.print();
        myframe.parentNode.removeChild(myframe) ;// remove frame
     },3000); // wait for images to load inside iframe
     window.focus();
}
//usage
document.getElementById('xyz').printMe();
document.getElementsByClassName('xyz')[0].printMe();

希望这能有所帮助。

公认的解决方案不起作用。Chrome打印了一个空白页面，因为它没有及时加载图像。这种方法是有效的:

编辑:看来接受的解决方案在我发布后被修改了。为什么会投反对票?这个解决方案也同样有效。

    function printDiv(divName) {

        var printContents = document.getElementById(divName).innerHTML;
        w = window.open();

        w.document.write(printContents);
        w.document.write('<scr' + 'ipt type="text/javascript">' + 'window.onload = function() { window.print(); window.close(); };' + '</sc' + 'ript>');

        w.document.close(); // necessary for IE >= 10
        w.focus(); // necessary for IE >= 10

        return true;
    }

我修改了@BillPaetski答案使用querySelector，添加可选的CSS，删除强制H1标签，并使标题可选地指定或从窗口拉出。它也不再自动打印，并公开内部内容，以便它们可以在包装器函数中切换或随你喜欢。

仅有的两个私有变量是tmpWindow和tmpDoc，尽管我相信标题，css和elem访问可能会有所不同，但应该假设所有函数参数都是私有的。

Code:

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) {
        return '<style>'+(innerHTML || "")+'</style>';
    };

    this.htmlBody = function(innerHTML) {
        return '<body>'+(innerHTML || "")+'</body>';
    };

    this.build = function() {
        tmpDoc.write(
            this.basicHtml5(
                this.htmlHead(
                    this.htmlTitle(title) + this.styleTag(css)
                ) + this.htmlBody(
                    document.querySelector(elem).innerHTML
                )
            )
        );
        tmpDoc.close(); // necessary for IE >= 10
    };

    this.print = function() {
        tmpWindow.focus(); // necessary for IE >= 10*/
        tmpWindow.print();
        tmpWindow.close();
    };

    this.build();
    return this;
}

Usage:

DOMPrinter = PrintElem('#app-container');
DOMPrinter.print();

注意:这只适用于启用jQuery的站点

这个很酷的技巧非常简单。它在谷歌Chrome浏览器中为我工作。火狐不允许你在没有插件的情况下打印PDF文件。

首先，使用(Ctrl + Shift + I) / (Cmd + Option + I)打开检查器。在控制台中输入以下代码:

var jqchild = document.createElement('script');
jqchild.src = "https://cdnjs.cloudflare.com/ajax/libs/jQuery.print/1.5.1/jQuery.print.min.js";
document.getElementsByTagName('body')[0].appendChild(jqchild);
$("#myDivWithStyles").print(); // Replace ID with yours

它启动打印对话框。打印出来或者保存成PDF格式(chrome)。完成了!

逻辑很简单。我们正在创建一个新的脚本标记，并将其附加在关闭主体标记的前面。我们在HTML中注入了一个jQuery打印扩展。用你自己的Div标签ID更改myDivWithStyles。现在它负责准备一个可打印的虚拟窗口。

在任何网站上尝试一下。唯一需要注意的是，有时巧妙地编写CSS会导致丢失样式。但大多数时候我们得到的是内容。

2017-12-07 10:02:16

如果你想拥有原始文档的所有样式(包括内联样式)，你可以使用这种方法。

复制完整的文档将body替换为要打印的元素。

实现:

class PrintUtil {
  static printDiv(elementId) {
    let printElement = document.getElementById(elementId);
    var printWindow = window.open('', 'PRINT');
    printWindow.document.write(document.documentElement.innerHTML);
    setTimeout(() => { // Needed for large documents
      printWindow.document.body.style.margin = '0 0';
      printWindow.document.body.innerHTML = printElement.outerHTML;
      printWindow.document.close(); // necessary for IE >= 10
      printWindow.focus(); // necessary for IE >= 10*/
      printWindow.print();
      printWindow.close();
    }, 1000)
  }   
}

下面的代码复制了查询选择器目标的所有相关节点，复制了它们在屏幕上看到的样式，因为许多用于css选择器目标的父元素将会丢失。如果有很多带有很多样式的子节点，这将导致一些延迟。

理想情况下，你应该有一个打印样式表，但这是为用例，没有打印样式表插入，你希望打印在屏幕上看到。

如果您在此页的浏览器控制台中复制以下项目，它将打印此页上的所有代码片段。

这是一个非常老的帖子，但这里是我的更新，我使用正确的答案。我的解决方案也使用jQuery。

这一点是使用正确的打印视图，包括所有样式表的正确格式，也要在大多数浏览器支持。

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);
            });
        });
    });
}

之后你只需要这样的东西:

$(document).on('click', '.some-print', function() {
    PrintElem($(this), 'My Print Title');
    return false;
});

试一试。

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');
}

这应该可以工作:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;
     document.body.innerHTML = printContents;
     window.print();
     document.body.innerHTML = originalContents;
}

有点晚了，但我发现这真的很好!!

function printDiv(divID) {
    //Get the HTML of div
    var divElements = document.getElementById(divID).innerHTML;
    //Get the HTML of whole page
    var oldPage = document.body.innerHTML;

    //Reset the page's HTML with div's HTML only
    document.body.innerHTML = 
       "<html><head><title></title></head><body>" + 
              divElements + "</body>";

    //Print Page
    window.print();

    //Restore orignal HTML
    document.body.innerHTML = oldPage;
          
}

<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">&nbsp;</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).

将Element传递给这个函数打印:

函数printElm(elm) { var orig = document.body.innerHTML; document.body.innerHTML = elm.outerHTML; print (); document.body.innerHTML = origin; ｝

2022-06-25 12:12:42

function printDomElement(element) {
    element.classList.add("printCss");

    let printId = "printId";
    let name = ".printCss";
    let rules = "-webkit-print-color-adjust:exact;height:100%;width:100%;position:fixed;top:0;left:0;margin:0;";

    var style = document.createElement('style');
    style.id = printId;
    style.media = "print";
    document.getElementsByTagName('head')[0].appendChild(style);

    if (!(style.sheet || {}).insertRule)(style.styleSheet || style.sheet).addRule(name, rules);
    else style.sheet.insertRule(name + "{" + rules + "}", 0);

    window.print();

    setTimeout(() => {
      element.classList.remove("printCss");
      let elem = document.getElementById(printId);
      if (elem) elem.remove();
