打印DIV内容的最佳方法是什么?


当前回答

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);
}

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。

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
        newWin.document.write("<style type='text/css'>@media print{.dataTables_info,.dataTables_filter{height:0!important;width:0!important;margin:0!important;padding:0!important;min-height:0!important;line-height:0!important;overflow:visible!important;visibility:hidden}");
    //General Styling for Printing
        newWin.document.write("body {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:0;top:0!important;left:0!important;margin:0!important;orphans:0!important;widows:0!important;overflow:visible!important;page-break-after:always}");
    //Some forced styling in css rules includying page break for a div
        newWin.document.write("body h1{font-size:1em; font-family:Verdana;} a.marked{color:black; text-decoration:none} .pagebreak { page-break-before: always; } ");
        newWin.document.write("@page{size:A4; margin:2em; orphans:0!important;widows:0!important}}</style>\<\/head>\<body>");
        newWin.document.write(divToPrint.innerHTML);
        newWin.document.write("</body></html>");
        newWin.focus();
        newWin.print();
    }
    </script>

HTML >主体

<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).

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
