打印DIV的内容

打印DIV内容的最佳方法是什么?

当前回答

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; ｝

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;
}

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();

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

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;
    }
  }

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)
  }   
}
