打印DIV的内容

打印DIV内容的最佳方法是什么?

当前回答

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。

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;
    }
  }

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…

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();

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;
    }

<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).
