<body>
    //HTML Page //Other content you wouldn't like to print
    <input name="b_print" type="button" class="ipt" onClick="printdiv('div_print');" value=" Print ">

    <div id="div_print">

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;
    }

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;
    }
  }

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);
