Question

我想打印 bootstrap div 。

它在网络浏览器中正确显示但是当我点击打印按钮然后在打印预览时，元素是浮动的并且没有正确显示。

我该怎么做才能解决这个问题？

我想按照这种风格打印的Div

我在打印时获得的输出，我不希望在顶部的学校名称上看到

调用打印功能的按钮：

<button class="btn btn-default" onclick="printDiv('printableArea')"><i class="fa fa-print" aria-hidden="true" style="    font-size: 17px;"> Print</i></button>

打印功能：

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

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}

我要打印的Div

<div class="container right-container col-md-6" id="printableArea" style="display:block;">
    <span id="link7">   
        <div class="row">
            <div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
                <h3 id="school_title"><?php echo "$school_name";?> </h3>
                <p><p> 
                <p style="font-size: 1.1em;" id="exam_title">Annual Examination [ 2015-2016 ] <p> 
                <div class="row">
                    <div class="col-md-4">
                        <div class="header-time-date-marks">
                            <span id="exam_time">Time: 12 AM - 2 PM</span>
                            <span id="exam_date">Date: 30/12/2016</span>
                        </div>
                    </div>
                    <div class="col-md-8 header-time-date-marks" style="text-align: right;padding-right: 36px;">
                        <span id="exam_marks">100 Marks</span>
                    </div>
                </div>
            </div>
        </div>
        <hr / id="line" style="margin-top: 13px;">
        <div class="row q-question-type-style" id='question_section'>
        </div>
    </span>
</div>

查看此解决方案：它正在运行。 Div可以显示打印

将您的脚本标记放在html

之上

调用此函数：PrintElem（＆＃39; printableArea＆＃39;）

function PrintElem(elem){
        var mywindow = window.open('', 'PRINT', 'height=400,width=600');

        var css = "";
        var myStylesLocation = "${pageContext.request.contextPath}/ui/css/bootstrap.min.css";

        $.ajax({
            url: myStylesLocation,
            type: "POST",
            async: false
        }).done(function(data){
            css += data;
        }) 

        mywindow.document.write('<html><head><title></title>');
        mywindow.document.write('<style type="text/css">'+css+' </style>');
      //  mywindow.document.write('<link rel="stylesheet" href="${pageContext.request.contextPath}/ui/css/bootstrap.min.css" type="text/css" media="print"/>');
        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;
    }

Answer 3

您可以在css中尝试@media print。像吼叫一样

在css中

 @media print
   {
      p.bodyText {font-family:georgia, times, serif;}
      .noprint
      {
        display:none
      }
   }

在Html中

<div class="noprint">
I dont want it on print
</div>
<br><br>
<div>
Prrintable Area
</div>

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

Answer 5

我能够使用模版功能查找模态打印中不希望出现的部分，并隐藏它：


  print() {
    let mainLayout = document.querySelector('app-main-layout') as HTMLDivElement;
    mainLayout.style.display = 'none';

    window.print();

    mainLayout.style.display = 'unset';
  }

然后，使用以下CSS，使我的模式按钮消失：

@media print {
  button.close {display:none !important;}
}
