打印<div id="printarea"></div> only?

如何打印指定的div(无需手动禁用页面上的所有其他内容)?

我想要避免一个新的预览对话框，所以用这个内容创建一个新窗口是没有用的。

该页面包含了几个表格，其中一个包含了我想打印的div -表格是用web的视觉样式设计的，不应该显示在打印中。

当前回答

基于@Kevin Florida的回答，我做了一种方法来避免当前页面上的脚本因为覆盖内容而禁用。我使用其他文件称为“printScreen.php”(或。html)。把你想打印的所有东西都包装在一个div“printSource”中。用javascript，打开一个你之前创建的新窗口(“printScreen.php”)，然后在顶部窗口的“printSource”中抓取内容。

这是代码。

主窗口:

echo "<div id='printSource'>";
//everything you want to print here
echo "</div>";

//add button or link to print
echo "<button id='btnPrint'>Print</button>";

<script>
  $("#btnPrint").click(function(){
    printDiv("printSource");
  });

  function printDiv(divName) {
   var printContents = document.getElementById(divName).innerHTML;
   var originalContents = document.body.innerHTML;
   w=window.open("printScreen.php", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=50,left=50,width=900,height=400");
   }
</script>

这是“printScreen.php”-另一个文件抓取内容打印

<head>
// write everything about style/script here (.css, .js)

</head>
<body id='mainBody'></body>
</html>


<script>
    //get everything you want to print from top window
    src = window.opener.document.getElementById("printSource").innerHTML;

    //paste to "mainBody"
    $("#mainBody").html(src);
    window.print();
    window.close();
</script>

试试这个:

function printElement($elem){
    var $customPrintSection = document.getElementById('customPrintSection'),
        $customPrintSectionCss = document.getElementById('customPrintSectionCss');

    if ($customPrintSection){
        $customPrintSection.remove();
    }

    if ($customPrintSectionCss){
        $customPrintSectionCss.remove();
    }

    $customPrintSection = document.createElement('div');
    $customPrintSection.id = 'customPrintSection';

    $customPrintSectionCss = document.createElement('style');
    $customPrintSectionCss.id = 'customPrintSectionCss';

    document.body.appendChild($customPrintSection);
    document.body.appendChild($customPrintSectionCss);

    $customPrintSection.innerHTML = $elem.innerHTML;
    $customPrintSectionCss.innerHTML = '@media screen { div#customPrintSection { display: none; } } @media print { body *:not(div#customPrintSection):not(div#customPrintSection *) { display: none; } div#customPrintSection a[href]:after { content: none !important; } }';

    window.print();

    $customPrintSection.remove();
    $customPrintSectionCss.remove();
}

我喜欢这个解决方案，因为它不像css解决方案那样影响整个页面，它在一个特定的答案中使所有主体元素立即不可见。所以如果需要的话，祝你能打印整页。

我也更喜欢“display: none”方法而不是“visibility: hidden”方法，所以没有必要将可打印元素设置为绝对元素并将其对齐到左上角。但我想这是主观的。

最后，它真的打败了新的窗口方法。

Give whatever element you want to print the id printMe. Include this script in your head tag: <script language="javascript"> var gAutoPrint = true; function processPrint(){ if (document.getElementById != null){ var html = '<HTML>\n<HEAD>\n'; if (document.getElementsByTagName != null){ var headTags = document.getElementsByTagName("head"); if (headTags.length > 0) html += headTags[0].innerHTML; } html += '\n</HE' + 'AD>\n<BODY>\n'; var printReadyElem = document.getElementById("printMe"); if (printReadyElem != null) html += printReadyElem.innerHTML; else{ alert("Error, no contents."); return; } html += '\n</BO' + 'DY>\n</HT' + 'ML>'; var printWin = window.open("","processPrint"); printWin.document.open(); printWin.document.write(html); printWin.document.close(); if (gAutoPrint) printWin.print(); } else alert("Browser not supported."); } </script> Call the function <a href="javascript:void(processPrint());">Print</a>

It's better solution. You can use it Angualr/React

Html

 <div class="row" id="printableId">
      Your html 
    </div>

Javascript

   function printPage(){
        
        var printHtml = window.open('', 'PRINT', 'height=400,width=600');
    
        printHtml.document.write('<html><head>');
        printHtml.document.write(document.getElementById("printableId").innerHTML);
        printHtml.document.write('</body></html>');
    
        printHtml.document.close(); 
        printHtml.focus(); = 10*/
    
        printHtml.print();
        printHtml.close();
    
        return true;
    
      }

@Kevin佛罗里达如果你有同一个类的多个div，你可以这样使用它:

 <div style="display:none">
   <div id="modal-2" class="printableArea">
     <input type="button" class="printdiv-btn" value="print a div!" />
   </div>
 </div>

我使用的是Colorbox内内容类型

$(document).on('click', '.printdiv-btn', function(e) {
    e.preventDefault();

    var $this = $(this);
    var originalContent = $('body').html();
    var printArea = $this.parents('.printableArea').html();

    $('body').html(printArea);
    window.print();
    $('body').html(originalContent);
});

我找到了解决办法。

@media print {
    .print-area {
        background-color: white;
        height: 100%;
        width: auto;
        position: absolute;
        top: 0;
        bottom: 0;
        left: 0;
        right: 0;
        z-index:1500;
        visibility: visible;
    }
    @page{
        size: portrait;
        margin: 1cm;
    }
/*IF print-area parent element is position:absolute*/
    .ui-dialog,
    .ui-dialog .ui-dialog-content{
        position:unset !important;
        visibility: hidden;
    }
}
