Question

我想打印一个没有按钮显示的特定div。当我使用document.body时，pdf按钮显示在里面。但是当我使用document.getElementById（“customers”）时，我得到的是一个带黑线的pdf。我需要一些帮助，因为我搜索并尝试了许多解决方案，但似乎没有任何效果。这是我的代码

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script type="text/javascript" src="script.js"></script>
        <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.0.272/jspdf.debug.js"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.js"></script>
    </head>
    <body>
        <div id="customers"> <!-- div that contains my table -->
            <table id="tab_customers" class="table table-striped">
                <colgroup>
                    <col width="20%">
                        <col width="20%">
                            <col width="20%">
                                <col width="20%">
                </colgroup>
                <thead>
                    <tr>
                        <th>Country</th>
                        <th>Population</th>
                        <th>Date</th>
                        <th>Age</th>
                    </tr>
                </thead>
                <tbody>
                    <tr>
                        <td>Chinna</td>
                        <td>1,363,480,000</td>
                        <td>March 24, 2014</td>
                        <td>19.1</td>
                    </tr>
                    <tr>
                        <td>India</td>
                        <td>1,241,900,000</td>
                        <td>March 24, 2014</td>
                        <td>17.4</td>
                    </tr>
                </tbody>
            </table>
        </div>
        <input type="button" value="save" onclick="javascript:saveAspdf()"/> <!-- call the js function -->
    </body>
</html>

的javascript：

/* js function reffering to jspdf to save a pdf */
    function saveAspdf() {
    var pdf = new jsPDF('p','pt','a4');
    pdf.addHTML(document.getElementById("customers"),function() {
        pdf.save('newDoc.pdf');
    });
    }

无法使用javascript在php中打印特定的div
