如何在列中插入图像（jsPDF自动表格）？

4

我有一个问题，想在PDF文件中显示图片，但是PDF文件不接受该图片格式。我想添加插件来处理图片js代码。我尝试将图片进行编码，然后生成PDF文件，但是没有成功。以下是我的代码：

<head>
<script type="text/javascript" src="js/jspdf.min.js"></script>
<script type="text/javascript" src="js/jspdf.plugin.autotable.js"></script>
<script type="text/javascript" src="js/html2canvas.js"></script>
<script src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="js/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/function.js"></script>

<button onclick="generate()">Generate PDF</button>

<table id="mytable">
  <thead>
    <tr>
      <th>ID</th>
      <th>First name</th>
      <th>Last name</th>
      <th>Email</th>
      <th>Country</th>
      <th>Image</th>
    </tr>

将PDF配置逻辑移至生成函数中。

function generate() {
      var doc = new jsPDF();

  doc.autoTable({
    html: '#mytable',
    bodyStyles: {minCellHeight: 15},
    didDrawCell: function(data) {
      if (data.column.index === 5 && data.cell.section === 'body') {
         var td = data.cell.raw;
         var img = td.getElementsByTagName('img')[0];
         var dim = data.cell.height - data.cell.padding('vertical');
         var textPos = data.cell.textPos;
         doc.addImage(img.src, textPos.x,  textPos.y, dim, dim);
      }
    }
  });

      doc.save("table.pdf");
    }
