我在 pdf 文件中显示图像时遇到问题，pdf 文件不接受图像格式。要为图像 js 代码添加插件吗？我试图对图片进行编码然后生成 PDF 文件，但它不起作用。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>

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');

function generate() {
doc.save("table.pdf");

下面是我的输出:
希望有人能指导我如何解决它。谢谢。
最佳答案
将 pdf 配置逻辑移至 generate 函数。
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");
}
