如何在列中插入图像(jsPDF自动表)？
提问于 2020-09-30 09:30:00
我有一个问题要在pdf文件中显示图像，pdf文件不接受图像format.Is想为图片添加插件js代码？我试着对图片进行编码，然后生成PDF文件，但它不起作用。下面是我的代码：
<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>

<script>
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);
}
}
});
function generate() {
doc.save("table.pdf");
}
</script>以下是我的输出：
希望有人能指导我解决这个问题。谢谢。

将pdf配置逻辑移动到生成函数。
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");
