我希望在收到请求后立即以pdf格式下载该页面。这是我的脚本：
<script>
pdfdoc.fromHTML($('#container').html(), 10, 10, {
'width': 110,
'elementHandlers': specialElementHandlers
});
pdfdoc.save('Invoice.pdf');
</script>
但是控制台出现错误未捕获的ReferenceError：未定义pdfdoc在？id = 5：435我已经在标题中链接了脚本该如何解决？
您需要定义一个变量pdfdoc var doc = new jsPDF（）;并且您还需要添加jspdf.min.js文件。
请尝试以下代码：
<div id="content">
<h3>Sample h3 tag</h3>
<p>Sample pararaph</p>
</div>
<div id="editor"></div>
<button id="cmd">Generate PDF</button>
<script src="https://code.jquery.com/jquery-1.12.3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/0.9.0rc1/jspdf.min.js"></script>
<script>
var doc = new jsPDF();
var specialElementHandlers = {
'#editor': function (element, renderer) {
return true;
}
};
$('#cmd').click(function () {
doc.fromHTML($('#content').html(), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
</script>
能否请您尝试以下代码
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-1.12.3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.0.272/jspdf.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.5.0-beta4/html2canvas.min.js"></script>
</head>
<body>
<div id="content">
<style>
p{
font-size:27px;
}
</style>
<h3>Sample h3 tag</h3>
<p style="color:red;">Sample pararaph</p>
</div>
<div id="editor"></div>
<button id="cmd">Generate PDF</button>
<script>
window.onload=function(){
$('#cmd').click(()=>{
var pdf = new jsPDF();
pdf.addHTML(document.getElementById("content"),function() {
pdf.save('web.pdf');
});
})
}
</script>
</body>
</html>
