如何使用Javascript将jsPDF中的PDF文件保存在服务器上?

问题描述：

var doc = new jsPDF();
$('#generatereport').click(function() {
   doc.fromHTML($('#lppresults')[0], 15, 15, {
	  width: 170
   }, function() {
	  doc.save('sample-file.pdf');
   });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
        
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.4/jspdf.min.js"></script>
<div class="survey-results" id="lppresults">
    <button id="generatereport">Download Report</button>
    <h1 style="border: solid;">TEST CONTENT</h1><br />
    <h1 style="border: solid;">TEST CONTENT1</h1>
</div>

我想使用JavaScript将文件保存在服务器上，但是目前我只能将此文件保存在用户的计算机上.

I want to save file on the server with JavaScript, but currently I can save this file only on the user's computer.

您必须使用

Instead of doc.save function you have to use doc.output function with type 'blob' as a parameter.

在Javascript部分:

In Javascript part:

var doc = new jsPDF();
$('#generatereport').click(function()
{
    doc.fromHTML(
        $('#lppresults'), 15, 15,
        {width: 170},
        function()
        {
            var blob = doc.output('blob');

            var formData = new FormData();
            formData.append('pdf', blob);

            $.ajax('/upload.php',
            {
                method: 'POST',
                data: formData,
                processData: false,
                contentType: false,
                success: function(data){console.log(data)},
                error: function(data){console.log(data)}
            });
        }
    );
});

这是upload.php的代码:

<?php
move_uploaded_file(
    $_FILES['pdf']['tmp_name'], 
    $_SERVER['DOCUMENT_ROOT'] . "/uploads/test.pdf"
);
?>
