如何在 Javascript 中将 jsPDF 中的 PDF 文件保存在服务器上？

Question

 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>

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

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

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)}
            });
        }
    );
});

Here is the code for upload.php :

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