将生成的PDF文件存储在服务器上

我设法使用来解决此问题

FormData()

$(document).on("click", "#PDF", function () {    var table = document.getElementById("result");    var cols = [],        data = [];    function html() {        var doc = new jsPDF('p', 'pt');        var res = doc.autoTableHtmlToJson(table, true);        doc.autoTable(res.columns, res.data);        var pdf =doc.output(); //returns raw body of resulting PDF returned as a string as per the plugin documentation.        var data = new FormData();        data.append("data" , pdf);        var xhr = new XMLHttpRequest();        xhr.open( 'post', 'upload.php', true ); //Post to php script to save to server        xhr.send(data);    }    html();});

upload.php

if(!empty($_POST['data'])){    $data = $_POST['data'];    $fname = "test.pdf"; // name the file    $file = fopen("testa/pdf/" .$fname, 'w'); // open the file path    fwrite($file, $data); //save data    fclose($file);} else {    echo "No Data Sent";}

关键部分是

var pdf =doc.output();
