使用mpdf通过AJAX生成PDF [英] Generating PDF via AJAX using mpdf
问题描述
我正在使用 mpdf库生成用户生成的HTML的PDF。我可以将PDF成功保存到服务器,但我希望在浏览器中为用户打开PDF。我尝试使用mpdf的输出选项在浏览器中打开文件或提示下载,但是当我使用AJAX将html数据发送到脚本时都没有发生。
I'm using the mpdf library to generate a PDF of user-generated html. I can get the PDF to save to the server successfully, but I want the PDF to open in the browser for the user. I've tried using mpdf's output options to open the file in the browser or to prompt a download, but neither happens when I use AJAX to send the html data to the script.
这是我的AJAX:
$('#save').click(function() {
var shelf_clone = $('#shelf').clone();
var shelf = shelf_clone.prop('outerHTML');
$.ajax({
type: "POST",
url: "pdf.php",
data: { html:shelf },
success: function(response)
{
$('#status').html('File Saved Successfully');
},
})
});
这是我的PDF生成脚本:
Here's my PDF-generating script:
<?php
include_once('/mpdf/mpdf.php');
$html = $_POST['html'];
$mpdf=new mPDF();
$stylesheet = file_get_contents('css/print.css');
$mpdf->WriteHTML($stylesheet,1);
$mpdf->WriteHTML($html,2);
$mpdf->Output('shelf.pdf', I);
exit;
?>
我正在使用AJAX,因此无需离开页面即可创建PDF。我的代码中是否有错误,或者我应该使用不同的方法?
I'm using AJAX so that the PDF can be created without having to navigate away from the page. Is there an error in my code or should I be using a different approach?
推荐答案
我最终没有使用AJAX,而是在表单上添加了一个隐藏的输入,并使用以下脚本填充它:
I ended up not using AJAX and instead added a hidden input on the form and populated it using the following script:
$('#save').click(function() {
event.preventDefault();
var shelf_clone = $('#shelf').clone();
var shelf = shelf_clone.prop('outerHTML');
$('#save_shelf input[name=shelf]').val(shelf);
$('#save_shelf').submit();
});
