在Magnific-Popup模式中显示PDF文件 [英] Display PDF file inside Magnific-Popup modal

问题描述

我的网站上有一个用户需要填写的表格才能生成PDF文件.如果表单中存在错误，则服务器将使用带有错误列表的json对象进行响应，否则将使用PDF文件(作为字符串)进行响应.我正在尝试在Magnific-Popup( https://www.npmjs. com/package/magnific-popup ).

I have a form on my website that the user needs to fill in order to generate a PDF file. If there are errors in the form, the server will respond with a json object with the list of errors, otherwise will respond with the PDF file (as a string). I'm trying to display that PDF file inside a Magnific-Popup (https://www.npmjs.com/package/magnific-popup).

    $('.preview-button').on('click', function (e) {
        event.preventDefault();
        var theLink     = $(this);
        var formElement = theLink.closest("form");

        $.ajax({
            url: theLink.attr('href'),
            method: 'GET',
            data: formElement.serialize(),
            success: function (response, textStatus, jqXHR) {
                var contentType = jqXHR.getResponseHeader("content-type") || "";
                if(contentType.indexOf('pdf') > -1){
                    // How can I tell to magnific popup to display the response as PDF?
                    $.magnificPopup.open({
                        // tell magnific popup to use the response...
                        type: 'iframe', 
                        closeOnBgClick: false
                    });
                }
                else{
                    if (response.hasOwnProperty('errors')){
                        // Form has error, show them
                        alert(response.errors);

                    }
                }
            }
        });

    });

推荐答案

这对于遇到相同问题的人可能很有用:我决定不发送pdf文件作为响应，而是决定在服务器中生成一个临时pdf文件，发送该文件的路径作为响应.然后，我们可以告诉magnificPopup将其显示在iframe中.

This might be useful for someone with the same problem: Instead of sending the pdf file as a response, I decided to generate a temporary pdf file in the server and send the path to that file as response. Then we can tell to magnificPopup to display it inside an iframe.
