AJAX调用返回数据，但不提示下载 [英] AJAX call returns data but does not prompt a download

问题描述

我有一个ajax调用，该调用成功地调用了一个本身正常工作的页面.单击按钮，然后下载PDF.但是，当我使用相同的请求类型和URL进行AJAX调用时，会返回data，但不会提示下载.

I have an ajax call that successfully calls a page that by itself works fine. You click the button, and a PDF downloads. However, when I make an AJAX call using the same request type and url, the data is returned, but does not prompt a download.

我的电话:

    $("#download-pdf").live('click', function(){
      $.ajax({
        url: $(this).parents('form').attr('action'),
        type: 'POST',
        success: function(data){
          console.log(data);
        }
      });
      return false;
    });

数据将作为未解析的PDF返回.所以我知道那里的信息.它只是不会导致下载.有什么花招吗?

Data is returned as what would be an unparsed PDF. So I know the information is there. It just doesn't cause a download. Any tricks?

推荐答案

强制下载的唯一方法是使用标准"表单提交方法刷新页面.使用Ajax，您将收到原始输出数据(PDF)，并且不会弹出任何保存对话框

The only way to force a download is to refresh the page using the "standard" form submission method. With Ajax you'll receive the raw output data (PDF) and no save dialog will ever pop up
