我有以下的code：

jQuery.post(encodeURI(ajaxurl + '?action=form_submission'), 
{ 'propertyID[]': propArray, submit: 'Export Gallery', NG_nonce: '<?php print    $this->nonce; ?>' },
function (result) {
   var obj = jQuery.parseJSON(result);
   if (typeof(obj['error']) == 'undefined') {
      if (typeof(obj['url']) != 'undefined') {
         window.location.href = obj['url'];
         var confirmBox = confirm('The gallery has been exported.');
      } else {
         alert('Error');
      }
   } else {
      alert(obj['error']);
   }
   if (redirect == 1)   {
        window.location.href = '/wp-admin/media-upload.php?post_id='+propertyID+'&type=image&tab=<?php print $_REQUEST['tab']; ?>';
   } else {
        jQuery(element).html(oldHtml);
   }
});

这完美的作品，它会创建，然后下载到用户的机器压缩文件夹。我需要做的就是添加标题信息，从而向用户提供的另存为对话框。我已经尝试了几种不同的东西（欲以request.setRequestHeader，其中包括在数据部分头信息），但我有没有运气。是否有人可以给我在这个正确的方向？谢谢。

This works perfectly, it creates a zipped folder that is then downloaded to the users machine. What I need to do is add header information so the user is given the 'save as' dialog box. I have tried several different things (trying to use request.setRequestHeader, including header information in the data portion) but I am having no luck. Can someone please send me in the correct direction on this? Thanks.

或者有前

window.location.href = obj['url']

我需要再次摸不着头脑，感谢您的帮助。

I need to figure this out, Thanks again for any help.

推荐答案

这另存为对话框是由浏览器。不同的浏览器将不同的方式处理文件下载。

This "save as" dialog is up to the browser. Different browsers will handle file downloads differently.
