Question

如何从表单中获取文件以将其保存到Parse？我尝试了几十种变体：

SELECT COUNT(rating_draft_result.id), u1.username, u2.username 
FROM rating_draft_result
INNER JOIN users u1 ON rating_draft_result.user_id =  u1.id
INNER JOIN users u2 ON rating_draft_result.result = u2.id
GROUP BY u1.username, u2.username

并在javascript中：

<form id="image_form" enctype="multipart/form-data" action="/upload/image" method="post">
          <h3>Upload icon image: </h3>
          <p><input id="image_file" name="image_file" type="file"></p>
          <p><input id="event_submit" type="submit" value="Create"  onclick="makeEventSnip();"></p>
</form>

我尝试按照他们在Parse的JS指南（https://parse.com/docs/js/guide）中所说的方式去做，但这也不起作用。它似乎没有从表单中抓取任何东西。我错过了什么？

试试这个

 var fileUploadControl =  document.getElementById('image_file');
    var file = fileUploadControl.files[0];
    var name = "icon.png";
    var iconImageFile = new Parse.File(name, file);
     iconImageFile.save().then(function() {//you need to call after save the file
      alert(iconImageFile._url);
     }

使用Javascript上传Parse.File
