javascript - 如何通过 JavaScript 在 Parse.com 中保存图像？

Question

我想在其列之一中添加包含图像的新对象，但它不保存我的照片，我的代码中是否有任何错误？特别是保存图像的一部分!!

出现问题的我的 JavaScript:

它从不在解析中上传我的照片!!

    <script type="text/javascript">
    Parse.initialize("key", "key");


   var products = Parse.Object.extend("products");

    var fileUploadControl = $("#profilePhotoFileUpload")[0];
if (fileUploadControl.files.length > 0) {
var file = fileUploadControl.files[0];
var name = "photo.png";

var parseFile = new Parse.File(name, file);
}
parseFile.save().then(function() {
  //The file has been saved to Parse.
   }, function(error) {
   // The file either could not be read, or could not be saved to Parse.
 });

    </script>

这里我添加了 html 行来上传文件:

<input type="file" id="profilePhotoFileUpload">

我得到了答案，我正在与你分享，也许有人会受益

THML上传文件的行是:

<input type="file" id="pic">

<script>中的代码在解析中获取和保存图像是:

     var fileUploadControl = $("#pic")[0];
   if (fileUploadControl.files.length > 0) {
   var file = fileUploadControl.files[0];
   var name = "photo.png";

   var parseFile = new Parse.File(name, file);

   //put this inside if {
   parseFile.save().then(function() {
   // The file has been saved to Parse.
   }, function(error) {
   // The file either could not be read, or could not be saved to Parse.
    });

    // Be sure of ur parameters name
    // prod is extend of my class in parse from this: var prod = new products();
    prod.set("picture", parseFile);
    prod.save();
   }
