如何通过JavaScript在Parse.com中保存图像？ [英] How to save an Image in Parse.com via JavaScript?

问题描述

我想在其中一个列中添加包含Image的新Object，但它不能保存我的Pic，我的代码中是否有任何错误？特别是保存图像的一部分!!

I wanna add new Object that containing an Image in one of its columns , but it dose not save My Pic , Is there any mistake in my code ? specially part of saving Image !!

我出现问题的JavaScript：

My JavaScript where the problem appeared:

它永远不会上传我的图片解析!!

It never upload my pic in parse !!

    <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行上传文件：

Here I added html line to upload file:

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

推荐答案

我得到的答案我可能与你分享有人得到好处

I got the answer I am sharing it with you maybe someone get benefit

上传文件的 THML 行是：

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

< script> 中的代码在解析中获取并保存图像是：

The code in <script> to get and save image in parse is :

     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();
   }
