Parse.com只在一个循环中保存对象，只保存最后一个对象

问题描述：

I have the following code to save multiple objects to my parse.com table. I have debugged my code and everything should be working properly. This code is saving n objects all with the same information as the last object. The images are being save correctly.

Images and captions are just two arrays with the same length.

I am thinking the problem is because I have to wait for the callback from the previous save or the php code to finish. I am changing the image base on the fly as well.

I saw very similar problems posted but I tried the solution and it did not work: Parse.com save object once and here only first object getting saved in javascript for loop

Any idea what I am doing wrong here?

for(i = 0; i < images.length; i++){

            var caption = convert(captions[i]);

            //change image to base64
            $.post("base64.php", {base64: images[i]}, function(data){

                var image = data;

                var post = new Post();

                post.set("post", id);
                post.set("number", i + 1);
                post.set("by", by);
                post.set("title", title);
                post.set("description", description);
                post.set("caption", caption);
                post.set("views", 0);
                post.set("type", "image");

                var parseImage = new Parse.File("image.png", {base64: image});
                post.set("image", parseImage);

                post.save(null, {
                    success: function(messages) {

                    },error: function(messages, error) {

                    }
                });


            });
        }

我有以下代码将多个对象保存到我的parse.com表。我调试了我的代码和所有内容该代码使用与最后一个对象相同的信息保存n个对象。图像正确保存。 p>

图像和标题只是两个长度相同的数组。 p>

我在想这个问题是因为我有等待前一次保存或php代码的回调完成。我也在动态更改图像库。 p>

我发现了非常类似的问题，但我尝试了解决方案并且它不起作用： Parse.com保存对象一次并在此处只有第一个对象被保存在javascript for循环中 p>

我知道我是什么在这里做错了吗？ p>

  for（i = 0; i＆lt; images.length; i ++）{
 
 var caption = convert（captions [i]）; \  n 
 //将图像更改为base64 
 $ .post（“base64.php”，{base64：images [i]}，function（data）{
 
 var image = data; 
 
 var post  = new Post（）; 
 
 post.set（“post”，id）; 
 post.set（“number”，i + 1）; 
 post.set（“by”，by）; \  n post.set（“title”，title）; 
 post.set（“description”，description）; 
  post.set（“caption”，caption）; 
 post.set（“views”，0）; 
 post.set（“type”，“image”）; 
 
 var parseImage = new Parse.File  （“image.png”，{base64：image}）; 
 post.set（“image”，parseImage）; 
 
 post.save（null，{
 success：function（messages）{
 \  n}，错误：函数（消息，错误）{
 
} 
}）; 
 
 
}）; 
}

Batch them up:

var posts = [];
for(i = 0; i < images.length; i++){
    var caption = convert(captions[i]);

    //change image to base64
    $.post("base64.php", {base64: images[i]}, function(data){

        var image = data;

        var post = new Post();

        post.set("post", id);
        post.set("number", i + 1);
        post.set("by", by);
        post.set("title", title);
        post.set("description", description);
        post.set("caption", caption);
        post.set("views", 0);
        post.set("type", "image");

        var parseImage = new Parse.File("image.png", {base64: image});
        post.set("image", parseImage);

        // push to array for batch saving
        posts.push(post);
    });
}
Parse.Object.saveAll(posts)
.then(function() {
    console.log('all saved');
}, function(error) {
    console.error(error);
});

Parse.com只在一个循环中保存对象，只保存最后一个对象
