如果你想这样做：

$.upload( form.action, new FormData( myForm))
.progress( function( progressEvent, upload) {
    if( progressEvent.lengthComputable) {
        var percent = Math.round( progressEvent.loaded * 100 / progressEvent.total) + '%';
        if( upload) {
            console.log( percent + ' uploaded');
        } else {
            console.log( percent + ' downloaded');
        }
    }
})
.done( function() {
    console.log( 'Finished upload');                    
});

可能是您的解决方案。

这是我的代码

var formData = new FormData();
var files = $('input[type=file]');
for (var i = 0; i < files.length; i++) {
if (files[i].value == "" || files[i].value == null) {
 return false;
}
else {
 formData.append(files[i].name, files[i].files[0]);
}
}
var formSerializeArray = $("#Form").serializeArray();
for (var i = 0; i < formSerializeArray.length; i++) {
  formData.append(formSerializeArray[i].name, formSerializeArray[i].value)
}
$.ajax({
 type: 'POST',
 data: formData,
 contentType: false,
 processData: false,
 cache: false,
 url: '/Controller/Action',
 success: function (response) {
 if (response.Success == true) {
    return true;
 }
 else {
    return false;
 }
 },
 error: function () {
   return false;
 },
 failure: function () {
   return false;
 }
 });

我想到了一个主意：

Have an iframe on page and have a referencer.

具有将输入类型文件元素移动到的表单。

Form:  A processing page AND a target of the FRAME.

结果将发布到iframe，然后您只需将获取的数据发送到所需的图像标签，如下所示：

data:image/png;base64,asdfasdfasdfasdfa

并加载页面。

我相信这对我来说是有效的，取决于你是否能够做到：

.aftersubmit(function(){
    stopPropagation(); // or some other code which would prevent a refresh.
});

通过ajax上传文件不再需要Iframes。我最近自己做过。查看以下页面：

使用AJAX和jQuery上传HTML5文件

更新了答案并进行了清理。使用getSize函数检查大小或使用getType函数检查类型。添加了progressbar html和css代码。

var Upload = function (file) {
    this.file = file;
};

Upload.prototype.getType = function() {
    return this.file.type;
};
Upload.prototype.getSize = function() {
    return this.file.size;
};
Upload.prototype.getName = function() {
    return this.file.name;
};
Upload.prototype.doUpload = function () {
    var that = this;
    var formData = new FormData();

    // add assoc key values, this will be posts values
    formData.append("file", this.file, this.getName());
    formData.append("upload_file", true);

    $.ajax({
        type: "POST",
        url: "script",
        xhr: function () {
            var myXhr = $.ajaxSettings.xhr();
            if (myXhr.upload) {
                myXhr.upload.addEventListener('progress', that.progressHandling, false);
            }
            return myXhr;
        },
        success: function (data) {
            // your callback here
        },
        error: function (error) {
            // handle error
        },
        async: true,
        data: formData,
        cache: false,
        contentType: false,
        processData: false,
        timeout: 60000
    });
};

Upload.prototype.progressHandling = function (event) {
    var percent = 0;
    var position = event.loaded || event.position;
    var total = event.total;
    var progress_bar_id = "#progress-wrp";
    if (event.lengthComputable) {
        percent = Math.ceil(position / total * 100);
    }
    // update progressbars classes so it fits your code
    $(progress_bar_id + " .progress-bar").css("width", +percent + "%");
    $(progress_bar_id + " .status").text(percent + "%");
};

如何使用Upload类

//Change id to your id
$("#ingredient_file").on("change", function (e) {
    var file = $(this)[0].files[0];
    var upload = new Upload(file);

    // maby check size or type here with upload.getSize() and upload.getType()

    // execute upload
    upload.doUpload();
});

Progressbar html代码

<div id="progress-wrp">
    <div class="progress-bar"></div>
    <div class="status">0%</div>
</div>

Progressbar css代码

#progress-wrp {
  border: 1px solid #0099CC;
  padding: 1px;
  position: relative;
  height: 30px;
  border-radius: 3px;
  margin: 10px;
  text-align: left;
  background: #fff;
  box-shadow: inset 1px 3px 6px rgba(0, 0, 0, 0.12);
}

#progress-wrp .progress-bar {
  height: 100%;
  border-radius: 3px;
  background-color: #f39ac7;
  width: 0;
  box-shadow: inset 1px 1px 10px rgba(0, 0, 0, 0.11);
}

#progress-wrp .status {
  top: 3px;
  left: 50%;
  position: absolute;
  display: inline-block;
  color: #000000;
}

使用XMLHttpRequest（）确实可以进行AJAX上载。无需iframes。可以显示上载进度。

有关详细信息，请参阅：答案https://stackoverflow.com/a/4943774/873282对jQuery Upload Progress和AJAX文件上传提出质疑。

我用简单的代码处理了这些问题。您可以从这里下载工作演示

就你的情况而言，这些都是可能的。我将逐步介绍如何使用AJAX jquery将文件上传到服务器。

首先让我们创建一个HTML文件，添加如下表单文件元素，如下所示。

<form action="" id="formContent" method="post" enctype="multipart/form-data" >
         <input  type="file" name="file"  required id="upload">
         <button class="submitI" >Upload Image</button> 
</form>

其次，创建一个jquery.js文件，并添加以下代码来处理向服务器提交的文件

    $("#formContent").submit(function(e){
        e.preventDefault();

    var formdata = new FormData(this);

        $.ajax({
            url: "ajax_upload_image.php",
            type: "POST",
            data: formdata,
            mimeTypes:"multipart/form-data",
            contentType: false,
            cache: false,
            processData: false,
            success: function(){
                alert("file successfully submitted");
            },error: function(){
                alert("okey");
            }
         });
      });
    });
