您无法在表单的Submit事件处理程序中获取该按钮。

使用按钮单击事件处理程序来获取单击的按钮并保存按钮的信息。

以下是解决方法：

var submitor = undefined;
$('.btn').click(function(e) {
    submitor = this;
})

$("#upload_form").submit(function(e) {
    var val = $(submitor).val();
    alert(val);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="upload_form" name="upload_form" enctype="multipart/form-data" method="post" style="width: 95%">
    <button type="submit" class="btn btn-success" id="btnUpload1" name="btnUpload" value="1"><span class="glyphicon glyphicon-cloud-upload"></span> Upload !</button>
    <button type="submit" class="btn btn-success" id="btnUpload2" name="btnUpload" value="2"><span class="glyphicon glyphicon-cloud-upload"></span> Upload !</button>
</form>
