【解决方案1】：

您无法在表单的提交事件处理程序中获取按钮。

使用按钮单击事件处理程序来获取单击了哪个按钮并保存按钮的信息。

以下是如何做到这一点的答案：

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>
