.submit()不包含隐藏字段

将jQuery .submit() post绑定到dropzone file upload complete handler会导致所有正确的数据被发送，除了它丢失了隐藏的输入字段。代码均为php和jquery/js

找不到任何关于为什么这些会被排除。

所有隐藏字段都在表单中，并且有名称和id填充

<code>
<form id="payments" method="post" action="<?php $_SERVER['PHP_SELF'] ?>" class="form-horizontal" >
<input type="hidden" name="transID" value="<? if(isset($values['transID'])){echo $values['transID'];}else{ echo $transID; } ?>" />
<input type="hidden" name="transID" value="<? if(isset($values['transID'])){echo $values['transID'];}else{ echo $transID; } ?>" />
<input type="hidden" id="pdflink" name="pdflink" value="<? if(isset($values['pdflink'])){echo $values['pdflink'];} ?>" />
<input type="button" name="btnSubmit" value="Submit PDF & Payment(s)" onclick="this.disabled" id="btnSubmit" class="col-md-6 btn btn-primary raised" />
</form>
