使用Firefox通过ajax发送FormData的问题

Question

我正在使用FormData发送multipart/form-data并在PHP中获取它，它可以在Chrome中正常运行，但在Firefox中无效。

这是我的JS

$.ajax({
    type: "POST",
    url: postUrl,
    dataType: "json",
    data: new FormData($("#form")[0]),
    processData: false,
    contentType: false,
    success: function (response) {
    }
});

我的HTML代码，

<form action="" method="post" enctype="multipart/form-data" id="form"> 
     <input type="text" class="form-control" value="" id="name" name="name">   
     <input type="file" id="resourceFile" name="resourceFile"> 
</form>

这是我的Php代码

echo $_POST["name"]  // name field is in form

In chrome I am getting value for name but in Firefox it's saying 
Undefined index: name.


This i am getting on print_r($_POST) for Firefox 
Array ( [-----------------------------183019406712953243052078205169 Content-Disposition:_form-data;_name] => "name" sdgdxgf -----------------------------183019406712953243052078205169-- ) 

This i am getting on print_r($_POST) for Chrome 
Array ( [name] => sdgdxgf )
