Firefox文件上载窗口未显示

在我的Rails应用程序中,我的表单中有一个file_field输入,允许用户上传文件。当用户上传文件时,我使用ajax自动提交表单。它在Safari和Chrome中运行良好,但在Firefox中,当我点击“上传视频”按钮时,文件上传窗口(用户选择要上传的文件)从未出现,并且表单自动提交而没有任何文件

在Firefox中使用文件上传有什么特别之处吗?

这是我的代码:

    <div id="uploadVideoWrapper" title="Add Video">
      <button class="btn btn-primary uploadVideoButton">
        Upload Video
      </button>
      <input class="video_file_upload_field" id="video_video_path" name="video[video_path]" onchange="return validateFileExtension(this)" type="file">
    </div>

我的Ajax在用户上传文件后提交表单(video.js.coffee.erb):

jQuery ->
  $('#videoEmbedModal').fileupload
    dataType: "script"
    add: (e, data) ->
        console.log('uploaded video')
        types = /(\.|\/)(mov|mp4|avi)$/i
        file = data.files[0]
        size = file.size/(10e5)
        size_limit = 25 # file size limit is 50 mb
        if (types.test(file.type) || types.test(file.name)) && (size < size_limit)
            $('#video_submit').html('Saving...')
            $('#videoFileName').html(file.name)
            $('.uploadVideoButton').attr('disabled', true)
            $('.video_file_upload_field').attr('disabled', true)
            $('.loadingIcon').show()
            $('#images').append('<div class="placeholder video" style="background-image: none">uploading video...<br><%=image_tag("icons/loading.gif")%></div>');
            $('.placeholder').hide();
            data.context = $(tmpl("video-upload", file))
            # $('#videoUploadProgress').append(data.context)
            data.submit()
        else if (size > size_limit)
            alert("Your video is larger than 50 MB and cannot be uploaded.  Please upload to Youtube or Vimeo and embed your video instead.")
        else
            alert("#{file.name} is not a supported video format")
    progress: (e, data) ->
        if data.context
            progress = parseInt(data.loaded / data.total * 100, 10)            
            # data.context.find('.bar').css('width', progress + '%')
            if progress == 100
                setTimeout ( -> 
                    $('.embedModal').modal('hide');
                    ), 2000
                $('.placeholder').show();
                document.getElementById("images").scrollTop = document.getElementById("images").scrollHeight

事实证明输入偏离了我的按钮,因此用户在单击按钮时实际上没有点击输入字段。一个简单的解决方案,但需要一些时间来弄明白!
