可以't fill_in value because Capybara don'看到弹出窗口

据我所知，当popup / modal打开时，它位于我打开它的页面顶部，因此当尝试填充值时，它看不到它需要做什么 .

然后尝试用 within 查看内部模态 . 尝试了其他课程，但同样 Capybara::ElementNotFound: Unable to find visible css "modal183"

within('modal183') do
        fill_in 'ctl00_ContentPlaceHolder1_tbId', :with => '10'
      end

尝试也找到xpath，但也没有 Capybara::ElementNotFound: Unable to find visible xpath "//input[@id='ctl00_ContentPlaceHolder1_tbId']"

<div class="modal183">
            <div class="popup_Titlebar" id="PopupHeader">

Updated: 附加部分看起来像是按下按钮后出现的弹出窗口 . 检查此代码上的代码显示 . 我没有编写这段代码，但试图在它们上构建自动化测试:)
