Question

我遇到的问题是我在方法上调用click_no_wait方法控件显示“文件下载”框。它适用于第一次。我使用Auto It来处理文件下载框并保存文件在特定位置。现在，当我尝试使用时 click_no_wait在同一控件上，它不会显示文件下载框，但如果我在调用click_no_wait之前刷新浏览器，它将显示“文件下载”框。所以，我的问题是它是自动它没有被释放的情况因此click_no_wait不能找到控件或实现有什么问题 click_no_wait方法。

环境：操作系统：Microsoft XP SP2 Ruby：ruby 1.8.6 patchelevel 398 Watir：1.8.1

以下是我使用控件的方式

def click_export_button 
  control = browser.button(:id,'export-button') 
  $DEBUG = true 
  #browser.refresh         #- If this line is not commented, the dialog appears 
  control.click_no_wait    #-- I replace click_no_wait with click and/or click! and the code freezes, so the control is found 
  download_file("C:\\test.csv") 
  $DEBUG = false 
end

以下是下载文件的代码

def download_file(filePath = nil) 
  autoIt = WIN32OLE.new("AutoItX3.Control") 
  timeout = 10 
  fileDownloadWindowTitle = "File Download" 
  handle = autoIt.WinWait(fileDownloadWindowTitle, "Do you want to open or save this file?", timeout) 
  retVal = nil 
  unless (handle.eql? @autoItError) 
    autoIt.WinActivate(fileDownloadWindowTitle) 
    autoIt.ControlClick(fileDownloadWindowTitle, "", "&Save") 
    saveWindowTitle = "Save As" 
    windowHandle = autoIt.WinWaitActive(saveWindowTitle, "", timeout) 
    if (windowHandle == 1) 
      retVal = save_file(saveWindowTitle, autoIt, filePath) #-- function to save the file to the location 
    end 
  else 
    puts "Unable to download the file" 
  end 
  autoIt.ole_free 
  return retVal 
end

这是我得到的错误

ruby -e "$:.unshift('c:/ruby/lib/ruby/gems/1.8/gems/watir-1.8.1/lib/ 
watir/win32ole').unshift('c:/ruby/lib/ruby/gems/1.8/gems/

您可以尝试在click_no_wait之前添加以下内容：

"browser.refresh"

当autoIt用于处理文件下载框时，click_no_wait第二次不起作用
