Ruby 使用Watir在HTML表中迭代和填充数据的更好方法

我有一个表，它可能包含多达50行和9列。然而，我用来填写表中数据的代码花费了很长时间

有没有更快的方法？ 这是我的密码

table = $browser.div(:id => "market").table(:id => 'tableTradeIndMarket')
  i = 3 + rand(1..table.rows.length-4)      

      table.rows[i].cells[4].select_list.select 'Buy'     
      table.rows[i].cells[5].select_list.select 'Market'          
      table.rows[i].cells[6].text_field.set ($share) 


      table.rows[i+1].cells[4].select_list.select 'Buy'       
      table.rows[i+1].cells[5].select_list.select 'Limit'     
      table.rows[i+1].cells[6].text_field.set ($share) 
      //To take out dollar sign which is found on the second column and put that value in to another column of the same row
      table.rows[i+1].cells[8].text_field.set(
        table.rows[i+1].cells[2].text[1..table.rows[i+1].cells[2].text.length]
      ) 

      table.rows[i+1].cells[9].select_list.select 'Day'  

      table.rows[i+2].cells[4].select_list.select 'Buy'       
      table.rows[i+2].cells[5].select_list.select 'Stop'      
      table.rows[i+2].cells[6].text_field.set ($share) 
      table.rows[i+2].cells[7].text_field.set ( table.rows[i+2].cells[2].text[1..table.rows[i+2].cells[2].text.length]) 
      table.rows[i+2].cells[9].select_list.select 'GTC'  

      table.rows[i+3].cells[4].select_list.select 'Buy'       
      table.rows[i+3].cells[5].select_list.select 'Stop/Limit'    
      table.rows[i+3].cells[6].text_field.set ($share) 
      table.rows[i+3].cells[7].text_field.set ( table.rows[i+3].cells[2].text[1..table.rows[i+3].cells[2].text.length]) 
      table.rows[i+3].cells[8].text_field.set ( table.rows[i+3].cells[2].text[1..table.rows[i+3].cells[2].text.length]) 
      table.rows[i+3].cells[9].select_list.select 'Day'

您的最佳选择可能是在Nokogiri的帮助下找到row元素。Željko Filipin在博客上发表了一篇关于这方面的好文章-

例如，第i行的输入为：

row_css = Nokogiri::HTML(browser.html).at_css("table#tableTradeIndMarket tr:nth-of-type(#{i})").css_path
row = browser.element(:css, row_css).to_subtype
row.cells[4].select_list.select 'Buy'     
row.cells[5].select_list.select 'Market'          
row.cells[6].text_field.set ($share) 

您可以对正在输入的其他行应用相同的概念

这至少对我使用的测试表有帮助。

您能提供HTML的源代码吗？
