[Wtr-general] Can anybody tell what the mean of 'ie.document.frames.length' is and how it changes

[jim che]

Below is my code

 

require 'watir'
include Watir

require 'methods/login'

$au3 = WIN32OLE.new("AutoItX3.Control")
  $au3.Opt("MouseCoordMode",0)

admin_login("admin","123456")

$ie.link(:text,"License generation").click

sleep(1)
puts "ie.document.frames.length is "
puts $ie.document.frames.length                            ####### the system will print 0
table = $ie.table(:index, 6)
tableCel = table.body(:index, 1)[3][1].focus()
$au3.Send("{TAB 2}{ENTER}")

sleep(10)
puts "ie.document.frames.length is "
puts $ie.document.frames.length                            ######## the system will print nil

table1 = $ie.table(:index, 6)
tableCel1 = table1.body(:index, 1)[12][1].focus()
$au3.Send("{TAB 2}{ENTER}")

sleep(1)
puts "ie.document.frames.length is "
puts $ie.document.frames.length                          ####### the system will print 1
a = $ie.contains_text("Please at least enter information into one of the domain and IP address fields")
b = $ie.contains_text("This information is required")
puts a

if a && b
    puts "the information of 'Domain', 'IpAddress' and 'Quantity of CAL' fields are required"
else
    puts "some errors appeared..."
end

$ie.text_field(:name,"domain").set("a.com")
$ie.text_field(:name,"ipAddress").set("1.1.1.1")
$ie.text_field(:name,"calQuantity").set("aaa")

table1 = $ie.table(:index, 6)
tableCel1 = table1.body(:index, 1)[12][1].focus()
$au3.Send("{TAB 2}{ENTER}")
sleep(1)
c = $ie.contains_text("This information should be numeric")
if c
   puts "'Quantity of CAL' should be numeric"
   puts "test of form_validation is successful"
else
   puts "some errors appeared..."
end  
puts "ie.document.frames.length is "
puts $ie.document.frames.length                            ####### the system will print 1

 

 

As you see above in the four parts of this code I print the value of 'ie.document.frames.length'

and the value was changed I want to know what the 'ie.document,frames,length' means and why the value turned to 'nil' in the second part

Thank you very much
