[Wtr-general] Method Names as variables?

[Michael Bolton]

You may be too bilingual; I see where alldocs is initialized, but I don't
see where todosdocs is initialized.

Hello Keith! 

Thanks for the quick answer, but I'm afraid that this is not what I'm
looking for.

I have written a function which search objects from a page, passing a
propertie and a value as parameters.

 

This is the function:

 

 

def ENRA_FindObjects(propertie, value)

   $vector_fobjects=nil

   $vector_fobjects=Array.new

   j=0

   alldocs=nil

   alldocs=$browser.document.body.all

   count=$browser.document.body.all.length

   $vector_search=nil

   $vector_search=Array.new

   for i in 0..count-1 do

      if (todosdocs[i.to_s]."#{propertie}=="#{value}") 

            $vector_search[j]=todosdocs[i.to_s]

            j+=1

        end

   end

   return($vector_search)

end

 

So, I load a page with a browser, and execute this function with, let's say:

 

array_objects=ENRA_FindObjects("className","button")

 

I hope the question is more clear now. 

 

How can I write this properly? -->
todosdocs[i.to_s]."#{propertie}=="#{value}" ,

In order that the propertie could be defined by a parameter?

 

 

Thank you so much for your time.

Cheers

 

Rodrigo Julian Martin

I am assuming Item(80) in your example is an object.

In Ruby, you can use the "send" method to call a function.

Example:

class MyClass
    def my_function
        puts "in my function"
    end
end

c = MyClass.new
function_name = "my_function"
c.send(function_name)

HTH,
Keith

Hello!
 
I have another code question.
 
Can I call an object method by using a variable?
 
I've tried something like this:
 
 
propertie="className"
a = Item(80).'#{propertie}'
 
And obviously doesn't work.
 
I've also tried: 
 
a = Item(80).{propertie}
 
but this is a call to a hash.
 
 
Any help would be really appreciated. 
Thanks in Advance!
