Title: Re: [Wtr-general] Method Names as variables?

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

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? à 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!
