Hello Keith!
The sample code you wrote works just fine!
I hadn’t understand the .send until
I saw it on your example..
And the tips for the Array creation and
the iteration of all objects with .each |do| really like me..
As you can see from my code I’m more
of structured programming, but I hope to develop a more Ruby style in my code…
and definitively you and many more people in this list are helping!
Sorry for my bad english, and thanks
again!

Subject: Re: [Wtr-general] Method
Names as variables?
It might be helpful if you
described what it is you are trying to accomplish. I have a feeling that there
are much easier ways to get what you are looking for than the approach you are
taking.
Then method I mentioned previously will in fact work for your line. It would
look like this:
if (todosdocs[i.to_s].send(propertie) == value
That said, a couple of quick notes on the code example:
- Other than the browser object, it does not
appear from the code sample that there is a need to make other variables
global (starting with $).
- You can create the array vector_fobjects simply
by saying
vector_fobjects
= []
You can certainly do Array.new instead, but there is no
need to create the object first and set it to nil. The same goes for the
vector_search variable.
3. As someone else noted, you have not initialized todosdocs anywhere
Again without knowing exactly what you are trying for, you might try this:
# assume you have $browser some defined and initialized someplace
def ENRA_FindObjects(propertie, value)
return_vector = []
all_objects = $browser.document.body.all
all_objects.each do |obj|
return_vector << obj if
obj.send(propertie) == value
end
return_vector
end
HTH,
Keith
(You will of course need to test this – I tried something similar in irb
and it looked like it would work)

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? 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)

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!
