How can I use variable as a attribute name

ruby-talk
1

I'm unable to use the attribute name (variable) to verify the button
with the attribute value exists.

I've tried the following:

#Set Variables
$attribute_nm = "type"
$attribute_val = "submit"

#Verify Button Exists
if $ie.button(:$attribute_nm,$attribute_val).exists?

#Verify Button Exists
if $ie.button(:+$attribute_nm,$attribute_val).exists?

#Verify Button Exists
if $ie.button($attribute_nm,$attribute_val).exists?

Thanks,

DD

I assume from context that you're using Watir. I'm pretty sure Watir
is expecting a symbol there for the first argument, which is probably
why your attempts aren't working. Maybe try using the to_sym method
of the String class, like this:

if $ie.button($attribute_nm.to_sym,$attribute_val).exists?

Good luck,

Wow, that's a lot of global variables. If it's a symbol you want:
  irb(main):001:0> f = "foo"
  => "foo"
  irb(main):002:0> p f.to_sym, f.intern, :"#{f}"
  :foo
  :foo
  :foo

If it's a method call you're trying to do based on the variable, see
the Object#send method:

C:\>ri Object#send

------------------------------------------------------------
Object#send
     obj.send(symbol [, args...]) => obj
     obj.__send__(symbol [, args...]) => obj
------------------------------------------------------------------------
     Invokes the method identified by _symbol_, passing it any
arguments
     specified. You can use +__send__+ if the name +send+ clashes with
     an existing method in _obj_.

        class Klass
          def hello(*args)
            "Hello " + args.join(' ')
          end
        end
        k = Klass.new
        k.send :hello, "gentle", "readers" #=> "Hello gentle
readers"

Nice! That worked. This will save me tons of extra lines of Code.

Thanks Wade, Your the greatest.
