[Wtr-general] Calling JavaScript code in the browser

[Egil Sorensen]

Thanks to Bill Attebery for pointing to a blog with a good solution to this
problem. I have experimented with making it easier to get any return value
back to Watir. This is what I came up with:

===================================
require 'watir'

module Watir
  class IE
    def execute_script(scriptCode)
      ie.Document.parentWindow.execScript("window.WatirJSResult =
"+scriptCode)
      return ie.Document.parentWindow.WatirJSResult
    end
  end
end

===================================

This allows for dropping an extra step in the test from the blog to relay
the result. The test now simply becomes:

===================================
def test_selection
  @ie.execute_script("RadComboBox1.FindItemByText(\"Golf\").Select()")
  assert_equal("Golf", @ie.execute_script("RadComboBox1.GetText()"))
end
===================================

I am no JavaScript expert, and I have only used this in a few small tests,
so I don't know if this will get me in trouble anywhere, though.
