Click a Canopy WebElement

Question

I have a button that I am retrieving with canopy like this...

let buttons = elements ".buttonClass"

The last button is the one I want to click, but when I do...

click buttons.tail

I get an error that says

"Can't click [OpenQA.Selenium.Remote.RemoteWebElement] because it is not a string or webelement"

So my question is, is there a way to do what I'm trying to do?

buttons.tail is not the "last button", but a list consisting of all buttons but the first one. That's what "tail" normally means in relation to lists. Try this:

let list = [1;2;3]
let tail = list.Tail   // tail = [2;3]

To get the last element of an F# list, use the List.last function:

let buttons = elements ".buttonClass"
click (List.last buttons)

What appeals to you the most: the awkward syntax or the inefficiency of traversing the list twice? – Fyodor Soikin Feb 24 '17 at 04:34
I was going to accept this answer but your comment seems a little snide. Thanks for your input. – DotNetRussell Feb 24 '17 at 15:48
_Your_ original comment (the one you've just removed) was "a little snide". This was my response. – Fyodor Soikin Feb 24 '17 at 16:37
@Anthony Russell, just curious, what was your comment? – FoggyFinder Feb 24 '17 at 18:32
I said I was going to go with my response but thank you... I don't think that was snide at all. I was being honest that I was accepting my response over yours. I hope that clarifies things. Thanks – DotNetRussell Feb 24 '17 at 18:59

The list that's returned with elements (selector) is an IWebElement List

So, by accessing the list with buttons.Item (buttons.Length - 1) I am able to access the WebElement object which has a click function on it.

let buttons = elements ".buttonClass"
(buttons.Item (buttons.Length - 1)).Click()

I suggest using `List.last buttons` or `buttons |> List.last`; it's a little easier to read. And easier to read, in the long run, means fewer bugs. – rmunn Feb 24 '17 at 23:59
