POST with a parameter
websharperhtmlpost

I need to create a link that opens a new tab by posting a parameter to that page (on client-side)

let (|==>) (param_name, param_id) url =
    form [attr.target "_blank"; attr.action url; attr.id ("form" + param_id); attr.method "POST" ] [
            a [ on.click (fun el ev -> 
                    let frm = JS.Document.GetElementById ("form" + param_id) |> As<HTMLFormElement>
                    frm.Submit()
                ) ] [text param_id]
            input [attr.``type`` "hidden"; attr.name param_name; attr.value param_id] []
    ]

p [] [text "Now we test a post with a parameter"]
("sel_param_id", "12345") |==> "myurl"
p [] [text " ---- "]
p [] [text "Yet another test"]
("sel_param_id", "67890") |==> "myurl"

and from the opened page I need to read the parameter (on server-side)

let sel_param_id : string = string HttpContext.Current.Request.Form.["sel_param_id"]

The above code is fine to me and working as expected. I'm just asking if you have a more idiomatic and succinct way to do that in F# on WebSharper. Thank you very much.

A question about EndPoint: how can I get the url - let's say "/about" - from the EndPoint (e.g EndPoint.About) ? I'm asking because I want to share the EndPoint definition between Server and Client, so that I can define them in a common part (e.g. the Remoting.fs file) and then I want to get the url for the a ref in the Doc produced in the Client.fs. In that case I could use the EndPoint instead of the string in the function (|==>) above Is it possible to do that in F#?

Thank you!

ctx.Link gives you the URL from an endpoint, where ctx is the serving context.

Ok, I see.

let HomePage (ctx:Context<EndPoint>) =
    let  url = ctx.Link EndPoint.Table

Yeah, it works, ok, thank you
