ajax query problem

[Henry Story]

Hi I have been trying a little ajax query with the following code

    jQ.ajax(js.Dictionary(
      "url" -> "http://www.w3.org/People/Berners-Lee/card#i".asInstanceOf[js.Any],
      "success" ->  { (data: js.Any, textStatus: js.String, jqXHR: JQueryXHR) =>
        console.log(s"data=$data,text=$textStatus,jqXHR=$jqXHR");
        js.Dictionary().asInstanceOf[js.Dynamic]
      }.asInstanceOf[js.Any],
      "error" ->  { ( jqXHR: JQueryXHR, textStatus: js.String, errorThrow: js.String) =>
        console.log(s"jqXHR=$jqXHR,text=$textStatus,err=$errorThrow");
        js.Dictionary().asInstanceOf[js.Dynamic]
      }.asInstanceOf[js.Any],
      "type" -> "GET".asInstanceOf[js.Any]
    ).asInstanceOf[JQueryAjaxSettings]
    )

This fetches the url, but it does not call either the error or the success functions.

I used the 0.1 and the 0.2-SNAPSHOT compiler for this.

Any ideas?

Hi,

You cannot use .asInstanceOf[js.Any] like this and expect it to work. You have to use the appropriate implicit conversions, which are not no-ops for all types. So use ascription x: js.Any instead.

Cheers,
Sébastien

Thanks Sébastien, this worked:

    jQ.ajax(js.Dictionary(

      "url" -> {val str: js.Any = "http://www.w3.org/People/Berners-Lee/card"; str},

      "success" ->  { val res: js.Any =  test _; res },

      "error" -> { val res: js.Any = err _; res } ,

      "type" -> { val str: js.Any = "GET"; str }

    ).asInstanceOf[JQueryAjaxSettings]

    )

Not very beautiful of course. So I tried the JsObjectBuilder by Benjamin Jackman

     val json = jsObj(url = "http://www.w3.org/People/Berners-Lee/card",
            success =   (data: js.Any, textStatus: js.String, jqXHR: JQueryXHR) =>{
              console.log(s"data=$data,text=$textStatus,jqXHR=$jqXHR");
              js.Dictionary()
            },
            error =  ( jqXHR: JQueryXHR, textStatus: js.String, errorThrow: js.String) => {
              console.log(s"jqXHR=$jqXHR,text=$textStatus,err=$errorThrow");
              js.Dictionary()
            },
          `type` = "GET"
    )

which looks a lot better and compiles.

But it gives me a 

Uncaught TypeError: Object #<Object> has no method 'scala_Nothing'

Full code here: https://gist.github.com/bblfish/8121905

( It does go into the applyDynamicNamed part and write out 

  applyDynamicNamed(apply)(args: WrappedArray((url,http://www.w3.org/People/Berners-Lee/card), (success,function () { [native code] }), (error,function () { [native code] }), (type,GET))

)

I found the answer!

I had forgotten to type the result of jsObj! This works:

   val json = jsObj[org.scalajs.jquery.JQueryAjaxSettings](url = "http://www.w3.org/People/Berners-Lee/card",

            success =   (data: js.Any, textStatus: js.String, jqXHR: JQueryXHR) =>{
              console.log(s"data=$data,text=$textStatus,jqXHR=$jqXHR");
              js.Dictionary()
            },
            error =  ( jqXHR: JQueryXHR, textStatus: js.String, errorThrow: js.String) => {
              console.log(s"jqXHR=$jqXHR,text=$textStatus,err=$errorThrow");
              js.Dictionary()
            },
          `type` = "GET"
    )

    jQ.ajax(json)

All the best! :-)

Hi,

With 0.2-SNAPSHOT, you should now be able to write:

jQ.ajax(js.Dynamic.literal(

    url = "http://www.w3.org/People/Berners-Lee/card",
    success = { (data: js.Any, textStatus: js.String, jqXHR: JQueryXHR) =>
      console.log(s"data=$data,text=$textStatus,jqXHR=$jqXHR")

    },
    error = { (jqXHR: JQueryXHR, textStatus: js.String, errorThrow: js.String) =>
      console.log(s"jqXHR=$jqXHR,text=$textStatus,err=$errorThrow")
    },
    `type` = "GET"

).asInstanceOf[org.scalajs.jquery.JQueryAjaxSettings])

Cheers,

Sébastien
