An example of autocomplete with a server round trip to calculate the autocomplete list
The Lift Scala code to render the controls:
class Ajax { def sample(xhtml: NodeSeq): NodeSeq = { // local state for the counter var cnt = 0 // get the id of some elements to update val spanName: String = S.attr("id_name") openOr "cnt_id" val msgName: String = S.attr("id_msgs") openOr "messages" // build up an ajax <a> tag to increment the counter def doClicker(text: NodeSeq) = a(() => {cnt = cnt + 1; SetHtml(spanName, Text( cnt.toString))}, text) // create an ajax select box def doSelect(msg: NodeSeq) = ajaxSelect((1 to 50).toList.map(i => (i.toString, i.toString)), Full(1.toString), v => DisplayMessage(msgName, bind("sel", msg, "number" -> Text(v)), 5 seconds, 1 second)) // build up an ajax text box def doText(msg: NodeSeq) = ajaxText("", v => DisplayMessage(msgName, bind("text", msg, "value" -> Text(v)), 4 seconds, 1 second)) // bind the view to the functionality bind("ajax", xhtml, "clicker" -> doClicker _, "select" -> doSelect _, "text" -> doText _, "auto" -> JqSHtml.autocomplete("", buildQuery _, _ => ())) } private def buildQuery(current: String, limit: Int): Seq[String] = { Log.info("Checking on server side with "+current+" limit "+limit) (1 to limit).map(n => current+""+n) } def time = Text(timeNow.toString) }
