Twitter Typeahead (.js) module for Lift

Setup and Configuration

I currently only have builds for lift 2.5 and scala 2.10.x. If you need a different build let me know and I'll get one out, or you can send me a pull request

in build.sbt

resolvers ++= Seq(
  "snapshots" at "http://oss.sonatype.org/content/repositories/snapshots",
  "releases" at "http://oss.sonatype.org/content/repositories/releases"
)

add this to libraryDependencies

"net.liftmodules" %% "twittertypeahead_2.5" % "0.0.1-SNAPSHOT" % "compile"

Setup

In Boot.scala add

import net.liftmodules.{ TwitterTypeahead }

object Boot
  def boot = {
   ....
   TwitterTypeahead.init()
   ...
  }
}

You'll will also need

jQuery-1.9.1.min.js

typeahead.min.js

<script type="text/javascript" src="/scripts/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="/scripts/typeahead.min.js"></script>

Using Twitter Typeahead

It's pretty easy. There is current support for two modes: local and remote. The interface for each is the same. Here is an examle of each.

import net.liftmodules.typeahead.{TwitterTypeahead}

class TypeAhead {

  def render = {
    val local = List("red", "blue", "green", "orange", "purple", "white", "grey")
    val remote = List("foo", "bar", "baz")

    // stores candidates on the client's browser; sent on page load
    "@local *" #> TwitterTypeahead.local("colors", local, Empty, s =>  {}) &
    
    // tries to prefetch and store locally, if that fails it makes remote ajax requests on input
    "@remote *" #> TwitterTypeahead.remote("foo", remote, Empty, s =>  {})
  }
}

 /**
* Builds a Twitter Typeahead text input 
*
* @param name the name used on the input field
* @param candidates the candidates that are used for typeahead suggestions
* @param deflt the default value in the input field
* @param f the function that is called with the value of the input field on form post
*
* @return a text input field that hooked up to twitter typeahead
*/
TwitterTypeadhead.local(name: String, candidates: List[String], deflt: Box[String], 
  f: String => Any, attr: ElemAttr*)
  
TwitterTypeadhead.remote(name: String, candidates: List[String], deflt: Box[String], 
  f: String => Any, attr: ElemAttr*)

Future

Support custom styling
