scala.js facade to bootstrap-datepicker


Scala.js interface to bootstrap-datepicker

This library ScalaDatepicker is a Scala interface to the bootstrap-datepicker. From reference 1: "Bootstrap-datepicker is a jQuery plugin that provides a flexible datepicker widget in the Twitter bootstrap style." This bootstrap datepicker is one of a few datepicker that allows multi-dates to be selected.


ScalaDatepicker version 1.1 requires Scala.js 0.6.14.

This ScalaDatepicker version 1.2 requires Scala.js 0.6.18.

The original javascript bootstrap datepicker is required.


  1. A datepicker for twitter bootstrap (@twbs)


To use ScalaDatepicker include this in your build.sbt file:

libraryDependencies += "com.github.workingDog" %%% "scaladatepicker" % "1.2"

In addition you need to include the bootstrap-datepicker and jquery in your build dependencies. Typical setup:

libraryDependencies ++= Seq(
  "com.github.workingDog" %%% "scaladatepicker" % "1.2",
  "be.doeraene" %%% "scalajs-jquery" % "0.9.1",
  "org.webjars.bower" % "bootstrap-datepicker" % "1.7.0",   
  "org.webjars" % "jquery" % "3.2.1"      

Then use it as follows, note the the important implicit that converts jquery to the required type:

implicit def datepickerExt(jq: JQuery): Datepicker = jq.asInstanceOf[Datepicker]

object PickerApp extends JSApp {
  def main(): Unit = {
  // ensure the dom is ready
  jQuery(dom.document).ready(() => {
    // refering to an element with id = "scalaPicker"
    val jQ = jQuery("#scalaPicker")
    // construct a datepicker with some options
    jQ.datepicker(new DatepickerOptions {
        override val todayHighlight: js.UndefOr[Boolean] = true
        override val multidate: js.UndefOr[Boolean | Int] = true
    // use of a command with argument
    jQ.datepicker("setDate", "2016-10-08")
    // can also take a Date 
    jQ.datepicker("setDate", new Date(2016,10,8))
    // use of a command that returns a result
    val theDate = jQ.datepicker("getDate")
    println("theDate " + theDate)

Generally use ScalaDatepicker as you would the original bootstrap-datepicker.

Compiling and installation

To compile and generate a javascript file from the source code:

sbt fullOptJS 

The javascript file (scaladatepicker-opt.js) will be in the "./target/scala-2.12" directory.

To publish it to your local (Ivy) repository, simply type:

sbt publishLocal

Then include this in your build.sbt file

libraryDependencies += "com.github.workingDog" %%% "scaladatepicker" % "1.3-SNAPSHOT"


Refer to the original bootstrap-datepicker documentation.
