DOM-HTML API for Scala.js
================================
A collection of DOM-HTML bindings for Scala.js
### Description
A collection of DOM-HTML bindings for Scala.js
### Build Dependencies
* [SBT v1.2.x](http://www.scala-sbt.org/download.html)
### Build/publish the SDK locally
```bash
$ sbt clean publish-local
```
### Running the tests
Before running the tests the first time, you must ensure the npm packages are installed:
```bash
$ npm install
```
Then you can run the tests:
```bash
$ sbt test
```
### Examples
```scala
import io.scalajs.JSON
import scalajs.js
val result = JSON.parseAs[js.Object]("""{"x":5}""", { (key: js.Any, value: js.Any) => value }: js.Function)
println(JSON.stringify(result)) // {"x":5}
```
In some cases, the NodeList is a live collection, which means that changes in the DOM are reflected in the collection.
For example, Node.childNodes is live:
```scala
import io.scalajs.dom._
import io.scalajs.dom.html.browser._
val parent = document.getElementById[ParentNode]("parent")
val child_nodes = parent.childNodes
console.log(child_nodes.length); // let's assume "2"
parent.appendChild(document.createElement("div"))
console.log(child_nodes.length); // should output "3"
```
The following example shows how to create a URLSearchParams object from a URL string.
```scala
import io.scalajs.dom.html._
val searchParams = new URLSearchParams("key1=value1&key2=value2")
// Display the key/value pairs
for (value <- searchParams.values()) {
println(value)
}
```
The performance.now() method returns a DOMHighResTimeStamp, measured in milliseconds,
accurate to five thousandths of a millisecond (5 microseconds).
```scala
import io.scalajs.dom._
import io.scalajs.dom.html.browser._
def doSomething() {
// ...
}
val t0 = performance.now()
doSomething()
val t1 = performance.now()
console.log("Call to doSomething took " + (t1 - t0) + " milliseconds.");
```
### Artifacts and Resolvers
To add the `DOM-HTML` bindings to your project, add the following to your build.sbt:
```sbt
libraryDependencies += "io.scalajs" %%% "dom-html" % "0.5.0"
```
Optionally, you may add the Sonatype Repository resolver:
```sbt
resolvers += Resolver.sonatypeRepo("releases")
```
