kandi X-RAY | Binding.scala Summary
Binding.scala is a data-binding library for Scala, running on both JVM and Scala.js. Binding.scala can be used as the basis of UI frameworks, however latest Binding.scala 12.x does not contain any build-in UI frameworks any more. For creating reactive HTML UI, you may want to check out html.scala, which is an UI framework based on Binding.scala, and it is also the successor of previously built-in dom library. See Binding.scala • TodoMVC or ScalaFiddle DEMOs as examples for common tasks when working with Binding.scala.

QUESTION
When using Binding.scala, I can not write html that uses the tabindex attribute. Is this a bug in Binding.scala / scala.js?
...ANSWER
Answered 2019-May-14 at 14:34You need to use the data:tabindex property. Please see https://scalafiddle.io/sf/TlcSdfF/1
QUESTION
I want to use Binding.scala in my Github Pages.
The Problem I have is that the value that I bind is not updated.
Here the example:
...ANSWER
Answered 2019-Apr-25 at 12:07The problem was that I included the ..-fastopt-bundle.js more than ones.
It looks like the second action was called on the other "JavaScript".
QUESTION
I'm failing to compile a simple example of Binding.scala, and being a newbie, I have no intuition how to fix it. Maybe the README is slightly outdated? The example at https://github.com/ThoughtWorksInc/Binding.scala-sample is even older and causes deprecation warnings.
My code, which I basically stuck together from the README, and even simplified a bit:
...ANSWER
Answered 2019-Mar-12 at 18:36Check that you have added this to your build.sbt
QUESTION
I want to define a checkbox in Binding.scala, like:
...ANSWER
Answered 2018-Dec-15 at 11:26According to https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes , in XHTML 5, any text values means true.
Fortunately, Binding.scala XML literals allows attributes of Boolean type. If elem.checked is false (not "false"), the attribute will be removed.
QUESTION
I tried to upgrade our applications which use Scaldi injection from Play 2.6.12 to Play 2.6.13. On all applications we run into the same problem.
It tries to instantiate an object of type '$$anon$1' or 'play.api.inject.BindingKey$$anon$1@5d807417' to be exact. This type obviously does not exist, so it does cause an error down in the Stack.
...ANSWER
Answered 2018-May-11 at 10:42I had run into exactly the same problem and found out this was caused by upgrading scala version in build.sbt (scala v2.12.6). I downgraded scala to v2.12.4 and it worked fine.
QUESTION
How can i use aria attributes in Binding.scala?
When compiling the following:
...ANSWER
Answered 2018-Apr-21 at 20:09All properties defined in scala-js-dom is automatically available for XHTML literals in Binding.scala.
However, such aria-checked property has not been defined in current version of scala-js-dom.
You can use custom attributes as a workaround:
QUESTION
I have a scala.js project. There I have a strange behavior with Scala.Meta and Binding.scala.
I want to create a case class from a case class:
...ANSWER
Answered 2018-Apr-21 at 20:13Macro annotation is deprecated (See https://github.com/scalameta/scalameta/issues/1182)
You can create an sbt plugin based on Scala Meta instead. See https://github.com/ThoughtWorksInc/sbt-example/ as an example to implement such a plugin.
To avoid incompatible versions, you should use the sbt's built-in Scala Meta, which is version 1.7.0.
QUESTION
I tried to declare some embedded css with Binding.scala
...ANSWER
Answered 2018-Mar-28 at 17:01You see the error message because { is a special character in Scala's XML literal.
Use a CDATA section in the style element.
QUESTION
I'm trying to build a generic router for a personal project by Binding.scala.
I've defined a PageState trait
ANSWER
Answered 2017-Nov-23 at 10:06route.state is only changed when unapply returns a Some(newState) and newState does not equal to the previous state.
In your case, unapply always returns Some(defaultState) or None. That's why route.state never changes.
QUESTION
The link [https://ccamel.github.io/playground-binding.scala/index.html#playground-binding.scala/home] has few demos of binding.scala I have used DomListner extension in chrome to understand the dom events. I found for each interaction there are hundreds of DOM events fired. For example one click on calculator button results in 114 events.
- It this a performance issue ?
- Does binding.scala library need performance improvements ?
- Does the code written using binding.scala need optimization ?
ANSWER
Answered 2017-Dec-29 at 18:26It's the expected behavior, because the DEMO that you mentioned recreated anchor elements, explicitly.
According to the Scaladoc for bind method:
Each time the value changes, in the current
@dommethod, all code after the currentbindexpression will be re-evaluated
As a result, the calc.bind call at here forces recreating the anchor element.
I created a pull request to change the class attribute instead, by avoiding the calc.bind call before XHTML literals.
