Does Playframework 2.0.x support in templat

Question

I wonder if play 2.0.3 and higher supports else if in views? I only read that one have to code that way: if {...}else{if{...}else{...}} cannot believe that.

Answer 1

The @Todd Flanders answer is right. In a wrapper @{}, you can write your normal Scala code. Example

@{
  if (profile.sex == 0) {
    <p class="col-md-6">Other</p>
  } else if (profile.sex == 1) {
    <p class="col-md-6">Male</p>
  } else {
    <p class="col-md-6">Female</p>
  }
}

Answer 2

I was also able to get

@{if (true) "foo" else if (true) "bar" else "baz"}

to work. Keep in mind that most programming languages do not support "else if" as a lexical token. They are separate commands. The block of code executed by the "else" command happens to be an "if" statement.

Note also that you can mix XHTML with the clause:

 @{if (true) <b>foo</b> else if (false) "bar" else "baz"}

I agree with biesior that it's usually a good idea to push state logic into the controller, then you can have different views for different states, with shared components having their own sub-views.

Answer 3

No, "else if" is not supported in scala templates: Does play framework 2.0 support nested if statement in template?

You can use pattern matching or you can put if inside else.

Answer 4

Now if else if is supported in latest playframework. Discussion is here https://github.com/playframework/twirl/issues/33

You can use like this:

@if(something) {
  ...
} else if (somethingElse) {
  ...
} else {
  ...
}

Answer 5

I used an @ before the second if :

@if (true) {
...
} else { @if (true) {
...
} else {
...
}}

Answer 6

You can use switch statement in Scala to achieve it.
Example:

if(x>2){
   <block 1>

} else if(x>0) {
   <block 2>

} else {
   <block 3>
}

Translated:

x match {
   case x if(x>2) => {<block 1>}
   case x if(x>0) => {<block 2>}
   case _ => {<block 3>}
}

Hope can help you in some cases and hope play framework will support else if soon.
