Scala : clever suggestion to build an HTML select option list with Scala

[Nicolas Martignole]

Hi Players

This is a question about Scala.

My customer would like a select/drop-down list on its register page
so that a new visitor can enter its birthdate. The customer will have
to select first the day in a combo-box, then the month and its year...

To generate a select/option with a list of days, I use this template :
It works, but I think it might not be the best solution

            <select name="dobDay" id="dayOfBirth">
               @((1 to 31 toList).map{e=>format.raw("<option value='"+e+"'>" + e +"</option>")})
            </select>

Do you have a better suggestion ?

This does not work
     <select name="dobDay" id="jourNaissance">
               @(1 to 31 toList).map{ e=>
                   <option value="@e">@e</option>
                }
            </select>
(I get a "not found: value e")

Thanks

Answering to myself...

I created a custom tag and it's a bit simplier.
I also implemented the case where the validation failed, the page is
reloaded and we need to select the previous value.

In the main page I declared my tag as shown below :

<select name="dobDay" id="jourNaissance">

@generateOption(31,flash.get("dobDay"))
</select>

In the generateOption.scala.html I wrote this :

@(rangeParam:Int,currentValue:String)
@((1 to rangeParam toList).map{e=>
if(currentValue!=null && e.equals(Integer.parseInt(currentValue)))
{
format.raw("<option selected value='"+e+"'>" + e +"</option>")
} else {

format.raw("<option value='"+e+"'>" + e +"</option>")
}
}
)

Hope it will also help someone with Scala, html select, option and
selected

<select name="dobDay" id="dayOfBirth">

               @Range(1,31).map{e =>

               <option value='@e'>@e</option>)

               }

            </select>

Your problem is the parentheses that will declare all what in between as code and the @ should be followed by a method call.

If you're not going to reuse this template anywhere else you could declare it on the same html using Reusable Blocks

Good idea. The scala template can not parse parentheses correctly which without ident.
