模板中的java play框架访问HashMap

Question

I have a tag like this

   public class AcsTag {


         public static String getStyles(String paramter) {
             return hashMap<String, String>()

             }

         }
     }

I can access this tag in template (scala.html) like this

 @import com.twago.fms.shared.ui.AcsTag


 @AcsTag.getStyles(paramter)

getStyles method return a HasMap, I want to store that hashMap in a variable and then later get value from this hash map by key. I do want to iterate over map . I specifically want to access values by key.

following code i tried but always give error

"map not defined"

  map =@{AcsTag.getStyles(paratmeter))}
  @{map.get("themeColor")}

error "map not defined"

To declare a variable, you have to set at the top of your template:

@yourValue = @{yourExpression}

So, to declare a map value, you should do:

@map = @{AcsTag.getStyles(parameter)}

Then you'll be able to use yout map value anywhere in your template. Eg:

<div class="@map.get("themeColor")">...</div>
