Question

If I pass a boolean value to the view, for example “checked”, how to show the different html elements according to the checked value(that is , true or false) ?

#{if ${checked}}
     <p>aaa</p>
#{/if}
#{else}
     <p>bbb</p>
#{/else}

I try the above code but failed…

Answer 1

#{if checked}
     <p>aaa</p>
#{/if}
#{else}
     <p>bbb</p>
#{/else}

The ${} syntax, is only for printing values into your template. Inside the #{if } tag, playframework expects groovy syntax.

Also, check out the documentation for the #{if} tag.
