Play framework: javascripts in scala code?

Question

If I have a html document with this:

 <p onclick="hiho('@name')"> clicky </p>


<script>
    function hiho(namevar){
        var1 = @Names.find.where().eq("name", namevar).findUnique();
        if( var1 != null){
            alert("HIHO");
        }
    }
</script>

How do I use the JavaScript variable?

Play won't compile properly because inside

var1 = @Names.find.where().eq("name", namevar).findUnique();

it cannot find the value of namevar.

Answer 1

One, pretty straightforward, solution could be:

<p onclick="hiho('@name')"> clicky </p>

<script>
    var map = {
        '@name': '@Names.find.where().eq("name", name).findUnique()'
    };

    function hiho(namevar){
        var value = map[namevar];
        if( value != null){
            alert("HIHO: " + value);
        }
    }
</script>

Supposing that the name variables are strings.

You'll probably want to make an AJAX request back to the server. This page talks about that some toward the bottom, and about the routing code you'll need.
