Is it possible to integrate JavaScript into Scala code using Play framework?

Question

Is it possible to integrate JavaScript into Scala code using Play framework?

Suppose I have an HTML document with the following content:

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


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

Is there a way to effectively utilize the JavaScript variable in this scenario?

The Play framework won't compile correctly due to the issue highlighted within:

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

It seems unable to locate the value of namevar at that point.

Here is a simple and effective solution:

<span onclick="greetings('@person')"> Click here </span>

<script>
    var dictionary = {
        '@person': '@PersonList.search().filter('name', name).getFirst()'
    };

    function greetings(personName){
        var result = dictionary[personName];
        if(result !== null){
            alert("Greetings: " + result);
        }
    }
</script>

This solution assumes that the person names are in string format.
