Currently cannot figure out how to add radio buttons to this javascript so it works on them aswell.

I am trying to add radio buttons to the if statement so that they get highlighted when not clicked on aswell

Thanks Much

var emptyFields = [];

var completedFields = [];

for (var i=0; i<this.numFields; i++) {

     var f= this.getField(this.getNthFieldName(i));

     var v= this.getField(this.getNthFieldName(i));      

if (f.type!="button" && f.required ) {

        f.strokeColor = color.black;

        f.fillColor = color.white;

          if ((f.type=="text" && f.value=="") || (f.type=="checkbox" && f.value=="Off") || (v.value==" ")) {

            emptyFields.push(f.name);

            f.strokeColor = color.red;

            f.fillColor = color.white;

  }                

}

}

if (emptyFields.length>0) {

app.alert("Error! You must fill in all required fields (Highlighted in red)");

}
