Adding if/then to script include?

[JP-ODU]

I use the following script include to return only room options (u_university_rooms table) that match the selected building code ("u_bldgcode")

var getRooms = Class.create();
getRooms.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    initialize: function() {},
    rooms: function(building) {
        var rooms = [];
        var gr = new GlideRecord('u_university_rooms');

        gr.addQuery('u_bldgcode', building);
        gr.query();
        while (gr.next()) {
            rooms.push(gr.sys_id.toString());
        }
        return "sys_idIN" + rooms.toString();
    },

    type: 'getRooms'
});

I'd like to add the requirement that the options from u_university_rooms *also* be u_active = True

My attempt, below (add "if(u_active="true")/return;"), isn't working:

var getRooms = Class.create();
getRooms.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    initialize: function() {},
    rooms: function(building) {
        var rooms = [];
        var gr = new GlideRecord('u_university_rooms');

        if(u_active="true")
                return;

        gr.addQuery('u_bldgcode', building);
        gr.query();
        while (gr.next()) {
            rooms.push(gr.sys_id.toString());
        }
        return "sys_idIN" + rooms.toString();
    },

    type: 'getRooms'
});

What am I missing? 

Thanks!

Try below

var getRooms = Class.create();
getRooms.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    initialize: function() {},
    rooms: function(building) {
        var rooms = [];
        var gr = new GlideRecord('u_university_rooms');
        gr.addQuery('u_active', true);
        gr.addQuery('u_bldgcode', building);
        gr.query();
        while (gr.next()) {
            rooms.push(gr.sys_id.toString());
        }
        return "sys_idIN" + rooms.toString();
    },

    type: 'getRooms'
});
