How do I call function from jade client side java scripts

I have two drop down lists in my form. Once user selected value from first list I want to filter second list as per selection and display. For that I am using onchange="showSubCat(); of first select option to get selected value. showSubCat() function is defined in client side js file. How do I get value returned by showSubCat() function in jade template so that I can filter array which is populating second list.

var subcode = showSubCat();

gives error.

Any suggestions? Thank you.

New to Jade myself but as far as I can tell you have two options:

1) create the function in jade itself:

-function sayHi(name){
   - return "hello "+name
-}
p= sayHi('bill')

Which I think muddies up your code a bit.

2) A better option would be to pass in the function from the model

app.get('/', function(req, res){  
    res.render('home', { 
        title: 'Home'
        , fs: { sayHi:function(name){
            return "hello "+name
        }}
    });
});

Then in your jade file you just:

p= fs.sayHi('bill')
