sending javascript object with key : function pair in jade template

Question

sending javascript object with key : function pair in jade template

i am rendering a jade file as :

On server side :

var html = jade.renderFile('ui/index.jade', {
    printHello : function(){
       console.log('Hello World');
    }
});

On client side in index.jade :

script(type="text/javascript").
      var s = #{JSON.stringify(patternMatch)};
      s.printHello(); //Desired to print 'Hello world' on browser console

But s.printHello() says Object Object does not have function 'printHello';

and console.log(s); // gives {} 'empty object';

Why is that so.?

And how do i make printHello present and work?

javascript
node.js
jade

Answer 1

this is what i did. i send the stringed code from server

var html = jade.renderFile('ui/index.jade', {
    printHello : "("+"function(){ console.log('Hello World'); }"+")"
});

Then on client side

script(type="text/javascript").
      var s = !{JSON.stringify(patternMatch)};
      var myFunc = eval(s['printHello'])
      console.log(myFunc()); //prints "Hello World" on client browser
