How to render JSON in Rails with JS function in field? -

i want give response server this:

{foo: "some value", bar: function(){console.log(this);}} 

but if write response line in controller so:

render json: {foo: "some value", bar: 'function(){console.log(this);}'} 

the result follows:

{foo: "some value", bar:"function(){console.log(this);}"} 

don't use eval — it's unsafe , tricky. wrap function body quotes, remove keyword function out of there , create new function on clientside function constructor.

json:

{     "fn": "alert(arguments);" } 

clientside parsing code:

var myfunction = new function(json.parse(jsonstring).fn); 

this better because function won't automatically execute code or expose global context.

the considerable inconvinience absence of arguments list. have use arguments object instead.
