To print all the paths in a json object

Question

What is the easy way to get all paths in the Given Json Object; For Example:

{  
   app:{  
      profiles:'default'
   },
   application:{  
      name:'Master Service',
      id:'server-master'
   },
   server:{  
      protocol:'http',
      host:'localhost',
      port:8098,
      context:null
   }
}

I should able to produce the following object

app.profiles=default
application.name=Master Service
application.id=server-master

I was able to achieve the same using a recursive function. I want to know is there any built in function from json which does this.

You can implement your custom converter by iterating through objects recursively.

Something like this:

var YsakON = { // YsakObjectNotation
  stringify: function(o, prefix) {          
    prefix = prefix || 'root';
    
    switch (typeof o)
    {
      case 'object':
        if (Array.isArray(o))
          return prefix + '=' + JSON.stringify(o) + '\n';
        
        var output = ""; 
        for (var k in o)
        {
          if (o.hasOwnProperty(k)) 
            output += this.stringify(o[k], prefix + '.' + k);
        }
        return output;
      case 'function':
        return "";
      default:
        return prefix + '=' + o + '\n';
    }   
  }
};

var o = {
	a: 1,
  b: true,
  c: {
    d: [1, 2, 3]
  },
  calc: 1+2+3,
  f: function(x) { // ignored
    
  }
};

document.body.innerText = YsakON.stringify(o, 'o');

That's not a best converter implementation, just a fast-written example, but it should help you to understand the main principle.

Here is the working JSFiddle demo.
