Question

Need some JSON help.
I’m working with JSON similar to this:

{
    GreatGrandfather: {
        GrandFather: {
            Father: [
                {
                    Son: [
                        {
                            Name: "Abu Nazir",
                            Detail: {
                                Class: "3rd Grade"
                            }
                        },
                        {
                            Name: "Dexter",
                            Detail: {
                                Class: "6th Grade"
                            }
                        },
                        {
                            Name: "Rick",
                            Detail: {
                                Class: "11th Grade"
                            }
                        }
                    ]
                },
                {
                    Son: [
                         {
                            Name: "Tom Walker",
                            Detail: {
                                Class: "3rd Grade"
                            }
                        },
                        {
                            Name: "Sgt Bastisa",
                            Detail: {
                                Class: "6th Grade"
                            }
                        },
                        {
                            Name: "The Governer",
                            Detail: {
                                Class: "11th Grade"
                            }
                        }
                    ]
                }
            ]
        }
    }
}

My question is how do I delete the Sons that have the Class value of “3rd Grade”?
So both Abu Nazir and Tom Walker will be deleted and each father will have only 2 sons?

Also, how would I add Sons to both fathers?

{Name: "Stewie",Detail: {Class:"Kindergarden"}}

and

{Name: "Peter",Detail: {Class:"1st Grade"}}

Thanks!

Answer 1

var obj = JSON.parse(jsonstring);
obj.GreatGrandFather.GrandFather.Father.forEach(function(father) {
    var sons = father.Son.filter(function(son) {
        return son.Details.Class != "3rd Grade";
    });
    sons.push({Name: "Stewie",Detail: {Class:"Kindergarden"}});
    sons.push({Name: "Peter",Detail: {Class:1st Grade}});
    father.Son = sons;
});
var newjson = JSON.stringify(obj);

Of course you might do it with loops instead of ES5.1-iterator functions, but I think you get the concept.
