Sorting object in javascript

Question

I have object which also has object as a value. I want to sort that object based on 'copy' key value. fiddle

var x= {'one':{'copy':'b'},'two':{'copy':'v'},'three':{'copy':'a'}}

var getsort= []

for(i in x){
 var a= new Object();
    a[i]=x[i]

    getsort.push(a)
}

getsort.sort(function(a,b){
    //console.log(b)
    //console.log(a.copy)
    var textA = a.copy.toUpperCase();
    var textB = b.copy.toUpperCase();
    return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
})
console.log(getsort)

Have a look at `getsort`. Is this really what you want to create? Do you not actually want `getsort.push(x[i])`? — Felix Kling, Jul 08 '15 at 10:22
After sorting I have to give the result in object format. like the way I am receiving it — Jitender, Jul 08 '15 at 10:24
expected output : x= {'three':{'copy':'a'},'one':{'copy':'b'},'two':{'copy':'v'}} — Jitender, Jul 08 '15 at 10:25
Are you sure you want order in Object ? [Does JavaScript Guarantee Object Property Order?](http://stackoverflow.com/questions/5525795/does-javascript-guarantee-object-property-order) — fuyushimoya, Jul 08 '15 at 10:28
I've created an answer before, but as I realized that you want the `Object` 'key to be ordered, I just delete my answer. — fuyushimoya, Jul 08 '15 at 10:29

This will work for you:

var x= {'one':{'copy':'b'},'two':{'copy':'v'},'three':{'copy':'a'}}

var getsort= []

for(i in x){
    if (i != undefined)
    {

    //console.log(i);
 var a= new Object();
    a[i]=x[i]
    //console.log(a[i]);
    getsort.push(a);
    }
}


function getValue(data)
{
    for(key in data) {
    if(data.hasOwnProperty(key)) {
        var value = data[key];
        return value;
    }
}
}

getsort.sort(function(a,b){
    console.log(getValue(b).copy)
    console.log(getValue(a).copy)
    var textA = getValue(a).copy.toUpperCase();
    var textB = getValue(b).copy.toUpperCase();
    return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
})
console.log(getsort);

No, properties order in objects are not guaranteed in JavaScript, you need to use an Array.

But to make an array you don't need to copy to another object in the loop

  var x= {'one':{'copy':'b'},'two':{'copy':'v'},'three':{'copy':'a'}}

    var getsort= [];

    for (i in x) {  
        getsort.push(x[i])
    }

    getsort.sort(function(a,b){

        var textA = a.copy.toUpperCase();
        var textB = b.copy.toUpperCase();

        return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;

    })
    console.log(getsort)

See what the OP wants. He want a `Object`. not `Array`. – fuyushimoya Jul 08 '15 at 10:29
