Sorting JavaScript Object by property value

自2006年以来我已经注意到,浏览器可以保证发出“JSON trough anjax”电话(参赛人/参赛人 )的顺序,我感到有些麻烦的是,在接到“jax”电话后将JSON元素与javascript混在一起。

I ve found some topics about this issue, but nothing gave me a clear solution for the simple structure of my JSON object. I just got 1 segment with a lot of data. I know there are a lot of topics about this, even on stackoverflow, but no topic handles this simple json structure.

例如:

{
   "158":"Banana",
   "265":"Pear",
   "358":"Apple",
   "864":"Peach"
}

How can I sort this object on the fruitnames instead of the id s? I d like to have this object at the end:

{
   "358":"Apple",
   "158":"Banana",
   "864":"Peach"
   "265":"Pear",
}

提前感谢。

Answer 1

var kk = {
   "158":"Banana",
   "265":"Pear",
   "358":"Apple",
   "864":"Peach"
}

var keys = [];
var datas = {}

$.each(kk, function(key, value){

  keys.push(value)
  datas[value] = key;

})
    var aa = keys.sort()

        var sorted ={}

$.each(aa, function(index, value){

    sorted[datas[value]] = value;
})

Answer 2

var someObject = {
   "158":"Banana",
   "265":"Pear",
   "358":"Apple",
   "864":"Peach"
};

//flip the name/value pairs
Object.prototype["reverseObject"] = function() {
    var name;
    var newObject = {};
    for(name in this) {
        if(typeof this[name] !==  function ) {
           newObject[this[name]] = name;
        }
    }
    return newObject;
}

var reversedObject = someObject.reverseObject();

console.log(reversedObject);

var i;
var properties = [];
//get all the property names
$.each(reversedObject, function(key, value) {
    if(reversedObject[key] !== this)
    properties.push(key);
});

properties.sort();

var sortedObject = [];

//iterate the array using the order specified
for(i = 0; i < properties.length; i += 1) {
    sortedObject[properties[i]] = reversedObject[properties[i]];
    //document.writeln(properties[i] + " : " + reversedObject[properties[i]]);
}

var sortedObject = sortedObject.reverseObject();

console.log(sortedObject);

这就产生了按字母顺序排列的一系列财产名称。然后,这种阵列被用来对目标进行索引。这导致你要求的确切目标。
