JavaScript sorting object

I have a JavaScript object (name, noWords, score, group)

flower - 1 - 88 - 0
flower - 1 - 99 - 0
flower,spring - 2 - 39 - 1
flower,spring - 2 - 58 - 1
flower,time - 2 - 20 - 2
flower,time - 2 - 53 - 2
spring,time - 2 - 55 - 3
flower,spring,time - 3 - 79 - 4
flower,spring,time - 3 - 121 - 4

I want to sort this object like this: first matter the number of words - it's made, then if there are more groups with the same number of words to sort by greater value of each 开发者_StackOverflow社区group

Expected result

flower - 1 - 88 - 0
flower - 1 - 99 - 0
flower,time - 2 - 20 - 2
flower,time - 2 - 53 - 2
spring,time - 2 - 55 - 3
flower,spring - 2 - 39 - 1
flower,spring - 2 - 58 - 1
flower,spring,time - 3 - 79 - 4
flower,spring,time - 3 - 121 - 4

assuming your objects are in an array, you can use a custom sort method for comparing two entries.

var myObjects = [ /* assuming this is filled. */ ];

myObjects.sort(function (a, b) {

    // a and b will be two instances of your object from your list

    // possible return values
    var a1st = -1; // negative value means left item should appear first
    var b1st =  1; // positive value means right item should appear first
    var equal = 0; // zero means objects are equal

    // compare your object's property values and determine their order
    if (b.noWords < a.noWords) {
        return b1st;
    }
    else if (a.noWords < b.noWords) {
        return a1st;
    }

    // noWords must be equal on each object
    if (b.group < a.group) {
        return b1st;
    }
    else if (a.group < b.group) {
        return a1st;
    }

    // group must be equal
    // TODO continue checking until you make a decision

    // no difference between objects
    return equal;
});

Your description of how you want things ordered is unclear so I'll leave that part up to you.

First of all you mean Array. You can't sort an Object.

What you need is to perform an user sort. To do this you use the Array.sort() method along with a custom sorting function. In that function you put you comparison algorithm.

Simple example:

myArray = [5, 3, 7, 9];
myArray.sort(function(a, b){
    if(a > b)
        return -1; // negative means that the elements are not in the right order and should be switched
    else
        return 1; // positive means that the element are in the desired order
});

The sort method does all the sorting for you but you have to provide the means of comparing any two elements.
