带条件的键对象排序

Question

I have the below Object

Object={
   '11': 1.2317655481421725,
   '12': 1.233489927305401,
   '13': 1.2317655481421725,
   '14': 1.233489927305401,
   '15': 1.205620575126925,
   '16': 1.2600762465738233,
   '17': 1.205620575126925,
   '18': 1.2600762465738233,
   '41': 0.8577882967879851,
   '42': 0.8890249774881712,
   '43': 0.8577882967879851,
   '44': 0.8890249774881712,
   '45': 0.8268651773658509,
   '46': 0.8977620865671874,
   '47': 0.8268651773658509,
   '48': 0.8977620865671874
 }

which I need to order by the values according to some conditions

• when the values of the keys are equal, check a flag of each one of the keys that may be either 0 or 1, and sort first the one with flag=1
• in any other case sort all the rest keys by value in descending order

The code I run looks like below

keysSorted = Object.keys(Object).sort(function(a,b){

Flag_b=parseInt(Products[Object.keys(Object)[b-1]]['attribute'])
Flag_a=parseInt(Products[Object.keys(Object)[a-1]]['attribute'])
// console.log('key a',Object.keys(Object)[a-1],'Flag_a ', Flag_a, 'key b',Object.keys(Object)[b-1],'Flag_b', Flag_b)

//case equal utilities
if ((Object[b]===Object[a]) && (user.answer===1)){
    key_a=Object.keys(Object)[a-1]
    key_b=Object.keys(Object)[b-1]
    console.log('true equality','key_b',key_b,'Object[b]',Object[b],'key a',key_a,'Object[a]',Object[a])
    console.log('key a',key_a,'Flag_a ', Flag_a, 'key b',key_b,'Flag_b', Flag_b)
    if (Flag_a===1){
        return -1 
    }       
}
if (Object[b]!==Object[a]){
    return (Object[b]-Object[a])
}

})

The correct sorting would start with the key values 11 and 13, if flag of key 11 is 0 and flag of key 13 is 1, then sort first [13,11 ...]

Answer 1

The only order that objects give their properties is such that you can't change it for the object you've shown, because the order for properties with names consisting entirely of digits (within the range 0 to 2³²-1) is numeric . So it doesn't matter what you do with that object or another object, the property with the name "11" will always come before the property with the name "42" .

Trying to put objects in a particular order is usually poor practice even when it's possible (which it is with property names that don't consist entirely of digits).

Instead, use an array of key / value objects, and sort that.
