Problems with array.Sort()

Question

I’m trying to sort an array but I’m having trouble, it’s only returning 0. I’m doing the following:

Here I draw my array:

arrayVelho.sort(compare);

After I call the compare function which compares the array data:

function compare(a,b) {

//return a.TXT_NOMEX_PESSO < b.TXT_NOMEX_PESSO;
var valorA = ((a.TXT_NOMEX_PESSO == null)? "Z": a.TXT_NOMEX_PESSO),
    valorB = ((b.TXT_NOMEX_PESSO == null)? "Z": b.TXT_NOMEX_PESSO);

var respA = valorA.toUpperCase(),
    respB = valorB.toUpperCase();

        console.log(respA + " - " + respB);
    console.log(respA.TXT_NOMEX_PESSO > respB.TXT_NOMEX_PESSO ? -1 : respA.TXT_NOMEX_PESSO < respB.TXT_NOMEX_PESSO ? 1 : 0);
    return respA.TXT_NOMEX_PESSO > respB.TXT_NOMEX_PESSO ? -1 : respA.TXT_NOMEX_PESSO < respB.TXT_NOMEX_PESSO ? 1 : 0;
}

The result of console.log() looks like this:

HADAILTON DE SOUSA CARVALHO - RENAN RODRIGUES MORAES main.js:1350
0 main.js:1351
RENAN RODRIGUES MORAES - TESTESS main.js:1350
0 main.js:1351
TESTESS - ANTONIO main.js:1350
0 main.js:1351
ANTONIO - BACHINHO main.js:1350
0 main.js:1351
BACHINHO - CASA DE CARNE main.js:1350
0 

The structure of my array is:

arrayVelho[Object, Object, Object, Object, Object, Object]

0: Object
COD_IDENT_PESSO: "3"
FLG_IDENT_PESSO: "L"
FLG_STATU_PESSO: "A"
TXT_NOMEX_PESSO: "HADAILTON DE SOUSA CARVALHO"
---------------
1: Object
COD_IDENT_PESSO: "4"
FLG_IDENT_PESSO: "M"
FLG_STATU_PESSO: "A"
TXT_NOMEX_PESSO: "RENAN RODRIGUES MORAES"
---------------
2: Object
COD_IDENT_PESSO: "3160127100149523"
FLG_IDENT_PESSO: "M"

4: Object
COD_IDENT_PESSO: "3160127100908469"
FLG_IDENT_PESSO: "M"

5: Object
COD_IDENT_PESSO: "3160127100924955"
FLG_IDENT_PESSO: "M"
FLG_STATU_PESSO: "A"
TXT_NOMEX_PESSO: "casa de carne"

It should be ordered Alphabetically, I have no way to predict, because this array is of all people, it can have 5 people as it can have 20.

What am I doing wrong? And how to put in Alphabetical order ?

Answer 1

It cannot order correctly when it has uppercase and lowercase values.

Then you just use the function toUpperCase()to put all the text in Maiúsculo and compare, or if you want to use toLowerCase()that makes the entire text Minúsculo. This question follows the line of reasoning of that answer just by adapting. See:

var array = [ 
    {TXT_NOMEX_PESSO: 'HADAILTON DE SOUSA CARVALHO'},
    {TXT_NOMEX_PESSO: 'RENAN RODRIGUES MORAES'},
    {TXT_NOMEX_PESSO: 'testess'},
    {TXT_NOMEX_PESSO: 'Antonio'},
    {TXT_NOMEX_PESSO: 'bachinho'},
    {TXT_NOMEX_PESSO: 'casa de carne'}
];
 			
function compare(a,b) {
  return a.TXT_NOMEX_PESSO.toUpperCase() > b.TXT_NOMEX_PESSO.toUpperCase();
}

console.log(array.sort(compare));
