从Array

Question

做一个JSON随着JS我得到这个

var monthNames = ['jan', 'fev', 'mar', 'abr', 'mai', 'jun', 'jul', 'ago', 'set', 'out', 'nov', 'dez'];

我这样做是为了获得实际的月格式：

var formatter = new Intl.DateTimeFormat("pt-BR", { month: "short" }), 
month1 = formatter.format(new Date()) ; 
var posicao = monthNames.indexOf(month1); 
var mesesSelecionados = monthNames.slice(posicao, 12); 
var mesesSelecionadosJson = {}; 
var arrayteste=[]; 
    for (i =0 ; i< mesesSelecionados.length; i++){ 
     var teste = mesesSelecionados[i].toString(); 
     mesesSelecionadosJson = JSON.stringify({ Mes : mesesSelecionados[i]}, null ); 

       arrayteste.push(mesesSelecionadosJson); 

       console.log(arrayteste); 
       console.log(mesesSelecionadosJson); 
       }; 

所以我尝试得到这样的： [{Mes:"abr"}, {Mes:"mai"}...]（带所有数值）

任何人都可以帮助我？

Answer 1

您可以将阵列映射为对象：

var monthNames = ['jan', 'fev', 'mar', 'abr', 'mai', 'jun', 'jul', 'ago', 'set', 'out', 'nov', 'dez']; 
 
var objectYouWant = monthNames.map(function(month) { return {Mes: month}; }); 
 
console.log(objectYouWant); 
 
// To convert to json 
 
var jsonYouThinkYouWant = JSON.stringify(objectYouWant); 
 
console.log(jsonYouThinkYouWant); 
 

 
// Object you think you want. 
 
var objectYouThinkIsDifferent = [{Mes:'jan'}, {Mes:'fev'}, {Mes:'mar'}, {Mes:'abr'}, {Mes:'mai'}, {Mes:'jun'}, {Mes:'jul'}, {Mes:'ago'}, {Mes:'set'}, {Mes:'out'}, {Mes:'nov'}, {Mes:'dez'}]; 
 
// Notice that the object is the same as the object my solution provides in the log. 
 
console.log(objectYouThinkIsDifferent);

我做的是这样的： 并得到了我想要的东西过滤器！

var d = new Date(); 
var ds = d.toLocaleString().substring(6,10); 
var formatter = new Intl.DateTimeFormat("pt-BR", { month: "short" }), 
     month1 = formatter.format(new Date()) ; 
var monthNames = ['jan', 'fev', 'mar', 'abr', 'mai', 'jun', 'jul', 'ago', 'set', 'out', 'nov', 'dez']; 
var posicao = monthNames.indexOf(month1); 
var mesesSelecionados = monthNames.slice(posicao, 12); 

app1.field('[Ano]').selectMatch(ds, true); 
app1.field('[Tempo]').selectMatch("Mes", true); 
app1.field('[Compara]').selectMatch("Escala", true); 
app1.field('[messtr]').selectValues(mesesSelecionados, true);
