JS數組無法正常顯示？

Question

這是我試圖編寫一個循環遍歷nums，如果該項目是偶數，它將它添加到evens數組，如果該項目是奇數，它將它添加到賠率數組。

var nums = [1,2,34,54,55,34,32,11,19,17,54,66,13]; 
var evens = []; 
var odds = []; 

var sorter = function() { 
    for (var i = 0; i < nums.length; i++) { 
     if (nums[i]%2 !== 0) { 
      odds.push(i); 
     } 
     else { 
      evens.push(i); 
     } 
    } 
}; 
sorter(); 
console.log(evens); 
console.log(odds);

問題是你正在推動你的迭代器到數組中。你應該這樣做：

var nums = [1,2,34,54,55,34,32,11,19,17,54,66,13]; 
var evens = []; 
var odds = []; 

var sorter = function() { 
    for (var i = 0; i < nums.length; i++) { 
     if (nums[i]%2 !== 0) { 
      odds.push(nums[i]); 
     } 
     else { 
      evens.push(nums[i]); 
     } 
    } 
}; 
sorter(); 
console.log(evens); 
console.log(odds);
