最小值，返回数组名

Question

数组是这样的：

arr[0] = "value"; 
arr[1] = "value2"; 

，也可以是这样的：

var items = { 
    "dioxanes"  : 0, 
    "shunning"  : 1, 
    "plowed"  : 2, 
    "hoodlumism" : 3, 
    "cull"   : 4, 
    "learnings" : 5, 
    "transmutes" : 6, 
    "cornels"  : 7, 
    "undergrowths" : 8, 
    "hobble"  : 9, 
    "peplumed"  : 10, 
    "fluffily"  : 11, 
    "leadoff"  : 12, 
    "dilemmas"  : 13, 
    "firers"  : 14, 
    "farmworks" : 15, 
    "anterior"  : 16, 
    "flagpole"  : 17 
}; 

现在，这里的值将是％，而且必须被比较，但返回的值应该是最小值数组对象的名称。

正如你所理解的，值可以有两个或更多相同的项目。

Answer 1

items不是数组，它是一个对象。

var items = {"dioxanes": 0, "shunning": 1, "plowed": 2, 
      "hoodlumism": 3, "cull": 4,  "learnings": 5, 
      "transmutes": 6, "cornels": 7, "undergrowths": 8, 
      "hobble": 9,  "peplumed": 10, "fluffily": 11, 
      "leadoff": 12, "dilemmas": 13, "firers": 14, 
      "farmworks": 15, "anterior": 16, "flagpole": 17}; 

var min = null, key_min, key; 

for (key in items) { 
    if (items.hasOwnProperty(key)) { 
    if (min === null || items[key] < min) { 
     min = items[key]; 
　　　　　key_min = key; 
    } 
    } 
} 

console.log("The key holds min value is: " + key_min);
