读取并循环遍历具有非唯一键值对的对象 [英] Read and loop through an object with non-unique key value pairs

问题描述

我有一个包含一些键/值对的对象.当有一个键/值对与另一个键/值对共享相同的键时，我在控制台记录对象时无法识别第一个.

I have an object which contains some key/value pairs. When there is a key/value pair that shares the same key as another key/value pair, the first one is not recognised when I console log the object.

例如:

var test = {
"same" : 'Value1',
"same" : 'Value2',
"different" : 'Value3'
};
console.log(test);

在控制台中的结果为:

Object { same="Value2", different="Value3"}

是否无法读取具有相似键名的对象?

Is it not possible to read an object that has similar key names?

我正在尝试使用此方法遍历对象 (如何遍历或枚举 JavaScript对象?)但我只能检索一个共享一个键的键/值对.

I am trying to loop through the object using this method (How do I loop through or enumerate a JavaScript object?) but I can only ever retrieve one the key/value pairs that share a key.

推荐答案

如果需要，您可以更改 JSON 的结构吗?JSON 对象不能有重复的键.把它想象成一个哈希图或字典.根据语言和 JSON 解析器的不同，您也可能会遇到异常(尽管不是在 Javascript 中)

Could you change the structure of the JSON if needed? JSON objects cannot have duplicate keys. Think of it as a hashmap or dictionary. Depending on the language and JSON parser you may also get an exception (not in Javascript though)

在上面的示例中，要么更改它，以便您拥有唯一键，要么将 ti 更改为一组值，例如:

In your example above either change it so that you have unique keys or change ti to an array of values like:

var test = {
"same" : ['Value1', 'Value2']
"different" : 'Value3'
};
console.log(test);
