blocks|key|3633608|text|"Student1“不是对象的名称(对象没有名称)，而是引用该对象的变量的名称。您不能从对象中获取该名称，尤其是因为同一个对象可以有多个指向它的变量：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3633609|var+Student1+=+new+Student("David",+"FD201F",+"12345678");

&quot;Student1&quot; isn't the object's name (objects don't have names), it's the name of the the variable that refers to the object. You can't get that name from the object, not least because the same object can have more than one variable pointing at it:
<pre><code>var Student1 = new Student(&quot;David&quot;, &quot;FD201F&quot;, &quot;12345678&quot;);
var Student2 = Student1; // Both now point to the same object
</code></pre>
In general, there's no reason to try to get the name of the variable. Instead, store any relevant information you need about the object on the object itself, or if you need to associate objects with names outside the object, use a <code>Map</code> or an object with a property (which has a name) that refers to the object.

blocks|key|2219971|text|我无法想象您为什么需要它，因为名称只是开发人员访问值的引用。你可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2219972|var+students+=+{};

I can't imagine why you could need this, because names are just references for the developer to access values..
You could do this instead:
<pre><code>var students = {};
students['student1'] = new Student(&quot;David&quot;, &quot;FD201F&quot;, &quot;12345678&quot;);
students['student2'] = new Student(&quot;Joe&quot;, &quot;FFFFFF&quot;, &quot;87654321&quot;);
</code></pre>
then you can access to students keys like this:
<pre><code>Object.keys(students).forEach(key =&gt; console.log(key));
</code></pre>

blocks|key|2219984|text|您不能这样做，除非使用一些复杂的东西，例如尝试访问内存和检查与每个对象的实例相关的名称。使用某种类型的反射。但那将是一场噩梦|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2219985|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

you can't do this, unless using some complicated stuff, like trying to access the memory and checking wich name is related to the instance of each object.
using some sort of reflection. but it would be a nightmare

How can I print out the object Name &quot;Student1&quot; ?
Using Student1.constructor.name , I can only get &quot;Student&quot; but not &quot;Student1&quot;
Thank you!
<pre><code>function Student(aName, aCourse, idNumber, noOfQuiz){
 this.name = aName;
 this.courseCode = aCourse;
 this.studentID = idNumber;
 }

var Student1 = new Student(&quot;David&quot;, &quot;FD201F&quot;, &quot;12345678&quot;)
</code></pre>
