数组对象的命名问题 [英] Naming problem on array object
问题描述
我有一个数组来存储一些学生信息，例如
var s = new Array（''2006001''，''Apple Joker''，''5B''）;
通常情况下，我们使用s [0]，s [1]，s [2]得到数据......
如何定义它们更具可读性
s [''studentID'']，s [''studentName'']，s [''class'']？
谢谢
I have a array to store some student information, eg
var s = new Array(''2006001'', ''Apple Joker'', ''5B'');
normally, We get the data using s[0], s[1],s[2] ...
How can I define them more readable like
s[''studentID''], s[''studentName''], s[''class''] ?
Thank you

创建一个Object而不是一个数组。
对象的行为类似于/是哈希。
例如：
var myClass = new Object（）;
myClass [" studentID"] = 123;
myClass [" ; studentName"] =" Cyclix";
等
问候，

Make an Object of it instead of an array.
Objects behave like / are hashes.
eg:
var myClass = new Object();
myClass["studentID"] = 123;
myClass["studentName"] = "Cyclix";
etc.

myClass["studentName"] = "Cyclix";
首先感谢您的建议，
这样，
我还能使用myClass [0 ]，myClass [1]得到的值？
Thank you for your suggestion first,
Under this way,
Can I still using myClass[0], myClass[1] to get the value?

首先感谢您的建议，

我还可以使用myClass [0 ]，myClass [1]得到的价值？

No.
对象属性只能有一个名称，即一个字符串。你可以将b $ b称为'0''，'1''，''2'等等，但是你可以使用数组。
您应该查看有关如何使用
方括号和点符号访问属性的常见问题解答：

No.
Object properties can only have one name, which is a string. You can
call them ''0'', ''1'', ''2'', etc. but then you might as well use an Array.
You should probably check the FAQ on how to access properties using
square brackets and dot notation:
