一次多个相等运算符 [英] Multiple equality operators at once

问题描述

这可能是一个愚蠢的问题，但是如何一次比较多个变量?

假设我有3个变量:a，b和c，我需要检查它们是否都相同.当然，a==b && b==c可以工作，但是是否有像a==b==c这样的较短语法(这不起作用)?

This might be a stupid question, but how do I compare multiple variables at once?

Say I have 3 varaibles: a, b and c, and I need to check whether they are all the same. Of course, a==b && b==c works, but is there a shorter syntax like a==b==c (this doesn''t work)?

推荐答案

您可以创建一个函数来接受变量列表并将它们全部与另一个项目进行比较(您可以使用for循环).您将使用如下所示的内容:

You could create a function that takes a list of variables and compares them all to another item (you''d use a for loop). You would use it something like this:

var matchesAll = EqualsAll(b, [a, c, d, e, f, g]);

如果您有很多变量，那只会减少输入的数量.

That only cuts down on how much you have to type if you have a lot of variables though.

没有简短的语法，这就是您得到的全部内容.

No shorter syntax, that is all you get.

尝试...

if (a-a)=(b-c)

try...

if (a-a)=(b-c)
