简明的方法来比较多个值

问题描述:

请考虑以下事项:

var a = 'jesus';

if(a == 'something' || a == 'nothing' || a=='anything' || a=='everything'){
   alert('Who cares?');
}

有没有办法让它缩短?

Javascript中是否有任何内容,如 if(a =='bbb'||'ccc')

Is there anything in Javascript like if (a=='bbb'||'ccc')?

此外,jQuery可以在这里帮忙吗?

In addition, can jQuery help here?

使用正则表达式:

if (/^(something|nothing|anything|everything)$/.exec('jesus')) alert('Who cares?');​

或相反:

/^(something|nothing|anything|everything)$/.exec('jesus')||alert('Who cares?');​

[更新]更短; - )

[Update] Even shorter ;-)

if (/^(some|no|any|every)thing$/.exec('jesus')) alert('Who cares?');​
