if语句中多个OR表达式的简写 [英] Shorthand for multiple OR expressions in if statement

问题描述

是否有以下简写 -

Is there a shorthand for the following -

if(tld == "com" || tld == "net" || tld == "co" || tld == "org" || tld == "info" || tld == "biz")
{
    //do something;
}

推荐答案

你可以使用数组

if(["","com","net","co","org","info","biz"].indexOf(tld) > -1) {
     // do something
}

或者如果您使用的是jquery：

or if you are using jquery :

$.inArray(tld, ["com","net","co","org","info","biz"])

REF -
OR操作（||）与inArray（）的性能
