怎么用jquery说'或'？

Question

我有这段代码：

name = afunction('thing1'.trim());

我想要的是修剪thing1或thing2或thing3（以可用的为准）。怎么做？ 我尝试了||，OR和逗号。他们都没有工作。

Answer 1

我认为你可以使用变量：

var item = "thing1" || "thing2"; // or assign with a ternary operation.
name = afunction(item.trim());

Answer 2

|| should work fine

var thing1 = null;
var thing2 = undefined;
var thing3= "Thing 3 ";

alert( (thing1||thing2||thing3).trim());

//Test 2 

thing1 = "";
thing2 = "Thing 2 ";
var thing3= "Thing 3 ";

alert( (thing1||thing2||thing3).trim());
