三元表达式当判断为真值不改变应该怎么写更合理

Question

比如:

getCookie("home_voice") ? true : setCookie("home_voice",0);

给true感觉怪怪的,请问有更合适的吗?不知道给空字符串("")可行吗?

Answer 1

getCookie("home_voice") || setCookie("home_voice",0)

Answer 2

空字符串不行，因为用 if 判断，空字符串会返回 false

Answer 3

用or就行了

getCookie("home_voice") || setCookie("home_voice",0);

Answer 4

getCookie("home_voice")？getCookie("home_voice")：setCookie("home_voice",0);

Answer 5

那你为什么还要用三元？楼上正解
若是真执行，则用getCookie("home_voice") && setCookie("home_voice",0)
若非真执行，则用getCookie("home_voice") || setCookie("home_voice",0)
仍要用则
getCookie("home_voice") ? console.log(“getCookie("home_voice")=true”) : setCookie("home_voice",0);
便于调试
