javascript - Can it be written like this?

Question

$("#team .title" || "#team .title1").css("opacity","1");或者$("#team .title" && "#team .title1").css("opacity",&quot

伊谢尔伦 · Answer

There is an expression inside, "#team .title" || "#team .title1" "#team .title" && "#team .title1"因为字符串恒为真，所以两个分别永远都是$("#team .title") $("#team .title1")

You can’t write like this

曾经蜡笔没有小新 · Answer

"#team .title" || "#team .title1" = true
"#team .title" && "#team .title1" = false

Bold guess, $(true) $("falss") is obviously meaningless. If you don't know, just write some tests. It's really lazy.
