jquery - variable nth-child?

提问by Hyman

Hey. I want to pass a variable as an argument into an nth-child selector.
This doesn't work:

嘿。我想将一个变量作为参数传递给第 n 个子选择器。
这不起作用:

var position = 5;

$("#daddy > div:nth-child(position)").animate({
    opacity: 0.01,
}, 500);?

Is it possible though? Cheers, Hyman

有可能吗?干杯,Hyman

You need quoting:

你需要引用:

var position = 5;

$("#daddy > div:nth-child(" + position + ")").animate({
   opacity: 0.01,
}, 500);?
