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);?
