Reactで scrollの position/top/位置/value/値 の取得

Last updated at Posted at 2019-01-24

以下の両方でとれる。

<div
	ref={(el)=> console.log($(el).scrollTop()) }
	onScroll={(v)=> {
		// elementが取れる
		console.log(v.target);
	}}
>

注意

console.log(v)

とした時、

targetには null と表記された。

が、実際に console.log(v.target) とすると

elementが出力された。

やばみ。
