**
`
blink()
`
**
は {{jsxref("String")}} 値のメソッドで、この文字列を
`
<blink>
`
の中に埋め込んだ文字列 (
`
<blink>str</blink>
`
) を生成し、古いブラウザーにおいて文字列を点滅させるために使用します。

[
HTML ラッパーメソッド
]
(
/ja/docs/Web/JavaScript/Reference/Global_Objects/String#html_ラッパーメソッド
)
はすべて非推奨となっており、互換性目的のみで標準化されています。
`
blink()
`
の場合、
`
<blink>
`
要素自体が現代のブラウザーから削除されており、テキストを点滅させることは、複数のアクセシビリティ標準で忌避されています。この要素を使用することは避けてください。
##
構文
```
js-nolint
blink()
```
###
引数
なし。
###
返値
`
<blink>
`
開始タグで始まり、
`
str
`
のテキストが来て、
`
</blink>
`
終了タグが来る文字列です。
##
例
###
blink() の使用
以下の例では文字列のメソッドを使用して、文字列の整形方法を変化させています。
```
js
const
contentString
=
"
Hello, world
"
;
document
.
body
.
innerHTML
=
contentString
.
blink
();
```
これにより、次の HTML が生成されます。
```
html
<
blink
>Hello, world</
blink
>
```
>
[
!WARNING
]
>
このマークアップは、
`
blink
`
が有効な要素でなくなったため、不正です。
要素の点滅は完全に避けるべきです。
