String.prototype.blink()

{{Deprecated_Header}}

The blink() method of {{jsxref("String")}} values creates a string that embeds this string in a <blink> element (<blink>str</blink>), which used to cause a string to blink in old browsers.

[!NOTE] All HTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case of blink(), the <blink> element itself is removed from modern browsers, and blinking text is frowned upon by several accessibility standards. Avoid using the element in any way.

Syntax#

blink()

Parameters#

None.

Return value#

A string beginning with a <blink> start tag, then the text str, and then a </blink> end tag.

Examples#

Using blink()#

The code below creates an HTML string and then replaces the document's body with it:

const contentString = "Hello, world";

document.body.innerHTML = contentString.blink();

This will create the following HTML:

<blink>Hello, world</blink>

[!WARNING] This markup is invalid, because blink is no longer a valid element.

You should avoid blinking elements altogether.
