String.prototype.strike()

{{Deprecated_Header}}

The strike() method of {{jsxref("String")}} values creates a string that embeds this string in a {{HTMLElement("strike")}} element (<strike>str</strike>), which causes this string to be displayed as struck-out text.

[!NOTE] All HTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case of strike(), the <strike> element itself has been removed from the HTML specification and shouldn't be used anymore. Web developers should use the {{HTMLElement("del")}} for deleted content or the {{HTMLElement("s")}} for content that is no longer accurate or no longer relevant instead.

Syntax#

strike()

Parameters#

None.

Return value#

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

Examples#

Using strike()#

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

const contentString = "Hello, world";

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

This will create the following HTML:

<strike>Hello, world</strike>

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

Instead of using strike() and creating HTML text directly, you should use DOM APIs such as document.createElement(). For example:

const contentString = "Hello, world";
const elem = document.createElement("s");
elem.innerText = contentString;
document.body.appendChild(elem);
