String.prototype.strike()
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see thecompatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Thestrike() method ofString values creates a string that embeds this string in a<strike> element (<strike>str</strike>), which causes this string to be displayed as struck-out text.
Note:AllHTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case ofstrike(), the<strike> element itself has been removed from the HTML specification and shouldn't be used anymore. Web developers should use the<del> for deleted content or the<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 textstr, 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, becausestrike is no longer a valid element.
Instead of usingstrike() and creating HTML text directly, you should use DOM APIs such asdocument.createElement(). For example:
const contentString = "Hello, world";const elem = document.createElement("s");elem.innerText = contentString;document.body.appendChild(elem);Specifications
