String.prototype.fixed()

Deprecated

Avoid using this feature in new projects. HTML wrapper methods exist only for backwards compatibility. Use DOM APIs to create elements instead. This feature may be a candidate for removal from web standards or browsers.

Consider using the following features instead: DOM.

The fixed() method of String values creates a string that embeds this string in a <tt> element (<tt>str</tt>), which causes this string to be displayed in a fixed-width font.

Note: All HTML wrapper methods are deprecated and only standardized for compatibility purposes. For the case of fixed(), the <tt> element itself has been removed from the HTML specification and shouldn't be used anymore. Web developers should use CSS properties instead.

In this article

Syntax

js
fixed()

Parameters

None.

Return value

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

Examples

Using fixed()

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

js
const contentString = "Hello, world";

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

This will create the following HTML:

html
<tt>Hello, world</tt>

Warning: This markup is invalid, because tt is no longer a valid element.

Instead of using fixed() and creating HTML text directly, you should use CSS to manipulate fonts. For example, you can manipulate font-family through the element.style attribute:

js
document.getElementById("yourElemId").style.fontFamily = "monospace";
