url

Any string that specifies the href attribute of the <a> element; it should be a valid URL (relative or absolute), with any & characters escaped as &.

A string beginning with an <a href="url"> start tag (double quotes in url are replaced with "), then the text str, and then an </a> end tag.

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

const contentString = "MDN Web Docs";

document.body.innerHTML = contentString.link("https://developer.mozilla.org/");

This will create the following HTML:

<a href="https://developer.mozilla.org/">MDN Web Docs</a>

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

const contentString = "MDN Web Docs";
const elem = document.createElement("a");
elem.href = "https://developer.mozilla.org/";
elem.innerText = contentString;
document.body.appendChild(elem);

• Polyfill of String.prototype.link in core-js
• HTML wrapper methods
• <a>
