React - dynamically adding a hyperlink (anchor html tag) to a string

Question

Let's say I have a string in React "x {y} z" and I would like to dynamically replace {y} with a hyperlink with target = "ylink" Both y and ylink would be dynamic e.g. there would be an object with the text to replace (y) and the target of the hyperlink (link). Is it possible to do this?

Answer 1

yes it's possible you can do as shown below

const getLink = ({href, name}) => {
    return(
      <a href={href} >{name}</a>
    )
  }

x {getLink({href: "google.com", name:"y"})} z  // your react string goes here

Answer 2

Try creating a custom CustomLink component. Using functional component approach:

const CustomLink = (linkTarget, displayString) => <a href={linkTarget}>{displayString}</a>;

You can additionally add properties to the anchor tag such as e.g. rel, target props (see documentation: https://www.w3schools.com/tags/tag_a.asp). Finally, you can evaluate your requested string, but I rather recommend just use JSX if you want to display it in DOM:

const requestedJSX = <div><span>x {<CustomLink linkTarget='ylink' displayString='y'/>} z</span></div>;

Span is there for whitespace retention - feel free to not use it according to your needs. If you are working with single-page app using routes and different pages / views, a good approach is to choose react-router library and build link systems using the react-router-dom readily available Link component (just import it). I have named the custom anchor tag code above different from "Link" as not to mix with the react-router import name.

Example: note that react-router approach does not work unless you fully set up react-router!

import { Link } from "react-router-dom";
const requestedContent = <div>X <Link to='ylink'>Y</Link> Z</div>;

An example snippet to format a text

const formatText = (text, ...args) => {
  const items = text.split('{}');
  
  args.forEach(
     (arg, index) => items.splice(items.length - args.length + index, 0, arg)
  );
  
  return items.join("");
};


console.log(
    formatText("Hello {} welcome {} test {}", "one", "two", "three")
);
