Error: The data from the intermediate value cannot be parsed using the parseFromString() method and replaced with another value,

I'm working on a project where I need to display parsed HTML content within an element. However, before displaying it, I need to make some changes to the HTML using the `replace` method. But unfortunately, I encountered a TypeError: (intermediate value).parseFromString(...).replace is not a function issue. Can anyone provide assistance in resolving this problem? Thank you.

const parsedHTML = new DOMParser().parseFromString(html, "text/html");
const renderHtml = parsedHTML.replace('aria-expanded="false"', 'aria-expanded="true"');
console.log(renderHtml);

Answer №1

Trying to use a DOMParser object as a string will not yield the desired results.

In order to achieve the desired outcome, it is recommended to follow a process like the one outlined below:

const html = `<html><div aria-expanded="false"></div></html>`
const parsedHTML = new DOMParser().parseFromString(html, "text/html");
parsedHTML.querySelector("div").setAttribute("aria-expanded",true)
console.log(parsedHTML.querySelector("div"));
