I want to change this paragraph through javascript

Question

document.querySelector("#myBtn").onclick = function () {
  console.log("Clicked");
  const h1 = document.querySelector("#myH1");
  const underline = document.createElement("u");
  underline.innerText = "Hey bro.";
  h1.innerText = "";
  h1.append(underline);

  const p = document.querySelector(".myP");
  p.forEach((element) => (element.innerText = "Thank You!!!!"));

  const btn = document.querySelector("button");
  btn.remove();
};

p.forEach((element) => (element.innerText = "Thank You!"));

I got: Error TypeError p.forEach is not a function

`querySelector` returns an HTML Element not an array like structure... — decpk, Nov 20 '21 at 15:52
Do you mean to use `querySelectorAll`? `querySelector` only returns the first matching node (if present), and not a node list. — Terry, Nov 20 '21 at 15:53

querySelector returns just 1 element. Use querySelectorAll to return a list of elements matching the given selector.

The Document method querySelector() returns the first Element within the document that matches the specified selector.

You could use the getElementsByClassName instead

var p = document.getElementsByClassName('myP"');
for (let i = 0; i < p.length; i++){
  p[i].innerText = "Thank You!!!!";
}

First , Check you createated a query or not.Then variable p is not defined inside the function.use query selector all for return all the elements in the query.

querySelector returns an array that you can iterate with forEach. so you just need to change querySelector to querySelectorAll.

  const p = document.querySelectorAll('.myP')
  p.forEach((element) => (element.innerText = "Thank You!!!!"));
