Topic: Change element's content and attributes
We use the HTML page of the previous page for the exercises.
1. Modify the function show in a way that it disables the button. Its text shall change to "I'm disabled". Hint:
To disable a button, its attribute disabled must be set to true.
100% function show() {
"use strict";
const elem = document.getElementById("buttonShow");
elem.disabled = true;
elem.innerHTML = "I'm disabled";
}
2. Modify the function show in a way that it opens the link in a new window: target="_blank".
100% function show() {
"use strict";
const elem = document.getElementById("refToSomewhere");
elem.target = "_blank";
}
