I really struggling with this.
I need to basically make it so whatever is written in a newly created textbox is stored in local storage.
// TODO: Q1(c)(iii)
// Make an event listener to save text when it changes:
// ...get the textarea element's current value
// ...make a text item using the value
// ...store the item in local storage using the given key
// Connect the event listener to the textarea element
var item, data, key;
var textareaElement = document.createElement("TEXTAREA");
textareaElement.addEventListener("change", function(event) {
var myText = document.getElementById("textareaElement").value;
localStorage.setItem("text", myText);
item = makeItem ("text", myText);
});

Reset to default 1var item, data, key;
var textareaElement = document.createElement("TEXTAREA");
document.body.appendChild(textareaElement); //Add the element to the document
textareaElement.addEventListener("change", function(event) {
var mytext = textareaElement.value; //You already have the element as a variable
localStorage.setItem("text", myText);
item = makeItem("text", myText);
});
function makeItem() { //Don't forget to define makeItem
//code
}
Create an input like this in your HTML
<textarea id=‘textarea’ onchange=‘save()’ />
In JS:
const textarea = document.querySelector(‘#textarea’)
function save() {
localStorage.setItem("text", textarea.value);
}
