JS Projects
I completed the reviews project on John Smilga's Vanilla JS Walkthrough projects on youtube https://www.youtube.com/watch?v=3PHXvlpOkf4 Here is the JS code in the app.js:
// local reviews data
const reviews = [
{
id: 1,
name: "susan smith",
job: "web developer",

},
];
// select items
const img = document.getElementById("person-img");
const author = document.getElementById("author");
const job = document.getElementById("job");
const info = document.getElementById("info");
const prevBtn = document.querySelector(".prev-btn");
const nextBtn = document.querySelector(".next-btn");
const randomBtn = document.querySelector(".random-btn");
//set starting item
let currentItem = 0;
// load initial item
window.addEventListener("DOMContentLoaded", function (){
showPerson(currentItem)
});
// show person based on item
function showPerson(person) {
const item = reviews[person];
img.src = item.img;
author.textContent = item.name;
job.textContent = item.job;
info.textContent = item.text;
}
// show next person
nextBtn.addEventListener("click", function (){
currentItem++;
if (currentItem > reviews.length - 1){
currentItem = 0;
}
showPerson(currentItem)
});
// show prev person
prevBtn.addEventListener("click", function (){
currentItem--;
if (currentItem < 0){
currentItem = reviews.length -1;
}
showPerson(currentItem)
});
// random number generator
function randNum() {
return Math.floor(Math.random()*(reviews.length))
;}
// show random person
randomBtn.addEventListener("click", function(){
currentItem = randNum();
showPerson(currentItem)
});
Takeaway Learning
- After having quite a break from coding this was good to get things booted up again.
- It felt pretty straight forward in terms of the js side. Using window.addEventListener("DOMContentLoaded", function (){ showPerson(currentItem) was new. MDN Docs... "The DOMContentLoaded event fires when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading."
