AddEventListener到按钮的问题
我正在创建一个简单的随机用户应用程序,每次点击按钮时,它都会显示新的用户信息,我的下一个按钮不起作用,我不知道我在做什么错即将在DOM加载之前按钮。
const apiUrl = `https://randomuser.me/api`;
const nextBtn = document.querySelector('button');
async function getUser(){
const res = await fetch(apiUrl);
const data = await res.json();
console.log(data.results[0]);
let results = data.results[0];
displayUser(results)
}
function displayUser(results){
const userContainer = document.createElement('div');
userContainer.classList.add('user-container');
userContainer.innerHTML = `
<img src="${results.picture.large}" alt="">
<div class="title">
<h3>${results.name.first}</h3>
<h3>${results.name.last}</h3>
</div>
<div class="info">
<h3>${results.location.street.number + ' ' +results.location.street.name}</h3>
<h3>${results.phone}</h3>
<h3>${results.email}</h3>
</div>
<button>Next User</button>
`;
document.body.appendChild(userContainer);
}
getUser();
nextBtn.addEventListener('click', getUser);
I am creating a simple random user app that every time that the button is clicked, it will show the new user information, my next button doesn't work, i have no idea what i am doing wrong but i think I'm calling the button even before The DOM loads.
const apiUrl = `https://randomuser.me/api`;
const nextBtn = document.querySelector('button');
async function getUser(){
const res = await fetch(apiUrl);
const data = await res.json();
console.log(data.results[0]);
let results = data.results[0];
displayUser(results)
}
function displayUser(results){
const userContainer = document.createElement('div');
userContainer.classList.add('user-container');
userContainer.innerHTML = `
<img src="${results.picture.large}" alt="">
<div class="title">
<h3>${results.name.first}</h3>
<h3>${results.name.last}</h3>
</div>
<div class="info">
<h3>${results.location.street.number + ' ' +results.location.street.name}</h3>
<h3>${results.phone}</h3>
<h3>${results.email}</h3>
</div>
<button>Next User</button>
`;
document.body.appendChild(userContainer);
}
getUser();
nextBtn.addEventListener('click', getUser);

创建按钮时,您需要将事件绑定到按钮。该代码不会继续寻找要添加的按钮并将事件添加到其中。
You need to bind the event to the button when you create the button. The code does not keep looking for buttons to be added and add events to it.
