如何在单击按钮时从 API 获取数据 - Javascript?
How to fetch data from API on button click - Javascript?
我有这部分代码:
fetch(`https/someapi.com/data`)
.then(response => {
return response.json()
}).then(randomProduct => {
document.querySelector('#list').innerHTML = `
<span>${randomProduct.value}</span>
<button id="refresh-button" type="button">Refresh</button>
`;
var clickOnButton = document.querySelector("#refresh-button");
clickOnButton.addEventListener("click", () => {
})
})
如何让这个 onClick 事件刷新我从 API 读取的数据并显示一个新数据?
我不确定我是否正确理解了您的问题,但据我所知,您只想编辑获取时的数据,无需每次都创建按钮和侦听器。将提取放在一个专用函数中,该函数称为提取中按钮的 onClick,只需编辑值即可。
你可以把它全部包装在一个函数中,然后像这样调用它
const fakeApi = () => new Promise(resolve => setTimeout(() => resolve({
value: Math.floor(Math.random() * 100)
}), 500))
const getData = () => fakeApi().then(randomProduct => {
document.querySelector('#main').innerHTML = `
<span>${randomProduct.value}</span>
<button id="refresh-button" type="button" onclick="getData()">Refresh</button>`
})
getData()
<div id="main"></div>
首先你需要一个按钮来发出获取请求
const fetchDataBtn = document.querySelector('#fetchdata')
const result = document.querySelector('#result')
// gets data from API and sets the content of #result div
const getData = function() {
result.innerText = 'Loading....'
fetch('https://dummyjson.com/products')
.then(res => res.json())
.then(data => {
result.innerText = JSON.stringify(data, null, 2)
})
.catch(error => console.log(error))
}
// add event listener for #fetchdata button
fetchDataBtn.addEventListener('click', getData)
const fetchDataBtn = document.querySelector('#fetchdata')
const result = document.querySelector('#result')
// gets data from API and sets the content of #result div
const getData = function() {
result.innerText = 'Loading....'
fetch('https://dummyjson.com/products')
.then(res => res.json())
.then(data => {
result.innerText = JSON.stringify(data, null, 2)
})
.catch(error => console.log(error))
}
// add event listener for #fetchdata button
fetchDataBtn.addEventListener('click', getData)
<button id="fetchdata">FETCH</button>
<div id="result"></div>
