在上述示例中,需要将'url/to/json/data'替换为实际的JSON数据的URL。fetch函数会发送一个GET请求到该URL,并返回一个包含响应数据的Promise对象。然后,使用response.json()方法将响应数据解析为JSON对象,并返回一个Promise对象。最后,使用then方法处理解析后的JSON对象。
.then(response => response.json()) .then(data => { console.log(data); return data; }) .catch(error => console.error(error)); } //let data = new Map(Object.entries(fetchData())) const data = fetchData() let map1 = new Map() for(let i=0;i<30;i++) { map1.set(data[i...

Generating URLs The other way to get data from the server to JavaScript is to make a request for it. First, you need to know the URL to request. The simplest way to generate URLs is to continue to use url_for() when rendering the template. For example: const user_url = {{ url_...
fetch('ajaxfile.php?request=fetchrecordbyid', options) .then(response => { if (!response.ok) { throw new Error('Network response was not ok'); } return response.json(); }) .then(data => { // Append data to const emptable = document.getElementById('employeesTable').querySelector...
