A common practice is returning data in the JSON format by a server. Let a server have the following file:
{
"num1": "1",
"num2": "2"
}
Let's obtain data from this file:
button.addEventListener('click', function() {
fetch('/data.json').then(response => {
return response.text();
}).then(data => {
console.log(JSON.parse(data));
});
});
You can use the json
method
to automatically convert JSON to
a JavaScript structure:
button.addEventListener('click', function() {
fetch('/data.json').then(response => {
return response.json();
}).then(data => {
console.log(data);
});
});
Let a server return an array in
JSON. Loop through this array
and write each element in a
separate li
.
