fonction avec callback js code example
Example 1: javascript getposts callback
// *** JS GetPosts Callback ***
run.addEventListener('click', () => {
window.lib.getPosts((error, articles) => {
return (error ? console.log(error) : console.log(articles));
/* Alternate syntax
if (error) {
console.log(error);
}
for (elem of articles) {
console.log(elem);
}; // => console.log(articles); similarly works
/*
});
})
Example 2: javascript callback
// Create a callback in the probs, in this case we call it 'callback'
function newCallback(callback) {
callback('This can be any value you want to return')
}
// Do something with callback (in this case, we console log it)
function actionAferCallback (callbackData) {
console.log(callbackData)
}
// Function that asks for a callback from the newCallback function, then parses the value to actionAferCallback
function requestCallback() {
newCallback(actionAferCallback)
}
