Unable to access object values outside callback in javascript


Maybe something like this

<html lang="en">
<head>
<meta charset="utf-8">
<script>
 //callback function for jsonp
 function handleEntry (entry) {
console.log(entry);
console.log(entry.results[0]);
console.log(entry.results[0].headword);
document.getElementById("blanks").innerHTML =
entry.results[0].headword;
document.getElementById("definition").innerHTML =
entry.results[0].senses[0].definition;
var myHeadword = entry.results[0].headword;
var toBeUsedForCallBack =
entry.results[0].senses[0].definition; 
ThisIsTheSecondCallBackFunction(toBeUsedForCallBack)
}

console.log(entry.results[0].senses[0].definition);

function loadWord() {
// Get a random number within the range of the
dictionary index and assign it to the variable
randomOffset
var randomOffset = Math.floor(Math.random() *
(21178));
console.log("offset: " + randomOffset);
// Use the variable randomOffset in the API query
URL to get a single random entry
var url =
"https://api.pearson.com/v2/dictionaries/lasde/entries?offset="
+ randomOffset +
"&limit=1&jsonp=handleEntry";
console.log("headword API: " + url);


// Create a new script element
var script_element =
document.createElement('script');
// Set its source to the JSONP API
script_element.src = url;
// Stick the script element in the page
<head>
   
document.getElementsByTagName('head')[0].appendChild(script_element);
ThisIsTheFirstCallBackFunction(url)
}

function ThisIsTheFirstCallBackFunction
(yourFirstParameterHere){ alert('this is your 1st
parameter ' + yourFirstParameterHere);}
function ThisIsTheSecondCallBackFunction
(yourSecondParameterHere){ alert('this is your 2nd
parameter ' + yourSecondParameterHere);}
    </script>
</head>

Related to : Unable to access object values outside callback in javascript
A function that takes a callback and creates a new version of the callback that can only be called once. Javascript
Your function once does not return anything, and your function call does not call anything. Make it function once(func) { var hasActionBeenCalled = false; return function() { if (!hasActionBeenCalled) { hasActionBeenCalled = true; return func.apply(this, arguments); } } } For garbage collection, I'd recommend to do function once(func) {

Call a function within same object as a callback
The 'this' you are trying to use is inside a different function thus 'this' is different. To be able to access the URL property from within the ready check function store the service into a variable to be able to access it later. Like this: var service; service = { get: function(repoName, cb){ this.i[repoName].length > 0 ? cb(this.i[repoName]) : rest[repoName].query(cb) },

Javascript Callback Functions - Node.js
I think your problem is due to the way you pass arguments to your function. download(image, filename,twitterPost(filename)); check in twitterPost(filename) that your filename is as expected. I'm pretty sure it wont. That's because your twitterPost function is not called with this argument. It is called with : request(uri).pipe(fs.createWriteStream(filename)).on('end', callback); that is, no
