I tried to use the event.clientX outside of window function. But it says xAxis is not defined. Can have an way to get it? My code below,
window.onclick = function(event) {
let xAxis = event.clientX;
}
alert(xAxis);

So I'm trying to learn about JavaScript and geolocation, but I've run into this, probably simple, problem:
let myLat; // Global
navigator.geolocation.getCurrentPosition((position) => {
myLat = position.coords.latitude;
console.log(myLat); // works
});
console.log(myLat); // undefined
I don't get why I cannot just use a global variable to hold the latitude-info?

I'm trying to make my code dependent on certain variables by changing them with a select. Is it possible to access the result outside of the function in jQuery?
js
function myCalendar(){
//global variable
var thismonth = '';
//onchange get selected month
$(document).on('change','#select_month',function(){
thismonth = $(this).val();
});
//check if empty
if(thismonth !==''){//always return empty?
var mm = thismonth;
}else{
var mm = new Date().getMonth();
}
}

I have function like this:
function GetLala() {
var lala = $.getJSON(uriLala).done(function (data) {
return data;
});
return lala;
}
Then code like this:
var data = GetLala();
console.log(data.responseJSON);
This returned me undefined. If I type this code in google chrome console - then work.

I'm pretty confused by the JavaScript scoping. I have a call to FB.api (shown below) that I would like to return a response object:
(function() {
var permissions;
FB.api("/me/permissions", "get", {access_token: options.token}, function(r) {
permissions = r;
});
console.log(permissions);
})();
Ideally, I'd like to assign FB.api to a variable, and use the anonymous function to return the r component, but it appears like that's not doable.
Why is permissions undefined? Is there a way to set permissions in the parent scope?
