jQuery/JavaScript read a local text file
For some reason I got stuck with this 'thing'
As you can see I want to try to read the count.txt. This is working perfectly but for some reason the
alert(code);
is coming up after the
alert("The number can't be smaler then 0");
For me it makes no sense because I'd call the alert(count) before the alert("The number...") Any ideas why the jQuery function (alert) is called after the other alert?
function leftFunction() {
jQuery.get('count.txt', function(data) {
var count = data;
alert(count);
});
scrolling = true;
if(number == 0) {
alert("The number can't be smaler then 0");
return;
}
number--;
document.getElementById("myImage").src = "latest" + number + ".jpg";
}
As Red fx says in the comments, it's related to JavaScript being asynchronous. Try something like this instead:
function leftFunction() {
jQuery.get('count.txt', function(data) {
var count = data;
alert(count);
}).done(function() {
scrolling = true;
if (number == 0) {
alert("The number can't be smaler then 0");
return;
}
});
number--;
document.getElementById("myImage").src = "latest" + number + ".jpg";
}
