I have a function in JS with a JQuery method, inside a script in HTML which gets data from a .txt.

In this .txt I have one line of text like this:

Test_1_NoOk

In the function, I make a split() and get the character "1" in a variable, as shown below.

$.get("Text.txt", function(data) {

var parts= data.split('_');
fail= parseInt(parts[1]);

});

After processing this information, I want the global variable "fail" to get that "1" and be painted in HTML division.

But when I paint it, it always stays like "0", because the value at the initialization of the varibale is that (it doesn't change).

Any way to overwrite the value of the global one, inside the function?

you said `fail` but your assigning it to a variable `errores` – Roljhon Mar 14 '17 at 11:11
First thing i would do is to add this line in the start of your `$.get`. `console.log(data)`. then look in your log and see if it returns what it shall – Carsten Løvbo Andersen Mar 14 '17 at 11:11
when do you output it to html? you should try moving it to the request callback function – Tomasz Rup Mar 14 '17 at 11:12
`$.get` is asynchronous, therefore you need to work with the response within the callback. Otherwise the value may not yet be set. See the duplicate questions I marked for more information – Rory McCrossan Mar 14 '17 at 11:13
@Roljhon my mistake, editted. – Luis Rojo Mar 14 '17 at 11:38
@TomaszRup I output it in a div of th HTML with the sentence: `document.write(fail);` – Luis Rojo Mar 14 '17 at 11:39
