Question

//minimize latest news
window.document.querySelector("#ncWrapper > #nc > #action_ncMinMax").click();

//select location in weather
// $("a:contains('München')").click();

// check if variable is stored in cookie
var loc = $.cookie('loc_cookie');
if ( loc != null) {
    alert('loc existiert');
    var loc_exists = 1;
}
else { var loc_exists = 0; };

// only ask for location if no location is saved yet [functions inside if work]
if ( !loc_exists ) {
    var loc = prompt("Wählen Sie den Ort für den Wetterbericht?");
    alert('Sie haben ' + loc + ' als Ort für den Wetterbericht gewählt.');
};

    $("a:contains('" + loc + "')").click();

// save to cookie
$.cookie('loc_cookie', loc);
alert('loc in Cookie gespeichert');

Can anyone help me? the var loc = $.cookie('loc_cookie'); seems not to work. I just copy/pasted it and hope you know, what I want to make the js do.

1. look for cookie -> get cookie and save if it exists
2. if it doesn’t exist, ask for location || if if does do nothing.
3. get location.
4. save location in cookie.

Remove the “var” keyword within the if/else block. By adding it you create a new local variable.

// check if variable is stored in cookie
var loc = $.cookie('loc_cookie');
if ( loc != null) {
    alert('loc existiert');
    var loc_exists = 1;                 <- new instance of loc_exists
}
else { var loc_exists = 0; };           <- new instance of loc_exists

Should be

// check if variable is stored in cookie
var loc = $.cookie('loc_cookie');
var loc_exists;
if ( loc != null) {
    alert('loc existiert');
    loc_exists = 1;
}
else { loc_exists = 0; };

Lastly, it might be clearer to use a boolean:

if ( loc != null) {
    alert('loc existiert');
    loc_exists = true;
}
else { loc_exists = false; };
