JavaScript spēlīte: Color Lines


Recommended Posts

Globāli mainīgie piemēram ir visi kas tiek izmantoti iekš https://github.com/arnisritins/Color-Lines/blob/master/lines.js#L346 timeout'a. Mainīgais "blocked" nav redzams no šīs rindas un no šīs (jo nav definēts ne funkcijā, ne iekš closure kas to ietver) tāpēc vērtības nonāk window.blocked mainīgajā.

 

Un 50+ rindu funkcijām piemēri ir: https://github.com/arnisritins/Color-Lines/blob/master/lines.js#L180 un https://github.com/arnisritins/Color-Lines/blob/master/lines.js#L552

Man šķiet, ka tev nav:

 

http://jsfiddle.net/cZU52/

function log(s){
    $('#log').append('<div>'+s+'</div>');
}

(function(){
  var foo = 1,
      
      
      outer = function () {
        log(foo);
        foo = 2;
        bar = 7;
        
        window.setTimeout(function () {
          log(foo);            
          log(window.foo);
          log(bar);
          log(window.bar);
        }, 1000);
      };
  
  outer();
}());

output:

1
2
undefined
7
7

Kā redzams, foo nav globālais.
