jquery - clearTimeout(var) not working as expected -


first: searched , questions cleartimeout not working variable scope problems, not case.

i need auto-hide header after x seconds without interaction, created 2 functions, startmenutimeout , clearmenutimeout(), part of code looks that:

var menutimeout = null; function startmenutimeout(){   menutimeout = settimeout(function(){     $('[auto-header]').removeclass('-visible');   }, 2000); } function clearmenutimeout(){   cleartimeout(menutimeout); }

when user scrolls up, make header visible , start timeout, then, on mouseenter clear timeout.

problem is, doesn't clear timeout, if scroll , down few times, after 2 seconds timeout, menu goes up.

i reproduced problem on codepen, click here access.

after blazing fast comments of kevin b , carcigenicate solved it. thing is, every time call settimeout(), creates new id, then, if attributing timeout id variable, override, losing reference previous one.

the solution clearing timeout before setting new one, 1 timeout active @ time.

the code looks this:

var menutimeout = null; function startmenutimeout(){   cleartimeout(menutimeout);   menutimeout = settimeout(function(){     $('[auto-header]').removeclass('-visible');   }, 2000); } function clearmenutimeout(){   cleartimeout(menutimeout); }

click here access updated pen.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
