JavaScript function inside HTML display in browser -


i have problem regarding javascript code. i'm trying output sum in browser, doesn't work. tried every way of displaying message in javascript: console.log(), document.write(), document.getelementbyid(). none of seems work. code looks okay, won't output anything. can me, please?

<!doctype html> <meta charset="utf-8"> <html>   <head>    <script type="text/javascript">      var sum = 0;      for(var = 0; < 1000; i++){          if(i%3 === 0 || i%5 === 0)            {            sum += i;          }         console.log('the sum is' + " " +sum);      }    </script>   </head> </html>

this code works fine here. i'm running ie11 , sum displays in console no problem. see snippet below; nothing has been changed.

maybe need open dev console? f12 in ie/edge, or settings > developer tools > console in chrome (i think).

<!doctype html>  <meta charset="utf-8">  <html>    <head>    <script type="text/javascript">      var sum = 0;      (var = 0; < 1000; i++) {        if (i % 3 === 0 || % 5 === 0) {          sum += i;        }        console.log('the sum is' + " " + sum);      }    </script>  </head>    </html>

if want have code output browser window, this, add result dom:

<!doctype html>  <meta charset="utf-8">  <html>    <head>  </head>    <body>    <div id='resultsdiv'>      <h3>results here:</h3>    </div>      <script type="text/javascript">      var sum = 0;      var resultsdiv = document.getelementbyid('resultsdiv');      (var = 0; < 1000; i++) {        if (i % 3 === 0 || % 5 === 0) {          sum += i;        }        resultsdiv.innerhtml += 'the sum is' + " " + sum + "<br />";      }    </script>  </body>    </html>

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
