node red - Javascript Nested Loop Pushing to Array -


i relatively new programming , having issues project working on.

msg.newcg2 = []; for(i=0;i<msg.newcg.length;i++){     for(j=0;j<msg.campaigngroup.length;i++){         if(msg.campaigngroup[j].col10 === msg.newcg[j]){             msg.grouptotals = msg.grouptotals + msg.campaigngroup[j].col11;     }     msg.newcg2.push(msg.newcg[i], msg.grouptotals)     } }

basically, each 1 of "ids" (integers) in msg.newcg, want each id in msg.campaigngroup , sum totals listings same id, msg.campaigngroup.col11 - push id , totals new array - msg.newcg2.

when run code, first item sent through processes, grinds halt because of memory. assume because of error in code.

where did code go wrong? sure there better ways whole, curious went wrong.

there typo in second loop , push needs happen inside outer loop.

msg.newcg2 = []; for(i=0;i<msg.newcg.length;i++){     for(j=0;j<msg.campaigngroup.length;j++){         if(msg.campaigngroup[j].col10 === msg.newcg[i]){             msg.grouptotals = msg.grouptotals + msg.campaigngroup[j].col11;         }     }     msg.newcg2.push(msg.newcg[i], msg.grouptotals)  }

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
