javascript - Accessing the properties of an object without knowing the names of those properties not working -


i have index.php with:

these php lines

$sql = "select * voedingsmiddelen"; $result = mysqli_query($conn, $sql);

on same page have code extract data table , put in array.

var array = <?php echo json_encode( mysqli_fetch_all( $result, mysqli_assoc ) ) ?>; var arraytype = typeof array; alert('type: '+arraytype);  var i=0; for(key in array) {     alert('for loop working');     if(data.hasownproperty(key)) {         var value = data[key];         alert(value);     } else {         alert('has no property');     } }

i 1 alert saying 'type: object'. "gettype" working. other alerts not displaying. doing wrong?

hasownproperty returns boolean value indicating whether object on calling has property name of argument here.so try this

for (var i=0; i<array.length; i++) {     alert('for loop working');     if(array.hasownproperty(i)) {         var value = i;         alert(value);     } else {         alert('has no property');     } }

or in case this:

var i=0; for(key in array) {     alert('for loop working');     if(array.hasownproperty(key)) {         var value = key;         alert(value);     } else {         alert('has no property');     } }

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
