javascript - jquery on handler to fire when setting element value through jquery -


this question has answer here:

i have event handler fires whenever user clicks box , enters text:

$( '#foo' ).on( 'keyup change paste', function () {    console.log('this event handler has fired.');     });

i have piece of code where, instead of allowing user type in themselves, setting value of element myself:

$("#foo).text('bar');

while code works, setting text value of element named foo value of bar, not trigger event handler. on event missing, apart keyup change paste i'm using?

those events registered when user initiates them. since making change yourself, have simulate event using trigger().

$( '#foo' ).on( 'keyup change paste', function () {     console.log('this event handler has fired.');      });    $('#foo').trigger('change').val('triggered');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <textarea id="foo"></textarea>

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...
