javascript - Set value to an aria-controls input -


i want set input aria-control value. can't using traditional jquery way.

my code one:

function showmessage() {    var message = jquery("#texttodisplay").val();    $("#example").text(message);  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="text" id="texttodisplay" />  <input type="button" value="add message" onclick="showmessage()" />  <input aria-controls="example" type="text">

how can set value?

change selector this.your selector target id not aria-controls use attr selector.also input not have text() property change val()

function showmessage() {   var message = jquery("#texttodisplay").val();   $("input[aria-controls=example]").val(message);    }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="text" id="texttodisplay" />  <input type="button" value="add message" onclick="showmessage()" />  <input aria-controls="example" type="text">

for below terry comment use addeventlistener instead of inline click function.that click function in dom this

$('#click').click(function() {    var message = jquery("#texttodisplay").val();    $("input[aria-controls=example]").val(message);  })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <input type="text" id="texttodisplay" />  <input type="button" id="click" value="add message">  <input aria-controls="example" type="text">

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...
