javascript - JQuery - $ is not defined -


i have simple jquery click event

<script type="text/javascript">     $(function() {         $('#post').click(function() {             alert("test");          });     }); </script>

and jquery reference defined in site.master

<script src="<%=resolveurl("~/scripts/jquery-1.3.2.js")%>" type="text/javascript"></script>

i have checked script being resolved correctly, i'm able see markup , view script directly in firebug, must being found. still getting:

$ not defined

and non of jquery works. i've tried various variations of $(document).ready , jquery etc.

it's mvc 2 app on .net 3.5, i'm sure i'm being dense, everywhere on google says check file reference correctly, have checked , checked again, please advise! :/

that error can caused 1 of 3 things:

  1. your javascript file not being loaded page
  2. you have botched version of jquery. happen because edited core file, or plugin may have overwritten $ variable.
  3. you have javascript running before page loaded, , such, before jquery loaded.

you should check firebug net panel see if file being loaded properly. if not, highlighted red , "404" beside it. if file loading properly, means issue number 2.

make sure jquery javascript code being run inside code block such as:

$(document).ready(function () {   //your code here });

this ensure code being loaded after jquery has been initialized.

one final thing check make sure not loading plugins before load jquery. plugins extend "$" object, if load plugin before loading jquery core, you'll error described.

note: if you're loading code not require jquery run not need placed inside jquery ready handler. code may separated using document.readystate.

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...
