javascript - How to pass Variable Values from JS to PHP (not via form) -


i'm new here. i'm trying pass variable values client php server. looked matter , saw many answers, of them regarding sending form values. i'm trying transfer actual variable values. simple example (multiple instances of following button):

 $("#aam").click(function () {         var e = confirm("are sure?")         if(e == true)         {            $(this).hide('slow');            counter++;         }   });

every time button clicked counter goes 1 (after "if" checks). want counter value server, how should done. search learned ajax unfortunately couldn't adjust own scenario... tried ajax request:

$("#click_ajax").click(function() {    $.ajax({        type: 'post',        url: 'c:/xampp/htdocs/abby/test.php',        data: {counter}      }); });

with php:

<?php       $counter = $_post['counter'];            echo $counter  ?>

unfortunately didn't work - whatever do, "notice: undefined index: counter in c:\xampp\htdocs\abby\test.php on line 9" error via xampp. hope can assist me. in advance,

abby.

you not send correct data thru ajax request. try this:

js:

 var ajaxurl = 'abby/test.php';   $.ajax({    type: "post",    url:  ajaxurl, //check if in ajax file    data: {      action: "sendcounter",      counter: counter    } }).always(function() {  }).done(function(data) {   console.log(data); // should server counter number  });

php (more elegant way of ajax file):

if (isset($_post['action'])) {     $straction = $_post['action'];     switch ($straction)     {        case 'sendcounter':           if (isset($_post['counter']))           {               echo $_post['counter'];           }        break;     } }

hope helps.

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
