javascript:variable value passing from javascript to php

Question

I have a javascript file pet.js. I want to pass a value of variable in test.php. But i can't.

my pet.js is like

$('#pmWorkOrderDetailsPage').live('pageshow', function(event) {
var id = getUrlVars()["id"];
$.get("test.php", { test1: id } );
$.getJSON('pmworkorderdetails.php?id='+id, displaypmWODetails);
});

function displaypmWODetails(data) {
 ..............code..........
 }

My test.php is like

<?php
$ms = $_GET["test1"];
echo $ms;
?>

But it is not working. I tried with Ajax and post method.

It will be best if I can store the variable value on the session in test.php.

Thanks in advance for any help.

You have an echo statement in test.php, but you're not using a callback to handle that data in pet.js. What exactly do you want to do with the output of test.php? — Andrew

What do you mean by 'not working'? Do you get any errors in your console? Is 'id' filled correctly before you do the ajax call (log it in your console)? — Asciiom

try echo json_encode($ms);. Also, you may need to add a json header — Viktor S.

Try some more using xmlhttprequest. So many people have made it. Search for "xhr javascript example". — oxygen

Where's your callback for the first get request? You're making the request and passing in a parameter, but there is no function being called once it returns with something. Also bear in mind that it will be asynchronous, so if getjson relies on the data that comes back from it, you'll need to do that in the callback. — Dawn

1 do not use getUrlVars() it can make site vulnerable to xss

$('#pmWorkOrderDetailsPage').live('click', function(event) {
var id;// get id
$.get("test.php?id="+id,function(data){

var result=$.parseJSON(data);
 alert(result["content"])
 });

 })

test.php

<?php

 $id=$_GET['id'];
 $data=array();
  $data=array("content"=>$id);
 echo json_encode($data);
?>

how it could be possible that alert shows the right id and you don't have id in test.php ?
