I have .js and .php files and html pages. I am including js files in html files and php files in js files.

I want to pass ‘cat’ value from js file to php file using address bar when I go to this page;

/demo/convert.html?cat=volume

But I have no idea how to do this.

By the way, this is a blacberry project and I am not sure if I can use address bar to pass value. Any idea is welcome.

    Test this sample code with an URL like :
    http://sputnick-area.net/test/index.php?foobar=works_as_a_charm

    <?php

$var = $_GET['foobar'];

echo <<<EOF
<html>
<head>
<title></title>
</head>
<body>
demo of using PHP GET variable in Javascript :
<script type="text/javascript">
alert("$var");
</script>
</body>
</html>
EOF

?>

    Edit :

    if you’d like to handle GET variables from within JavaScript, consider the following HTML + JavaScript sample : http://sputnick-area.net/test/index.html?foobar=works_as_a_charm

    <html>
<head>
<title></title>
</head>
<body>
<script type="text/javascript">
var vars = [], hash;
var hashes = window.location.href.slice(
    window.location.href.indexOf('?') + 1
).split('&');

for(var i = 0; i < hashes.length; i++) {
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    vars[hash[0]] = hash[1];
}

alert(vars['foobar']);
</script>
</body>
</html>
