How do I access the header using AJAX?

Question

Say for example I had had page with the url of:

foo.php?bar='blob'

Is it possible to get the value of blob?

For example:

xmlhttp.open("GET","new_film_pro.php?x="+blob,true);

Thanks

Apologies for not being very technical. – Sheldon Apr 14 '11 at 10:41 — Sheldon, Apr 14 '11 at 10:41

If you are using jsp then

var blob="<%request.getParameter('bar')%>";
xmlhttp.open("GET","new_film_pro.php?x="+blob,true);

You should already know the value, if your xmlhttp call includes it, just parse the string

EDIT

function getArgs(url) {
    var args = new Object();
    var query = url.split("?")[1];
    var pairs = query.split("&");
    for (var i = 0; i < pairs.length; i++) {
        var pos = pairs[i].indexOf('=');
        if (pos == -1) continue;
        var argname = pairs[i].substring(0, pos);
        var value = pairs[i].substring(pos + 1);
        args[argname] = unescape(value);
    }
    return args;
}
var args = getArgs("testing.php?foo=bar");
txtValue.value = args.foo;

Well blob is a variable, use it... you could make it globally available ie. outside the function. – Kenneth Jakobsen Apr 14 '11 at 11:23
It doesn't use it - my example is purely demonstrating what I want to do. – Sheldon Apr 14 '11 at 11:59
Ok, but you still know the url right?, then you'll need to parse that instead, Updated my post – Kenneth Jakobsen Apr 14 '11 at 12:01
