Hello!

I have got URL address like this:

http:\\www.ZZZZ.com?param=10

Is it possible to call and read the GET param parameter value in Javascript?

I mean such code in PHP language:

$_GET["param"]

Kindest regards
Marcin

That isn't a URL. The slashes are going in the wrong direction.

And please use example.com (or net or org) for examples (unless you're
a representative of KWIKWEB)

You can parse window.location.search. There isn't a built in system
that splits key/value pairs on ampersands and semi-colons and
constructs an object for you.

Yes.
It is possible. As David Dorward says above you must
parse window.location. If you cannot made this alone
you can use this function.
    /**
            * This function assumes a url
            * or other string as a argument
            * and return hash with url-s
            * parameters in the type:
            * myhash['getparamname'] = getparam val
            * usage:
            * var $GET = parseWindowLocation(window.location.href);
            * alert($GET['valname']);
            * will show the value of GET
            * variable undefined otherwise.
            * @param string aLocation
            * @author
            * Georgi Naumov
            * gonaumov@gmail.com
            */
            function parseWindowLocation(aLocation)
            {
                    var re = /[?&]([^=]+)=([^&]+)/g;
                    var maches = null;
                    var urlParts = new Array();
                    maches = aLocation.match(re);
                    if(maches != null)
                    {
                        for(var i=0;i< maches.length;i++)
                        {
                                var urlPart = maches[i].split("=");
                                urlParts[urlPart[0].substr(1)] = urlPart[1];
                        }
                    }
                    return urlParts;
            }

Good Luck !

Hello!

Thank you for your help.
I have tried this one:

Some guy from Polish javascript newsgroupds helped me with finding it.

Thank you both for help

Try this one, tested in Safari, Firefox and Opera (wrapped for
posting):

function search2obj(){
// Get search string
var s = window.location.search;
var obj = {};

// Return if no values
if (s.length < 2) return obj;

// Remove ?, fix '+' - change to %20
s = s.substring(1).replace(/\+/g,'%20');

// Split into bits
var bits = s.split(/[=&]/);

// Decode & convert to object
for (var i=0, len=bits.length; i<len; i++) {
obj[decodeURIComponent(bits[i++])] =
decodeURIComponent(bits[i]);
}
return obj;
}

report( search2obj() );

// Just for help - show object property/value pairs
function report(obj){
var p, t = [];
for (p in obj){
t.push(p + ': ' + obj[p]);
}
alert(t.join('\n'));
}
