Heya, Amzul.

To do this, you'll need to use an iframe.

sorry for 2 in a row....

can someone explian me the syntax of this :

AIM = {
 
    frame : function(c) {
 
        var n = 'f' + Math.floor(Math.random() * 99999);
        var d = document.createElement('DIV');
        d.innerHTML = '<iframe style="display:none" src="about:blank" id="'+n+'" name="'+n+'" onload="AIM.loaded(\''+n+'\')"></iframe>';
        document.body.appendChild(d);
 
        var i = document.getElementById(n);
        if (c && typeof(c.onComplete) == 'function') {
            i.onComplete = c.onComplete;
        }
 
        return n;
    },

i took it from here
whats AIM a class?
whats frame : means? is it like 'go to' like an anchor?
why there is a ',' (comma) affter the end of the function?

and in the main html

<form action="index.php" method="post" onsubmit="return AIM.submit(this, {'onStart' : startCallback, 'onComplete' : completeCallback})">

the way i underrstand, it calls to a sequence of function. am i right?

Heya, Amzul.

In this case, AIM is a generic object that contains an element named 'frame'. That element is a function object (see this article).

The syntax for a JavaScript object (known as JSON) is:

variable =
    {
        'element name'  : 'value',
        'name'          : 'James',
        'age'           : 32,
        'etc.'          : function() { return 5; }
    };
 
alert(variable.name);       // 'James'
alert(variable.age);        // 32
 
alert(variable['etc.']);    // 'function() { return 5; }'
alert(variable['etc.']());  // 5
